Computer networks permit multiple computers and devices to communicate and share information and resources. This lets businesses communicate more effectively, improve productivity, and provide better customer service. A computer network consists of two main components, nodes or devices and links. Nodes are devices that communicate, like computers, mobile devices and printers, while links are physical connections that transfer data between them. These links comprise cables, fiber optics, and wireless signals such as Wi-Fi. Data is transmitted from one node to the next with a set pre-programmed rules, referred to as communication protocols.
Some of the advantages of computer networking are:
The most obvious benefit of computers is the ability to share hardware and software resources. For example, a network can allow multiple employees to use the same scanners and printers. This helps to cut costs and boost productivity by allowing work to be completed without the requirement for each employee to own their own equipment. It also allows for the sharing of documents in a simple manner, which can make processes easier in areas like project collaboration and recording. Additionally, the use of computer networks allows companies to manage and control huge amounts of information. This can be beneficial for businesses such as marketing, banking, and insurance.
