Computer networks permit multiple computers and devices to communicate with each other and share resources and information. This allows businesses to communicate more effectively, improve productivity, and offer better customer service. A computer network consists of two primary components: nodes, or devices and links. Nodes are devices used for communication, such as mobile devices, computers and printers, while links are physical connections that transfer data between them. These connections include cables, fiber optics, and wireless signals such as Wi-Fi. Data is transmitted from one node to another by using a set of pre-programmed rules known as communication protocols.

Some key advantages of computer networking are:

The most obvious benefit of computer networks is the ability to share hardware and software resources. A network allows multiple employees to use the same scanners or printers. This can reduce costs and increase productivity because every employee does not have to own their own equipment. It facilitates document sharing, which can simplify processes like collaboration on projects and keeping records. Computer networks also make it easier for companies to manage and manage large volumes of data. This can be beneficial in industries like marketing, insurance, and banking.
