What is Computer Network?
A computer
network is a group of computers,
printers, and other devices that are connected
together with cables. Information travels over the
cables, allowing network users to exchange
documents & data with each other, print to the
same printers, and generally share any hardware or
software that is connected to the network. Each
computer, printer, or other peripheral device that
is connected to the network is called a
node. Networks can have tens,
thousands, or even millions of nodes.
Like
most things, networks are are assembled according
to certain rules. Cabling, for example, has to be
a certain length, each cabling strand can only
support a certain amount of network traffic, etc.
The rules that govern how a network is set up is
called its topology. The most popular topology in use
today is called Ethernet, which
consists of computers and peripherals cabled
together in specific ways. Ethernet is relatively
inexpensive, easy to set up and use, and very,
very fast.
