What is computer network?

A computer network is a collection of interconnected computers that can communicate and share resources with each other.

This interconnection can be achieved through various means, such as wired (e.g., Ethernet cables) or wireless (e.g., Wi-Fi) technologies. Computer networks enable the sharing of information, files, and resources like printers and internet connections.

They can range from small local area networks (LANs) within a single building to vast global networks like the internet, connecting computers worldwide. Networks use protocols and standards to facilitate communication and ensure compatibility between different devices and systems.
