what are network

What are network? A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.

A network allows sharing of files, data, and other types of information giving authorized users the ability to access information stored on other computers on the network. Distributed computing uses computing resources across a network to accomplish tasks.

Setting up a computer network is a fast and reliable way of sharing information and resources within a business. It can help you make the most of your IT systems and equipment.

Main benefits of networks include:

·         File sharing – you can easily share data between different users, or access it remotely if you keep it on other connected devices.

·         Resource sharing – using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money.

·         Sharing a single internet connection – it is cost-efficient and can help protect your systems if you properly secure the network.

·         Increasing storage capacity – you can access files and multimedia, such as images and music, which you store remotely on other machines or network-attached storage devices.
