Apple 6400 appendix Installing a communication card

Installing a communication card

This section contains instructions for installing an Ethernet or internal modem card in the communication slot in your computer. You use an Ethernet card to communicate with other computers through a local area network. For example, in businesses, it is what enables more than one computer to print on a shared printer and to access documents on a central, shared server.

Note: Using a modem is not the same as being connected to a local area network. If you have an internal modem and the appropriate software that makes use of it, you already have access to online services. You do not need an Ethernet card unless you need to connect your computer to other computers in an Ethernet network. For more information about connecting to an Ethernet network, see “Connecting to an Ethernet Network” in Chapter 8.
