Computer networks connect multiple devices and computers to each with the ability to share resources and information. This allows businesses to communicate more efficiently and improve productivity. It also allows them to offer better customer service. A computer network is comprised of two main components: nodes or devices, and links. Nodes are devices for communication like mobile devices, computers, and printers, while links are physical connections that transfer information between them. These links comprise fiber optics, cables and wireless signals like Wi-Fi. Data is transmitted from one node (or device) to another via a set pre-programmed communication protocols.

Computer networking offers many benefits.

The most obvious benefit of computer networks is the capacity to share software and hardware resources. A network allows many employees to share the same scanners or printers. This helps reduce costs and improves productivity because each employee does not need to own their own equipment. It also facilitates document sharing, which helps to simplify processes like collaboration on projects and keeping records. Furthermore, the use of computer networks allows companies to manage and control huge amounts of data. This is beneficial for businesses such as banking, insurance and marketing.
