Final answer:
The network that connects computers within a small geographical area, like a building or campus, is a Local Area Network (LAN).
Step-by-step explanation:
A network connecting computers within a small geographical area, such as within a single building or between a group of buildings, is known as a Local Area Network (LAN). LANs are designed to connect computers and other devices within a limited area, enabling them to communicate and share resources such as files, printers, and internet connections efficiently. Unlike Wide Area Networks (WANs), Metropolitan Area Networks (MANs), or Personal Area Networks (PANs), LANs are restricted to a much smaller geographical scope, often confined to a single building or campus.
