Computer networks allow multiple computers and devices to communicate and share information and resources. This lets businesses communicate more efficiently, increase productivity, and provide better customer service. A computer network is made up of two primary components, nodes or devices and links. Nodes are communication endpoints, such as computers, printers and mobile devices, and links are the physical connections that transport data between them. These links comprise fiber optics, cables and wireless signals such as Wi-Fi. Data is transferred from one device (or device) to another by using pre-programmed communication protocols.

Some of the main benefits of computer networking are:

The primary benefit of computer networks is the ability to share hardware and software resources. For example, a network can allow multiple employees to access the same printers and scanners.
