Computer networks enable multiple devices and computers to communicate with each other and share resources and information. This allows businesses to communicate more effectively, improve productivity, and provide better customer service. A computer network is comprised of two fundamental components: nodes or devices and links. Nodes are devices for communication such as mobile devices, computers and printers, and links are physical connections that transmit information between them. These links are made up of fiber optic cables, cables and wireless signals like Wi-Fi. Data is transferred from one node (or device) to another by using a set pre-programmed communication protocols.

Some of the benefits of computer networking are:

The most obvious benefit of computer networks is the ability to share hardware and software resources. For instance, a network can permit multiple employees to access the same scanners and printers. This helps to cut costs and increases productivity by allowing work to be completed without the need for each employee to have their own equipment. It makes it easy to share documents sharing, which can simplify processes such as project collaboration and recording. Using computer networks also makes it easier for businesses to manage and control large amounts of data. This can be beneficial to industries like banking, insurance and marketing.
