A client may refer to any of the following:
1. A client is a computer that connects to and uses the resources of a remote computer, or server. Many corporate networks comprise a client computer for each employee, each of which connects to the corporate server. The server provides resources like files, information, Internet and intranet access, and external processing power. In the case of processing, any work done on the server is referred to as "server-side" work. Any work done on the local client is similarly called "client-side."
The following example compares a client-side script and a server-side script, and explains how a client computer interacts with an Internet server.
3. A client can also be another term used to describe a user.
