Many organizations have large number of substantial computers in operation often located far apart. Let us consider an example, a company having many factories situated at different locations. A computer at each location (that is in each factory) keeps the track of inventories, monitor productivity and do the local pay roll. Initially each of these computers may have worked in isolation from each other, but at some point, the management may have decided to connect these computers to be able to extract and correlate the information of the entire company.
The issue here is resource sharing. Its goal is to make all the programs, equipments, especially data available to anyone on the network irrespective of the location of the resource and the user.
2.High Reliability:
The second goal or use of networking in companies is to high reliability by having alternative sources of supply. For example all the files can be replicated on two or more machines, so that in case one of them is not available (due to hardware failure), other copies can be used. This feature is used in financial institutions.
.3.Saving Money:
The third goal is to save money. Small computers often have better price/performance ratio than the larger ones. Mainframe (room-size) computers are roughly ten faster than the personal computers, but are a thousand times costly. This imbalance caused the system designers to design a system consisting of personal computers, one per user, with data kept on one or more shared file server machines. In this model the user are called the clients and this whole arrangement is known as the client-server model.
In client-server model, the communication generally takes the form of a request message from a client to the receiver asking for some work to be done. Server does the work and sends back the reply.
4.Scalability:
Another goal is scalability. Scalability is the ability to increase the system performance gradually as the workload grows, by just adding more processors.
Uses of Networks to People
1.Access to Remote Information:
Access to remote information occurs in many forms. One of the areas where it is happening is access to the financial institutions. Many people pay their bills, manage bank accounts and handle investments electronically. Home shopping is also becoming popular these days.
Another application that falls under this category is the access to information systems like World Wide Web which contains information about art, business, history, government, geography, economics and several other topics.
All the above applications involve the interaction between the user and a remote database.
2.Person to Person Communication:
Electronic Mail popularly known as email is widely used by millions of people to send text messages, photographs audio as well as video to other people or group of people. This application belongs to person to person communication category.
Videoconferencing is also becoming popular these days. This technology makes it possible to have virtual meetings among far flung people. It is also a type of person to person communication.
