What is computer network?

A computer network is a collection of interconnected devices, such as computers, servers, routers, switches, and other networking equipment, that are linked together to facilitate communication and data sharing between them. It allows the devices to exchange information and resources, such as files, documents, printers, and internet access, either within a local area (LAN) or across a wide area (WAN). Computer networks can be wired or wireless, and they enable individuals and organizations to connect and collaborate efficiently.
