Description

You can say no here if you do not intend to connect your Linux box to any other computer.

You'll have to say yes if your computer contains a network card that you want to use under Linux. If you are going to run SLIP or PPP over a telephone line or null modem cable you need say yes here. Connecting two machines with parallel ports using PLIP needs this, as well as AX.25/KISS for sending Internet traffic over amateur radio links.
