Networks For People:-
The Motivation given above for building for computer networks are all essentially economics and
technological in nature. if sufficiently large and powerful mainframes were available at acceptale
prices most company would simply choose to keep all there data on them and give employees
terminals connected to them. in the 1970s and early 1980s, most companies operated this way.
comfferd a huge price/performance advantage over mainframes..
Starting in the 1990s, computer network began to start delivering service to private individuals
at home. these service and the motivation for using them are quite defferent then the "corporate
efficiency" model described in the previous section below we will sketch three of the more exciting ones that are that starting to happen.

1-Acces to remote information
2-Person to Person communication
3-Interactive entertainment
Access to remote information will come in many forms. One area in which it is already happening
is access to financial institution. Many people pay there bills, manage there bank accounts, and
handle there investment electronically. Home shopping is also becoming popular, with the ability
to inspect the online cat-logs of thousands of companies some of these catlogs will soon provide the ability to get an instant video an any product by just clicking on the product`s name.
Newspaper will go online and personalized. It Will be possible to tell the newspaper that you
want everything about corrupt polticians big fires, scandals invobing celebrities, and epidemics, but
no football, thank you at night while you sleep the newspaper will be downloaded to your
computers disk or printed on your laser printer on a small scale this service already exists.the
next step beyond newspaper (plus magazines and scientific journals) is the on-line digital library.
depending on the coast, size, and weight of book-sized notebook computers, printed books may
become obsolete. skeptics should take notes of the effect the printing press had on the medieval illuminated manuscipet.
Another application that falls in this category is access to information systems like the current
world wide web, which contains information about the art business, cooking, government, health,
history, hobbies, recreation, science, sports, travel, and too many other topics to even mention.
All of the above applications involve interactions between a person and a remote database. the
second board category of network use will be person-to-person interaction, basically the 21st
century answer to the 19th century tele-phone. Electronic Mail or Email is already widely used by
millions of people and will soon routinely contain audio and video as well as text. smell in messages will take a bit longer a perfect.
Real-time email will allow remote users to communicate with no delay, possibly seeing and
hearing each other as well as. this technology makes it possible to have virtual meetings, called
video conference, among far-flung people. it is sometimes said that transportation and
communication are having a race, and which ever wins will make the other obsolete. virtual
meetings could be used for remote school, getting medical opinions from distant specialists, and numerous other applications.
Worlwide newsgroups, with discussions on every conceivable topic are already commonplace
among a select group of people, and this will grow to including the population at large. these
disussions, in which one person posts message and all the other subscribers to the newsgroups can
read it, run the gamut from humorous to impassioned.
Our third category is entertainment, which is a huge and growing industry. The killer applications
here (the one that may drive all the rest) is video on demand. a decade or so hence, it may be
possible to select any movie or televisions program ever made, in any country, and have it
displayed on your screen instantly. New films may become interactive, where the users is
occasionally prompted for the story direction (should macbeth murder Duncan or just bide his
time) with alternative scenarios provided for all cases. live television may also become interactive, with the audience participting in quiz shows, choosing among contestant, and so on.
On The Other Hand, May be the killer application will not be video on demand maybe it will be
game playing. already we have multiperson real time simulaton games, like hide and seek in a
virtual dungeon, and flight simulators with the players on one team trying to shoot down the
players on the opposing team.I done With Goggles and three dimensional real time, Photogaphics-
quality moveing images, we have a kind of wordwide shared virtual reality.
In Short, The ability to merge information, communication and entertainment will surely give rise
to a massive new industry based on computer networking.
