Introduction to computer networking

A simple network
Computer networking is one of the most efficient ways of using resources. Networking allows the sharing of limited resources like printer, scanner, files and many others. It can be very beneficial to businesses on limited budget. Home users can also take advantage of this technology very easily.

But what is computer networking? Networking is simply the linking of computers and other devices together to enable the sharing of resources. Todays networking involves connecting computers, laptops, mobiles phones, tablets and other devices.

There are basically two ways by which this process can be achieved namely: client server technology and peer to peer network. Personally, I favour client server technology because it offers better security. Peer to peer network is however, very easy to setup and requires less overhead.

Choosing a network therefore, depends on the users particular need. If the object is just to share resources within a single office then peer to peer may be the way to go. However, if security is going to be a major concern particularly where resources are distributed in different locations, then client server technology must be the ideal choice.

Devices and computers can be linked together via wireless technology or wired technology. And it is the wireless technology that makes it easy for devices like tablets and mobile phones to partake in networking.

Choosing a network also involves choosing a topology. And anyone of these  topologies: wan, lan, star, bus and met could be used. But again, it is dependent on need and preference.

Below is a simple diagram of a network.
