Computer networks enable multiple devices and computers to communicate and share information and resources. This lets businesses communicate more efficiently, increase productivity, and provide better customer service. A computer network is made up of two main components, nodes or devices, and links. Nodes are communication devices like computers, mobile devices and printers, while links are physical connections that transmit data between them. They include cables, fiber optics, and wireless signals such as Wi-Fi. Data is transmitted from one node to the next through a set of pre-programmed protocols, also known as communication protocols.
Some of the benefits of computer networking include:
Computer networks are the most effective when they permit users to share hardware and software resources. For instance, a computer network can permit multiple employees to use the same printers and scanners. This can help cut costs and boost productivity by allowing work to be completed without the requirement for each employee to have their own personal equipment. It allows for easy document sharing, which could simplify processes like collaboration on projects and record-keeping. Furthermore, the use of computer networks allows companies to manage and control large amounts of data. This is beneficial for industries such as marketing, insurance, and banking.
