What is a computer network?

A computer network is a system that connects multiple computers and devices so they can communicate and share resources. These networks can be wired, using Ethernet cables, or wireless, using Wi-Fi radio signals.

Computer networks allow users to share files, printers, applications, and internet connections within a business or home environment. Whether you’re transferring documents, streaming media, or accessing shared databases, a network is the backbone that enables devices to work together efficiently.

There are several types of computer networks, including Local Area Networks (LANs) for small office environments, and Wide Area Networks (WANs) for larger geographic connections. In modern business environments, networks also support remote access, cloud integration, and cybersecurity controls.
