WAN (Wide Area Network)

A Wide Area Network (WAN) is a type of computer network that covers a large geographic area, such as a city, country, or even globally. It connects multiple Local Area Networks (LANs), enabling communication and data sharing between distant locations. WANs often use technologies like satellite links, fibre-optic cables, and telephone lines. The Internet is the largest example of a WAN, allowing people to access information and connect with others worldwide. WANs are essential for businesses with multiple offices and for services that require long-distance networking.
