Computer networks permit multiple computers and devices to communicate and share resources and information. This lets businesses communicate more efficiently, increase productivity, and offer better customer service. A computer network is composed of two basic components: nodes or devices and links. Nodes are communication endpoints, such as printers, computers and mobile devices, whereas links are the physical connections that transfer information between them. These links include fiber optics, cables and wireless signals such as Wi-Fi. Data is transmitted from one device (or device) to another by using pre-programmed communication protocols.

Some of the main benefits of computer networking are:

Computer networks are most useful when they permit users to share software and hardware resources. A network allows multiple employees to share the same printers or scanners. This helps to cut expenses and increases productivity by enabling work to be completed without the need for each employee to have their own personal equipment. It also facilitates document sharing, which can simplify processes like collaboration on projects and recording. Using computer networks also makes it easier for companies to manage and manage large volumes of data. This is beneficial in industries like marketing, banking, insurance and banking.
