Computer networks enable multiple devices and computers to communicate with each other and share information and resources. This allows businesses to communicate more efficiently, increase productivity, and offer better customer service. A computer network is composed of two basic components, devices or nodes, and links. Nodes are devices that communicate, such as mobile devices, computers and printers, while links are physical connections that transfer information between them. These connections include fiber optics, cables and wireless signals, such as Wi-Fi. Data is transferred from one node (or device) to another via an established set of pre-programmed communication protocols.
Computer networking can bring many benefits.
Computer networks are most beneficial when they allow users to share hardware and software resources. A network allows multiple employees to share the same printers or scanners. This reduces expenses and increases productivity by enabling work to be completed without the requirement for each employee to own their own personal equipment. It also permits the easy sharing of documents, which can streamline processes in areas like project collaboration and record keeping. Computer networks can make it easier for businesses to manage and manage large volumes of data. This is beneficial in industries like marketing, banking, and insurance.
