What is computer networking?

Computer networking refers to the practice of connecting computers and other devices together so they can communicate and share resources, such as files, printers, and internet access. This can involve local networks within a single building (LANs) or larger networks that span cities or even countries (WANs). Networking relies on hardware like routers and switches, as well as software protocols that ensure reliable communication and data transfer. It is essential for businesses, organizations, and individuals to facilitate collaboration, access information, and use shared services efficiently.
