Servers are special, powerful computers that provide ‘services’ to the
client computers on the network.

These services might include:

• Providing a central, common file storage area

• Sharing hardware such as printers

• Controlling who can or can’t have access the network

• Sharing Internet connections

Client-Server Architecture


An architecture in which the user's PC (the client) is the requesting machine,
 and the server is the supplying machine, both of which are connected via a local area network (LAN)
 or a wide area network (WAN) such as the Internet.
