Computer networks enable multiple devices and computers to communicate and share information and resources. This allows businesses to communicate more efficiently and improve productivity. It also allows them to provide better service to clients. A computer network consists of two primary components, devices or nodes, and links. Nodes are communication devices, such as computers, printers and mobile devices, whereas links are the physical connections that transmit data between them. These connections include cables, fiber optics and wireless signals such as Wi-Fi. Data is transmitted from one node to another by using a set of pre-programmed rules, referred to as communication protocols.
Computer networking offers many benefits.
Computer networks are the most effective when they allow users to share hardware and software resources. A network permits several employees to share the same scanners and printers. This helps to cut costs and increases productivity by enabling work to be completed without the requirement for each employee to have their own equipment. It allows for easy document sharing, which helps to simplify processes such as project collaboration and record-keeping. Using computer networks also makes it easier for companies to manage and control large volumes of data. This is beneficial for industries like marketing, banking, and insurance.
