What is network
Networking is one of the
most significant steps in the electronic evolution since the invention of the
PC. A computer network is a group of connected computers that allow the sharing
of information and peripherals. The most basic network is made up of two
computers connected by some kind of cable in order to exchange information more
quickly and efficiently. A standalone computer is very useful to many
businesses, but without a network, those businesses would have to spend twice
the amount of money on computerization than they would have to by implementing
a network
A network allows many
computers to share peripheral devices such as printers and facsimile machines.
The two primary benefits of computer networks are sharing of devices and data.
There are two basic types of networks: peer-to-peer and server-based. On a
peer-to-peer network, any computer can act as a server to share resources with
other machines and as a client to access these resources. On the other hand,
server-based networks require a server computer whose job is to respond to
requests for services or resources from clients elsewhere on the network.
Server-based networks are used in most organizations today.
Servers can also be very
expensive, ranging from $5000.00 to $150,000.00.There is an advantage to
server-based networks such that it centralized user accounts and easy
maintenance with less need for administration. There are some disadvantages as
well. Two of the largest and most common disadvantages are server failure and
initial start up cost. (word 246)
