If you are running a small business, or even if you have more than one computer at home, you'll get more out of your investment with your computers connected into a Local Area Network (LAN).

The required hardware and software has become more affordable, easier to use, and faster in speed. So you really have no excuse!

Networks enable groups, departments and entire enterprises to share information and work as a team. As organizations grow, structures change; groups form and reform, and many IT managers are left struggling to adapt networks to connect everyone throughout the enterprise. Networks vary in size: some are within a single office, others span the globe.

What is a Network?

A computer network is a collection of PCs and other devices connected together with cables, so that they can communicate with each other for the purpose of sharing information and resources.

How does a Network Work?

Devices on a network communicate by transmitting information to each other in groups of small electrical pulses (known as packets). Each packet contains address information about the transmitting device (the source address) and the intended recipient (the destination address). This address information is used by some of the network equipment to help the packet reach its destination.

What Are The Benefits of Networking?

Creating a network, by connecting computer equipment together, permits the equipment to communicate and share information and resources. In particular, you can:

Share expensive peripherals, such as printers — All of the computers can access the same printer.
Pass data between users without the use of floppy disks — Files can be copied and accessed across the network, eliminating the time wasted and inconvenience caused by using floppy disks to transfer files. There is also less restriction on the size of file that can be transferred over the network.
Centralize key computer programs, such as finance and accounting programs — It is often important that all users have access to the same program (and not copies of it) so that they can work on it simultaneously (for example, a ticket booking application where one program must be used to ensure that the same tickets are not sold twice). Networking allows offices to have such a central program that all users can access.
Automate backup of critical files — It is always essential to keep backups of any important files. You can automate this procedure by having a computer program that backs up the files for you. Without a network, you would have to manually copy files, which is time consuming.
