You can say N here if you don't intend to connect your Linux box to

any other computer at all.

You'll have to say Y if your computer contains a network card that
|
you want to use under Linux. If you are going to run SLIP or PPP over
|
telephone line or null modem cable you need say Y here. Connecting
|
two machines with parallel ports using PLIP needs this, as well as

configure. See www.wireguard.com for more info.
