The network provides access to a wide collection of resources. Most
computers today connect to the network either through an Ethernet
network card or else by modem. Once connected you have an IP address
(and sometimes more than one) assigned to your computer by which all
communications is effected. IP addresses are sequences of numbers.
Two things need to happen to get your network going: loading a driver
for your network card and specifying your network address and
configuration.
An Ethernet based network is usually started up at boot time by the
system initialisation script /etc/init.d/networking. For
pcmcia
network cards the /etc/pcmcia/ tree
provides its own scrips, including /etc/pcmcia/network, that
is called whenever a network card is found in the PCMCIA socket.
