Computer networks allow multiple computers and devices to communicate with each other and share resources and information. This enables companies to communicate more effectively, improve productivity and offer better service to their customers. A computer network is made up of two main components, devices or nodes, and links. Nodes are devices that communicate, such as mobile devices, computers, and printers, while links are physical connections that transmit information between them. These connections include cables, fiber optics, and wireless signals like Wi-Fi. Data is transferred from one point to another through a set of pre-programmed rules called communication protocols.

The main benefits of computer networking include:

The most obvious benefit of computer networks is the ability to share software and hardware resources. A network permits multiple employees to share the same printers or scanners. This can reduce costs and increase productivity since every employee does not have to own their own equipment. It allows for easy document sharing, which can streamline processes like collaboration on projects and keeping records. Furthermore, the use of computer networks makes it easier for organisations to manage and control large amounts of data. This can be advantageous for industries such as marketing, banking, insurance and banking.
