Hi
Under the structure of the client-server architecture, a business's computer network will have a server computer, which functions as the "brains" of the organization, and a group of client computers, which are commonly called workstations. The server part of the client-server architecture will be a large-capacity computer, perhaps even a mainframe, with a large amount of data and functionality stored on it. The client portions of the client-server architecture are smaller computers that employees use to perform their computer-based responsibilities.
Servers commonly contain data files and applications that can be accessed across the network, by workstations or employee computers. An employee who wants to access company-wide data files, for instance, would use his or her client computer to access the data files on the server. Other employees may use a common-access application by accessing the server through their client computers.
This type of server is called an application server. It takes full advantage of the client-server architecture by using the server as a storage device for applications and requiring the clients to log in to the server in order to use those applications. Examples of this kind of application are numerous; among the most popular are word processors, spreadsheets, and graphic design programs. In each case, the use of the applications illustrates the client-server architecture.
Thanks
