To configure means to set up for operation in a certain way. Desktop machines need to be configured, or set up in a certain way, when you switch your ISP or when you add a new machine to the network. The process is basically the same for each circumstance. If you connect to the Internet through a modem, your system might be configured automatically based on information supplied by your ISP. If you connect to the Internet through a network, you may have to configure your system manually. The system administrator should supply you with the necessary information.
Configuring the desktop involves modifying some or all of the following:

1. TCP/IP settings
2. HOSTS files
3. Browsers
4. Email
5. MIME settings

TCP/IP is:

1. A generic name for a suite of protocols used to connect computers and networks
2. The protocol used to connect to the Internet

The Transmission Control Protocol (TCP) is used to transfer the IP-formatted data packets. The Internet Protocol (IP) is the set of rules used to pass packets of data from one network to another.

To configure TCP/IP on a Macintosh, from the Apple menu, select Control Panels, then select TCP/IP. The settings shown in the table below appear. For information about the settings to use for your system, talk with your system administrator or ISP.
