Clients

Clients
Remember, all computers on the Internet (a wide area network, or WAN) can be lumped into two groups: servers and clients, which communicate with one another.
Independent computers connected to a server are called clients. Most likely, your home or office computer does not provide services to other computers. Therefore, it is a client.
Clients run multiple client software applications that perform specific functions.
For example,
An email application such as Microsoft Outlook is client software.
Your web browser (such as Internet Explorer or Netscape) is client software.
