Computer networks enable multiple devices and computers to communicate and share information and resources. This enables businesses to communicate more efficiently, improve productivity and offer better customer service. A computer network is made up of two primary components, nodes or devices and links. Nodes are the communication endpoints such as printers, computers and mobile devices, while links are the physical connections that transport data between them. These links include fiber optics, cables and wireless signals like Wi-Fi. Data is transferred from one node to the next with a set pre-programmed rules called communication protocols.
Some of the main benefits of computer networking are:
Computer networks are the most effective when they permit users to share software and hardware resources. A network permits many employees to share the same printers or scanners. This lowers costs and boosts productivity since employees do not need to have their own equipment. It facilitates document sharing, which helps to simplify processes such as collaboration for projects and record-keeping. Using computer networks also makes it easier for companies to manage and control large amounts of data. This can be beneficial for industries like banking, insurance and marketing.
