To Computer Networking
Networking is linking two or more computers with each other.
The connectivity can be wired or wireless.Computer Networking
is divided in to Local Area Network (LAN), networking between
computers in a same office,building,home etc.Wide Area Network
(WAN) networking between the computers, one is locally placed
and the other can be thousands of miles away in another city
or another country in the world.WAN connectivity is achieved
by a device known as “Router”. The internet is
the world’s largest WAN, where millions of computers
from all over the globe are connected with each other.
are two main types of the computer networking client-server
and peer to peer. In the client server computing, a computer
plays a major role known as server, where the files, data
in the form of web pages, docs or spread sheet files, video,
database & resources are placed.All the other computers
in the client/server networks are called clients and they
get the data from the server. In the peer to peer networks
all the computers play the same role and no computer act as
a centralized server. In the major businesses around the world
client-server networks model is in major use.
the computer age, no organization can work perfectly without
a computer network. The concept and working of the whole internet
is due to the computer networking. A computer network is a
basic need for any organization to share data and resources
on the small to big level such as banks, insurance companies,
universities, colleges, multinational companies, corporate
offices and small businesses etc. The network is made up of
different components, protocols, devices, topologies and mediums
such as cables, routers, leased lines and air.
Networking can be wireless or cabled. In a cabled network,
there are a certain types of the cables required depending
on the type of the network. The most commonly used cables
are the UTP/STP .Ethernet cables also known as CAT5 cables.
In the CAT5 cables, there are eight cables and four pairs.
Each cable is twisted with its corresponding cable and thus
forms a pair. From these eight cables, there are two major
types of cables are formed known as straight over cable and
cross over cable. A straight over cable is used to connect
a computer with a hub or switch and a cross over cable is
used to connect the computers with each other and to connect
the communication devices with each other such as routers,
switches and hubs.
