Installing a communication card
This section contains instructions for installing an Ethernet or an internal
modem card in the communication slot. You use an Ethernet card to
communicate with other computers through a local area network (LAN). For
example, in businesses, an Ethernet card connected to a LAN 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. 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 the section “Connecting to a Network” in Chapter 3.
Some communication cards designed for other communication slots are not
compatible and cannot be installed here. You can tell by examining the
placement of the notches on the card. Use the following illustration as a guide
if you’re not sure you have the correct type of card.
