NIC |
A
Network Interface Card allows your computer to connect to
a network of computers. The most common type of NIC is ethernet
- a very fast method of transferring data between computers.
A modem is generally used to dial-up from a home computer
to connect to a network or the Internet. However, an ethernet
NIC uses a cable that usually connects to a hub which connects
to a router which connects to a switch, and these pieces are
also often connected to a server through the same type of
cable and to the Internet backbone via a fiber optic cable.
The NIC allows the computer to share with and get resources
from other computers on the network (as well as the Internet
if it is not a Local Area Network (LAN). A LAN is a closed
network consisting of 2 or more computers that are connected
through NICs and hubs, generally not connected to the outside
world - the Internet. Hubs allow several computers to share
one cable connection (1 cable connects to another hub or router,
and the hub provides 5 (more or less) connections for other
computers or hubs to connect to). |
