The NIC must be configured at boot time with many networking parameters, such as an IP address and mask. In addition your host will need a default gateway address to configure its routing table. To use DNS your computer must be assigned a hostname, a default domain name, and must be configured with the IP address of at least one DNS server to use to translate names to IP addresses.
The easiest way to configure TCP/IP networking is to let someone else do it. One way to achieve this is to configure your system to use DHCP (dynamic host configuration protocol) for each NIC. When the system brings up the NIC (usually at boot time) it will send a broadcast DHCP request packet. If there is a DHCP server listening on that LAN, it will respond with (hopefully) all the required networking parameters.
The other way to configure networking parameters is manually editing various configuration files (or using some tool to edit those files). This is called static addressing.

To configure the system for DHCP this file should look
something like this:
# Intel Corporation 82557/8/9 [Ethernet Pro 100] DEVICE=eth0 HWADDR= =00:06:5B:3E:89:0F ONBOOT=yes BOOTPROTO=dhcp
This will cause the network system to configure everything using DHCP. For a static setup, this file should look like this:
# Intel Corporation 82557/8/9 [Ethernet Pro 100] DEVICE=eth0 HWADDR= =00:06:5B:3E:89:0F ONBOOT=yes BOOTPROTO=static IPADDR=192.168.0.7 NETMASK=255.255.255.0 GATEWAY=192.168.0.4
That will configure the IP address and mask,
and the default route, but not DNS.
