The Client/Server Network
In the client/server network, a main computer that contains all the files and services is known as a server; all other computers are known as clients. In this network model, every client residing on the network shares the resources of the server. This network model allows client computers to access information, resources, and services located on the server computer.
As a term implies, the client/server network includes two basic components:
A client request a service, which might be to run an application, query database, print a document, or even perform a backup or recovery procedure. A server handles the request of a client. today, networks may have the File, Database, and Application servers where each server is dedicated to provide a specific service to all the users within a network. Servers are generally high-performance computers, optimized to provide network services to other computers.
