Computer Application in Business-The first non-scientific use of computers concerned routine clerical work. Office administration had previously used such aids as punched -cards accounting machines and adding machines. It was natural progression to make use of computers. Computing procedures for clerical duties were relatively simple to develop since they were already well defined and the repetitive nature of many of the tasks made them very suitable for the computer.
In
the future, the impact is likely to be even greater. Microelectronic technology
is enabling officers to function faster and more efficiently, and the cheapness
of the technology means computing is within the grasp of even the smallest
business. At a general office level, word processing systems and personal
computers are already changing office practice and organization. Word
processors are particularly useful for preparing reports that may need to go
through one or more revisions and for producing standard letters and documents.
They provide the capability to insert or delete words, lines or paragraphs, and
to print out drafts and final copies at speed. System may include special
purpose packages for specific applications such as merging address list,
producing a range of documents for insurance quotations and purchase orders,
and even dictionary packages which signal and correct mis-spellings. Specific
hardware features may include specially designed terminals, personal computers
or workstations.
The
computer is used for at least three basic corporate purposes:
- Preparation
of transaction documents
- Control
of operations
- Decision-making
Preparation of transaction documents such as pay
slips, invoices and receipts is the simplest task that the computer can be put
to, the only requirement being that the process of preparation be standard,
unchanging and easily specified.
A
great deal of routine business activity consists of effectively controlling
various functions, plans and operations. The computer can assist in this
process by automatically contrasting actual performance with planned
performance, highlighting only the areas of discrepancy for reward or censure.
It is said that management is decision making, and the
manager spends his time making decisions. This is no doubt a limited point of
view as the manager spends his day in many other important activities such as
reviewing, persuading and investigating. There is no doubt, however, that
decision making is his most important activity and it is here that the computer
can give him the greatest and most significant help.
The
computer can be applied to almost every area of management. Its benefits will
be depend on the importance of the area of application to the company, how
conductive it is to computerization and how well the system has been designed
and implemented.
Computer Application in
Project Management: Project
management which encompasses planning, scheduling and monitoring phases of a
project assumes a very important role considering the present trends in modern
projects. The process of project management which does not operate on a self
regulation mechanism needs constant feedback on the occurrences at predetermined
points for the events to conform to planned schedules. The basic need for effective
monitoring depends solely upon timely, reliable, accurate and sufficient
information on various aspects of a project, emanating from different agencies
flowing through different operations levels and echelons(rank, authority) of
management. The various interacting agencies could be clients, collaborators,
consultants, vendors, contractors, financiers, statutory bodies, functional
groups, who are geographically dispersed over the globe.
The various phase of a typical project could be broadly
identified as Feasibility study, Detailed Project Report, Process Design,
Detailed Engineering, Procurement, Construction and Commissioning. To capture,
process and analyse information for a quick and timely decision making in such
a dynamic environment of projects ( large refineries etc) with investments to a
tune of Rs 3000-4000 million, involving monitoring of 35000-40000 activities
spanning a life cycle of 36-40 months in preparation
prefabrication/construction drawings, procurements of equipment, bulk material
allocation construction planning and material allocation etc., a tool with
matching capabilities is inevitable.
The integrated project management system encompasses the
following subsystems:
- Project
Profile
- Activity
Networks
- Engineering
- Procurement
- Construction
- Commissioning
- Human
Resources
- Cost/Finance
The computer finds
application in project management area because of its speed, accuracy, memory
and stored program features. The difference computer application categories
are:
- General and
Clerical
- Planning and
Decision Models
- Information
oriented
- What if,
i.e., future scenario type
Computer in Personnel
Administration: During the past several decades personnel
function has been transformed from a relatively obscure record keeping function
to a central and top-level management function in the organization. There are
many factors that have affected this change- technology advances, recognition
of human rights, professionalization, government legislations etc. Probably the
most important factor is the general
recognition of human beings in an organization as one of the most important
resources.
The
computer is viewed as the fourth greatest break-through in history to aid man
in his thinking process and decision making ability. Even with the problems
inherent with computer use, the fact remains that computers are increasingly
accepted as an integral part of organizations. A carefully planned and
implemented computerized personnel management system can provide timely and
accurate information for numerous personnel decisions. Computers play a vital
role in personnel management and administration functions. Computers along with
word processing facilities are now very useful and edited outputs can now be
produced. Various areas under personnel management have been explained, where
computerization is used. The objective of the personnel management is to build
and provide the right type of manpower at the right time to meet the business
requirements of organization efficiently and effectively. Main activities
carried out in personnel management are:
- Manpower Planning
- Human Resource Development
- Selection and Recruitment
- Compensations and Benefits
- Industrial Relations and Grievance
Handling
- Establishment and Personnel Records
- Collective Bargaining
Computer Applications in Marketing
and Manufacturing: In many companies with extensive marketing activities,
the marketing information system is among the least developed of these
companies information systems. One
reason for this is that improved information systems for marketing often do not
receive priority because they cannot be justified on a cost savings basis, and
the benefits of the systems may be largely intangible and not readily
observable. These benefits may nevertheless be very real and may include better
information for marketing decisions ( such as for product pricing) as well as
better customer service.
In
some companies with weak marketing information systems, marketing is the most
critical activity. Not only is the information that marketing management
receives important, but also the information that marketing generates is vital
to the rest of the organization. For example, marketing provides sales
forecasts that serve as the basis for production schedules, cash flow
projections, and profit plans. Because of this, the impact of ineffective
marketing information system is felt throughout the organization. The major marketing information subsystems
are:
- The Sales information system:
a. Sales support
b. Sales analysis
c. Customer analysis
- The market research and intelligence
information system:
a. Customer research
b. Market research
c. Competitor intelligence
- Promotion and advertising information
system
- New product development information
system
- Sales forecasting information system
- Product planning information system
- Product pricing information system
- Expenditures control information
system
The role of production in organization is
to provide a product that the market demands. This means (1)
producing the quantity of products needed by
customers, (2) maintaining the quality of the products established by the
product specifications, and (3) producing within the cost constraints imposed
by the production control system. Production activities involve transforming
energy, labor, raw materials, purchased parts and components into finished
products by production or assembly activities. For the purposes of this
discussion, raw materials, purchased parts and components are all referred to
as materials, and no distinction is made among them. There are four general
types of production: (1) continuous-flow production, such as is used in oil
refineries; (2) repetitive or mass production, which is used in automobile
parts production and assembly activities; (3) project production, such as is
used in ship manufacturing; and (4) discrete, job-oriented production, in which
production activities may be discontinuous or in which a ‘batch’ of a
particular product is produced in a few hours, days, or weeks, after which the
“production run” is terminated.
Computer Application in
Materials Management: Materials management is an area in which
the computers can be put to beneficial use. Since computerization of inventory
control will provide better control and profitability, there is rich potential
for computerization in material management field. Material management has emerged
as an independent function. Top management has been gradually giving greater
importance to this area. Right information available at the right time can
significantly improve the quality of decisions. Information for planning and
control has always been potentially available. However, between ‘potential’ and
‘actual’ have stood the two stumbling blocks of time delays and prohibitive
cost. It is here that the computer has come to the aid of materials management.
Several
studies in the field of inventory control have revealed that materials account
for more than 60 percent of the sale value. However, these costs vary from
industry to industry. In some industries like sugar and general engineering,
the material costs are over 70 percent of the sale value. Stocking cost of
materials in the Store Departments results in inventory keeping cost. In Indian
conditions with meteorological factor changing from season to season, the
carrying costs are estimated to be approximately 20 to 25 percent of the cost
of materials. Information management in the field of inventory control can thus
easily lead to 5 percent reduction in material costs.
The
objectives of an integrated approach in the field of materials management can
be:
- To minimize investment in inventories;
- To provide materials of a specified
quality at the lowest cost;
- To perform functions of material
handling and storage so that keeping costs are minimized;
- To cut cost through standardization,
value analysis, waste control and import substitution;
- To improve procedures and to delegate
authority and responsibility at various levels of materials management
The scope of materials management varies from
organization to organization; so do the major activities covered by it. We assume
a fairly wide scope for material management and consider the following
activities to be covered by it:
1. Material planning/specification
2. Requirements determination
3. Inventory management
4. Purchasing
5. Production scheduling
6. Stocking
7. Allocation
8. Distribution
Office Automation: Office automation is defined as using
computer and communications technology to help people better use and manage
information. Office automation technology includes all types of computers,
telephones, electronic mail, and office machines that use microprocessors or other
high technology components. People who use office automation are often called
knowledge workers- senior executives, managers, supervisors, analysts,
engineers and white-collar workers. In most offices, information is the end
product and is essential for conducting the company’s business. Office
automation provides knowledge workers with information producing systems to
collect, analyze, plan, and control information about the many facets of the
business, using text, voice, graphics and video display technology.
People: ---- Although it takes people to complete
work, it is the way people work that accounts for productivity. In recent
years, the trend has been towards people working together to accomplish more.
This is called workgroup computing, which means a number of knowledge workers,
each with different tasks, jobs or duties, work together towards a common goal.
In large companies, there may be dozens or hundreds of workgroups. In smaller
companies, everyone is part of the worksgroup.
Ergonomics: ----- Organizations learned that office
could not be automated in the same way the factory was automated, and the field
of ergonomic began to emerge. Office tasks involve a great deal of thinking and
decision making. As a result, office systems must be flexible and versatile.
Moreover, they must be designed so any knowledge worker, regardless of
background can easily use them. This is called ergonomics, the study of how to
create safety, comfort and ease of use for people who use machines. It is not a
new field of study; in fact, it has existed for over a hundred years. With the
advent of computers, ergonomics engineers became particularly interested in
office automation system, furniture and environments for the knowledge worker.
Office furniture companies soon introduced ergonomically designed chairs and
equipment. Ergonomics has played a significant role in helping people use
technology more effectively.
There are five primary technologies used in
managing information in office automation:
- Text or written words
- Data, as in numbers or other non-text
forms
- Graphics, including drawings, charts
and photographs
- Audios, as in telephone, voice mail,
or voice recognition systems
- Video, such as captured images,
videotapes or teleconferencing.
In the past, these forms of information
were created using different technologies. Today,
The computer integrates these media and others as
well. Data, sound and images can all be entered into a computer, stored and
translated into the kind of output we need. It is now common to see knowledge
workers in workgroups using a special type of software designed specifically
for them and their work. This application software, called groupware, lets
networked PCs and workstations share information and electronic documents from
both corporate and on-line sources.
Office Automation Systems:---- Office automation uses computer-based systems to
provide information to help knowledge workers make decisions that benefit the
business. Office automation systems comprise many distinct subsystem: text
management systems, business analysis systems, document management systems and
network and communication systems.
Text Management--- A text management system is a computer system designed
to work with the written or typewritten word. It includes all kinds of
typewriters, word processing systems, PCs with word processing, desktop
publishing and text editing systems and even computerized typesetting
equipment. Text management systems are used for tasks like writing memos,
notes, letters and other short documents, printing envelopes and labels,
preparing pre-printed forms such as invoices, composing complex documents such
as proposals and reports, retrieving and editing documents such as contracts,
creating display documents like newsletters, etc.
Business Analysis---- Managers need solid data from which to extract
the information necessary to make good decisions for the business. In the past,
these knowledge workers had to rely on their experience and other personal
factors to make decisions. A business analysis system provides data that, when
used with the proper software, helps its users better understand the business
environment and make more effective decisions. Other software tools for
performing analysis that are commonly used in large companies are Decision
Support System, expert systems and Executive Support Systems.
Document Management--- Document management systems aid in filing,
tracking and managing documents, whether they are paper, computer based, micrographics
or purely electronic. Office automation demands that data be immediately
accessible and retrievable. For that reason, we are slowly moving away from
paper and toward document forms that can be stored on the computer.
Network and Communication Management--- Today, knowledge
workers have many ways to communicate with one another, primarily by voice,
fax, and e-mail. They can communicate in real time, via phone or computer. They
can also communicate using computer controlled PBX telephone systems to record
a digital message and leave it in the recipient’s electronic mailbox. These
system are called network and communication management systems. The network and
communication management systems include telephone, electronic mail, voice
messaging systems, teleconferencing and fax machines.
Electronic Publishing:- Electronic publishing is one of the most widely used forms
of office automation. This category includes office tools that have become
staples in our personal and professional lives, such as word processing and
desktop publishing software. Microsoft Word, part of the Office 365 product
suite, is the most widely used solution with an estimated 60 million monthly active Office 365 commercial
customers.
Other
office automation solutions such as content management systems (CMS) have become
popular and allow employees to easily contribute to, schedule, or edit digital
content. CMS solutions are cloud-based. This means that they can be accessed
from anywhere by any number of users. Moreover, low-code technology such as
drag-and-drop functionality allows non-technical users to easily create and
manage their own web content. One of the most well-known examples of a CMS is
WordPress.
Advantages of Office
Automation are:
1.
Office automation can get many tasks
accomplished faster.
2.
It eliminates the need for a
large staff.
3.
Less storage is required to store
data.
4.
Multiple people can update data
simultaneously in the event of changes in schedule.[2]
Industrial Applications: Computers are used to perform several tasks in
industries like managing inventory, designing purpose, creating virtual sample
products, interior designing, video conferencing, etc. Online marketing has
seen a great revolution in its ability to sell various products to inaccessible
corners like interior or rural areas. Stock markets have seen phenomenal
participation from different levels of people through the use of computers.
CAD/CAM: An increasingly popular tool for product design is CAD. CAD systems
are computer programs or integrated packages for workstation hardware and software
that allow the user to draw and easily modify product designs on a computer
screen. Advanced CAD systems provide designers with at least three major
benefits.
- Graphics capabilities—CAD systems
allow the designer to view a product from different perspectives,
including three-dimensional rotations, and various cross-sections. The
designer can also make proportional changes in scale, or change the angle
of an arc with the click of a computer mouse rather than having to redraw
the entire product.
- Design, Storage and retrieval--- Some
CAD systems can store the design characteristics of existing products and
components. For example, If a company needs a gear for a new product, the
designer can enter the relevant information about the gear, such as its
diameter, tooth pattern and required hardness, into the CAD systems. The
CAD systems determine whether the company is already using an identical or
sufficiently similar gear, in which case a new one is unnecessary. If not,
a gear, which has similar properties, may exist. The designer can then use
the design of this similar gear as a starting point for the new gear. This
capability not only promotes the use of common components but also reduces
design time.
- Automatic evaluation of specifications---
One of the most time-consuming aspects of design for highly technical products
is calculating whether or not product specifications, such as strength,
heat resistance or aerodynamic drag, are satisfied. These calculations can
be programmed into some CAD systems so that whenever the designer changes
the design( by altering the shape or material to be used), these
performance characteristics are recalculated automatically and compared to
the product requirements.
Even greater time and cost reductions have resulted
from recent advances whereby CAD-engineered designs are converted automatically
into software programs for computerized production machines. These are called
CAD/CAM systems. This automatic conversion eliminates the costly and time
consuming steps of having a person convert design drawings into a computer
program for computer- controlled production equipment, such as robots or
machine tools. CAD and CAD/CAM systems are not used by large automotive or
electronics companies alone. Future Enterprises, the largest maker of wedding
jewelry in the United States, reported that its CAD/CAM system reduces the time
required to design and make jewelry from five months to one week.
Product Data Management (PDM)--- One of the
major manufacturing challenges is to maximize the time-to-market benefits of
concurrent engineering while maintaining control of your data and distributing
it automatically to the people who need it, when they need it. The way PDM
systems cope with this challenge is that master data is held only once in a
secure ‘vault’ where its integrity can be assured and all changes to it
monitored, controlled and recorded.
Duplicate reference copies of the master data, on the
other hand, can be distributed freely, to users in various departments for
design, analysis and approval. The new data is then released back into the
vault. When a change is made to data, what actually happens is that a modified
copy of the data, signed and dated, is stored in the vault alongside the old
data which remains in its original form as permanent record. The following are
some of the benefits of the PDM system:
- Reduced
Time-to-Market
- Improved
Design Productivity
- Better use
of Creative Team Skills
- Data Integrity
Safeguard
- Better Management
of Engineering Change
Feature Prototyping:- One of the problems with product design is
getting an intimate feel for the appearance and behavior potential of a
product. Now there are software packages that can generate computer prototypes,
which can be distributed and tested by actual customers. Usage data from these
tests is collected automatically and used to refine product specifications
until they precisely meet the customers’ needs. This process helps in ensuring
the market success of the new product before costly and time-consuming
investments in engineering and manufacturing are made. Better than
communicating with customers using written specifications, static drawings,
flip charts, or multimedia authoring tools, feature prototyping using fully
functional prototypes provide accurate and valuable feedback to the company
based on customers’ experience that can make the difference between a
resounding market winner and an embarrassing.
Library Information System: Prior to computerization,
library tasks were performed manually and independently from one another.
Selectors ordered materials with ordering slips, cataloguers manually
catalogued items and indexed them with the card
catalog system (in which all bibliographic data was kept on a single index
card), fines were collected by local bailiffs, and users signed books out
manually, indicating their name on cue cards which were then kept at the circulation
desk. Early mechanization came in 1936, when the University of Texas began
using a punch card system to manage library circulation. While the punch card
system allowed for more efficient tracking of loans, library services were far
from being integrated, and no other library task was affected by this change.
1960s: the influence of computer
technologies
Following this, the
next big innovation came with the advent of MARC
standards in the 1960s which coincided with the growth of computer
technologies – library automation was born. From this point onwards,
libraries began experimenting with computers, and, starting in the late 1960s
and continuing into the 1970s, bibliographic services utilizing new online
technology and the shared MARC vocabulary entered the market; these included OCLC (1967), Research Libraries Group (which has since
merged with OCLC), and Washington Library Network (which became Western Library
Network and is also now part of OCLC).[
1970s–1980s: the early integrated
library system
The 1970s can be characterized
by improvements in computer storage as well as in telecommunications. As a
result of these advances, ‘turnkey systems on microcomputers,
known more commonly as integrated library systems (ILS) finally
appeared. These systems included necessary hardware and software which allowed
the connection of major circulation tasks, including circulation control and
overdue notices.
As the technology developed, other library tasks could be accomplished through
ILS as well, including acquisition, cataloguing,
reservation of titles, and monitoring of serials
1990s–2000s: the growth of the
Internet
With the evolution of
the Internet
throughout the 1990s and into the 2000s, ILSs began allowing users to more
actively engage with their libraries through OPACs and online
web-based portals. Users could log into their library accounts to reserve or
renew books, as well as authenticate themselves for access to
library-subscribed online databases. Inevitably, during this time, the
ILS market grew exponentially. By 2002, the ILS industry averaged sales of
approximately US$500 million annually, compared to just US$50 million in 1982.
Mid 2000s–Present: increasing
costs and customer dissatisfaction
By the mid to late
2000s, ILS vendors had increased not only the number of services offered but
also their prices, leading to some dissatisfaction among many smaller libraries.
At the same time, open source ILS was in its early stages of testing. Some libraries
began turning to such open source ILSs as Koha
and Evergreen. Common reasons noted were to avoid
vendor lock in, avoid license fees, and participate in software development.
Freedom from vendors also allowed libraries to prioritize needs according to
urgency, as opposed to what their vendor can offer.
Libraries which have moved to open source ILS have found that vendors are now
more likely to provide quality service in order to continue a partnership since
they no longer have the power of owning the ILS software and tying down
libraries to strict contracts. This has been the case with the SCLENDS consortium. Following the
success of Evergreen for the Georgia PINES library
consortium, the South Carolina State Library along with some local public
libraries formed the SCLENDS consortium in order to share resources and to take
advantage of the open source nature of the Evergreen ILS to meet their specific
needs. By October 2011, just 2 years after SCLENDS began operations, 13 public
library systems across 15 counties had already joined the consortium, in
addition to the South Carolina State Library. Librarytechnology.org does an
annual survey of over 2,400 libraries and noted in 2008 2% of those surveyed
used open source ILS, in 2009 the number increased to 8%, in 2010 12%, and in
2011 11% of the libraries polled had adopted open source ILSs. The following
year's survey (published in April 2013) reported an increase to 14%, stating
that "open source ILS products, including Evergreen and Koha, continue to
represent a significant portion of industry activity. Of the 794 contracts
reported in the public and academic arena, 113, or 14 percent, were for support
services for these open source systems." [
2010s–Present: the rise of cloud
based solutions
The use of cloud
based library management systems has increased drastically since the rise of
"cloud" technology started. Some common management systems include
Libramatic, Aura Software and Librarika. Many modern cloud based solutions
allow automated cataloging by scanning a book's ISBN. This technology was
pioneered by Libramatic, although it is currently in use by systems such as
LibraryWorld. Librarika has a method called "Smart Add" that lets
Librarians to add book automatically by just inputing the ISBNs. In addition,
Librarika offers free library creation with built-in OPAC for up to 10,000 book
titles with the ability to get more free titles for non-profit and charities, which
serves well for many school, college and other small libraries.
Digital Image Processing: Digital image processing is the use of
computer algorithms to perform image processing on digital images. As a subcategory or field of digital
signal processing,
digital image processing has many advantages over analog
image processing.
It allows a much wider range of algorithms to be applied to the input data and
can avoid problems such as the build-up of noise and signal distortion during
processing. Since images are defined over two dimensions (perhaps more) digital
image processing may be modeled in the form of multidimensional
systems.
Many of the techniques of
digital image processing, or digital picture processing as it often was called,
were developed in the 1960s at the Jet Propulsion Laboratory, Massachusetts Institute of
Technology, Bell Laboratories, University of Maryland, and a few
other research facilities, with application to satellite
imagery, wire-photo standards conversion, medical
imaging, videophone, character recognition, and photograph
enhancement.[1]
The cost of processing was fairly high, however, with the computing equipment
of that era. That changed in the 1970s, when digital image processing
proliferated as cheaper computers and dedicated hardware became available.
Images then could be processed in real time, for some dedicated problems such
as television standards conversion. As
general-purpose computers became faster, they started to take over the role of
dedicated hardware for all but the most specialized and computer-intensive
operations.
With the fast computers and
signal processors available in the 2000s, digital image processing has become
the most common form of image processing and generally, is used because it is
not only the most versatile method, but also the cheapest.
Digital image processing
technology for medical applications was inducted into the Space
Foundation Space Technology Hall of Fame in 1994.[2]
Digital image processing allows
the use of much more complex algorithms, and hence, can offer both more
sophisticated performance at simple tasks, and the implementation of methods
which would be impossible by analog means.
In particular, digital image processing is the only
practical technology for:
Digital cameras generally
include dedicated digital image processing chips to convert the raw data from
the image sensor into a colour-corrected image in a standard image file format.
Images from digital cameras often receive further processing to improve their
quality, a distinct advantage that digital cameras have over film cameras. The
digital image processing typically is executed by special software programs
that can manipulate the images in many ways.
Many digital cameras also enable
viewing of histograms
of images, as an aid for the photographer to understand the rendered brightness
range of each shot more readily.
Multimedia
Applications: Multimedia is combination of text, graphics art, sound animation and
video elements. When you allow an end user to the viewer of a multimedia
project to control what and when the elements are delivered, it is interactive
multimedia. When you provide a structure of linked elements through which the
user can navigate, interactive multimedia becomes hypermedia.
Although the definition of multimedia is
a simple one, making it work can be complicated. The people who weave
multimedia into meaningful tapestries are multimedia developers.
The software vehicles, the messages, and
the content presented on a computer or TV screen together constitute a
multimedia project.
A multimedia project need not be
interactive to be called Multimedia: users can sit back & watch it just as
they do a movie or the TV. In such cases a project is linear, starting at a
beginning & running through to an end. When users are given navigational
control & can wander through the content at will, multimedia becomes nonlinear
& interactive & is a powerful personal gateway to information.
Multimedia elements are typically sewn
together into a project using authoring tool. These software tools are designed
to manage individual multimedia elements & provide user interaction. In
addition to provide a method for user to interact with the project, most authoring
tools also offer facilities for creating & editing text & images &
they have extensions to drive video disc players, video tape players &
other relevant hardware peripherals. Sound & movies are usually created
with editing tools dedicated system for playback. The some of what gets played
back & how it is presented to the viewer is GUI (pronounced “gooey”). This
interface is just as much the rules for what happens to the user’s input, as it
is actual graphics on the screen. The hardware & software that govern the
limits of what can happen are the multimedia platform or environment.
Use Of Multimedia:-
Multimedia is appropriate whenever a
human interface connects a human user to electronic information of any kind.
Multimedia enhances minimalist text-only computer interfaces & yields
measurable benefit by gaining & holding attention & interest;
multimedia improves information retention. When properly woven, multimedia can
also be profoundly entertaining.
Multimedia In Business:-
Business applications for multimedia
include presentations, training, marketing, advertising, product demos,
databases, catalogues &networked communications. Voice mail & video
conferencing will soon be provided on many local & wide area networks (LANs
& WANs) using Internet protocols.
After a morning of mind-numbing 35mm
slide & overhead presentations delivered from the podium of a national
sales conference, a multimedia presentation can make an audience come alive to
the usual “slide show” of graphics & text material.
Multimedia (MM) is enjoying widespread
use in training programs. Flight attendants learn to manage international
terrorism & security through simulation. Mechanics learn to repair engines.
Salespeople learn about product lines & leave behind software to train their
customers.
MM around the office has become more
commonplace. Laptop computers equipped with the fastest processors come
complete with CD-ROM drives & are ready for MM presentations on the road.
As companies & businesses catch on to
the power of MM, & the cost of installing MM capability decreases, more
applications will be developed both in-house & by third parties to allow
businesses to run more smoothly & efficiently.
Multimedia In Schools:-
Schools are perhaps the most needy
destination for multimedia. Many schools in the United States today are
chronically under funded & occasionally slow to adopt new technologies, but
it is here that the power of multimedia can be maximized for the greatest
long-term benefit to all.
In march 1995; the White House challenged
the telecommunications industry to connect every classroom, library, clinic,
& hospital to the information super highway by the year 2000. The White
House has also taken steps to provide governmental support for state-of-the-art
technology in low-income rural & urban school districts.
MM will provoke radical changes in the
teaching process during the coming decades, particularly as smart students
discover they can go beyond the limits of traditional teaching methods. Indeed,
in some instances, teachers may become more like guides & mentors along a
learning path, not the primary providers of information & understanding-
the students, not teachers become the core of the teaching & learning
process. This is a sensitive & highly politicized subject among educators,
so educational software is often positioned as “enriching” the learning
process, not as a potential substitute for traditional teacher-based methods.
An interesting use of MM in schools
involves the students themselves. Students put together interactive magazines
& newsletters, they make original art using image-editing tools, they
interview students & townspeople & coaches & teachers, & they
make QuickTime movies. They design &run Web sites.
Multimedia At Home:-
From gardening to cooking to home design,
remodeling, & repair to genealogy software, MM has entered the home. Eventually,
most MM projects will reach the home via television sets or monitors with
built-in interactive user inputs-either on old-fashioned color TVs or new high
definition sets. The MM viewed on these sets will likely arrive on a
pay-for-use basis along the data highway.
Today, home consumers of MM either own a
computer with an attached CD-ROM drive or a set-top player that hooks up to the
television, such as Sega or Nintendo or Sony game machine. There is increasing
convergence of computer-based MM with entertainment & game-based media traditionally
described as “shoot-em-up”. Nintendo alone has sold over 100 million game
players worldwide & more than 750 million games.
Live Internet pay-for-play gaming with
multiple players has become popular, bringing MM to homes on the data highway,
often in combination with locally inserted CD-ROMs. Microsoft’s Internet Gaming
Zone &Sony’s Station Web site boast more than a million registered users
each – Microsoft claims to the most successful, with tens of thousands of
people logged on & playing every evening.
The home of the future will be very
different when the cost of computer hardware & MM televisions becomes
mass-market affordable & the MM connection to the data highway is widely
available. When the number of MM households increases from hundreds of
thousands to many millions, a vast selection of MM titles & material will
be required to satisfy the demands of this market, & vast amounts of money
will be earned producing & distributing these MM products.
Multimedia In Public Places:-
In hotels, train stations, shopping
malls, museums, & grocery stores, MM will become available at stand-alone
terminals or kiosks to provide information & help. Such installations
reduce demand on traditional information booths & personnel, add value,
& they can work round the clock, even in the middle of the night, when live
help is off duty.

supermarket a kiosk that provides service ranging from meal planning to
coupons. Hotel kiosks list nearby restaurants, maps of the city, airline
schedules, & provide guest services such as automated checkout. Printers
are often attached so users can walk away with a printed copy of the
information. Museums kiosks are not only used to guide patrons through the
exhibits, but when installed at each exhibit, provide great added depth,
allowing visitors to browse through richly detailed information specific to
that display.
The power of MM has been part of the
human experience for many thousands of years.
Virtual Reality:-
At the convergence of
technology & creative invention in MM is virtual reality, or VR. Goggles,
helmets, special gloves & bizarre human interfaces attempt to place you
“inside” a lifelike experience. Take a step forward, & the view get closer,
turn your head, & the view rotates. VR requires terrific computing horsepower
to be realistic. In VR, your cyberspace is made up of many thousands of
geometric objects plotted in 3-dimensional space; the more objects & the
more points that describe the objects, the higher the resolution & the more
realistic view. As you move about, each motion or action requires the computer
to recalculate the position, angle, size, & shape of all the objects that
make up your view, & many thousands of computation must occur as fast as 30
times per second to seem smooth.
On the World Wide Web, standards
for transmitting virtual reality worlds or “scenes” in VRML (Virtual Reality
Modeling Language) documents (with the file name extension .wrl) have been
developed. Intel & software makers such as Macromedia & Adobe have announced
support for new 3-D technologies.
Need Of Multimedia:-
We need
hardware & software & good ideas to make MM. To make good MM, we need
talent & skill. You also need to stay organized, because as the
construction work gets under way, all the little bits & pieces of MM
content. We will need time & money (for consumable resources such as disks
& other memory, for telephoning & postage, & possibly for paying
for special services & time, yours included), & you will need to budget
these precious commodities.
We will also
need the help of other people. MM is often a team effort: graphic artists
perform artwork, video shoots by video producers, sound editing by audio
producers, & programming by programmers.
Space
Research: "Every day" technologies such
as weather forecasting, remote
sensing, GPS
systems, satellite television, and some long distance
communications systems critically rely on space infrastructure. Of sciences, astronomy and
Earth
sciences (via remote sensing) most notably benefit from space
technology.
Computers and telemetry
were once leading edge technologies that might have been considered "space
technology" because of their criticality to boosters and spacecraft.
They existed prior to the Space Race of the Cold War
(between the USSR and the USA.) but their development was vastly accelerated to
meet the needs of the two major superpowers' space programs. While still used
today in spacecraft and missiles, the more prosaic applications such as remote
monitoring (via telemetry) of patients, water plants, highway conditions, etc.
and the widespread use of computers far surpasses their space applications in
quantity and variety of application.
Space is such an
alien environment that attempting to work in it requires new techniques and
knowledge. New technologies originating with or accelerated by space-related
endeavors are often subsequently exploited in other economic activities. This
has been widely pointed to as beneficial by space advocates and enthusiasts
favoring the investment of public funds in space activities and programs.
Political opponents counter that it would be far cheaper to develop specific
technologies directly if they are beneficial and scoff at this justification
for public expenditures on space-related research.
Without the advancement of computer technology
we would not have the Hubble Space Telescope in space. From analyzing data
gathered by these telescopes, to designing the complex systems needed to make
them work, computer technology goes hand in hand with the advancement of space
research.
Computer
Uses
Early astronomers studied space from the
limited view of their telescopes. Now, astronomical data from around the world
is overflowing, thanks to the powerful tool called the computer.
The possible uses of a computer for space research are limited
only by your imagination. Space simulations, data visualization, rover or robot
manipulation, complex calculations and signal transmissions are some of the
many ways that a computer aids astronomy.
Data
Analysis and Documentation
Data analysis and documentation is perhaps the most apparent use
of computers for space research. With piles of research data, astronomers need
a way to store and share information conveniently.
Computers facilitate faster flow of information by providing
collaborative workspaces.
In 1992, the Information Systems Branch of Kennedy Space Center
developed a special computer software, based on the Windows Visual News Reader
or Win Vn application, that helped organize loads of technical space
information and allowed various space groups to exchange ideas
