What Is A Server ?

Definition: A network server is a computer designed to process requests and deliver data to other (client) computers over a local network or the Internet. 

Network servers typically are configured with additional processing, memory and storage capacity to handle the load of servicing clients. Common types of network servers include:

• Web servers
• proxy servers
• FTP servers
• online game servers

Numerous systems use this client / server networking model including Web sites and email services. An alternative model, peer-to-peer networking enables all computers to act as either a server or client as needed.
