Computer networks connect multiple devices and computers to one and allow them to share resources and information. This allows companies to communicate more effectively and improve productivity. It also allows them to offer better service to their customers. A computer network is composed of two fundamental components: nodes or devices and links. Nodes are devices used for communication, such as mobile devices, computers, and printers, and links are physical connections that transmit information between them. These connections include cables, fiber optics and wireless signals such as Wi-Fi. Data is sent from one node (or device) to another through an established set of pre-programmed communication protocols.
Computer networking can bring many benefits.
The most obvious benefit of computer networks is the ability to share hardware and software resources. For example, a network could allow multiple employees to use the same printers and scanners. This can reduce costs and increase productivity because every employee does not have to have their own equipment. It allows for easy document sharing, which can simplify processes such as collaboration for projects and record-keeping. Additionally, the use of computer networks allows organisations to manage and control huge amounts of data. This can be beneficial for industries like banking, insurance, and marketing.
