Which of the following term is used for a computer network that typically connects personal computers within a limited geographical area, usually within a single building ?

Question

Accepted Answer

The correct option is (1):
The correct term for a computer network connecting devices within a small, limited geographical area, such as a home, office, or a single building, is a **Local Area Network (LAN)**. The fundamental purpose of a LAN is to provide high-speed connectivity and resource sharing—like printers, files, and an internet connection—among personal computers and other devices within this confined physical space. LANs are typically characterized by their high data transfer rates, low latency (minimal delay), and private ownership, as they are managed by the organization or individual occupying the building. The network's close physical proximity is the defining characteristic that makes LAN the precise answer to this question.

The incorrect options are (2), (3), and (4):
The remaining options describe networks with a much broader or a much more specialized scope. **WAN (Wide Area Network)**, of which the internet is the largest example, connects multiple individual LANs across massive geographical distances, such as cities, countries, or even continents. **MAN (Metropolitan Area Network)** is an intermediate network, connecting networks across an entire city or a large campus area, which is significantly larger than the limited single-building area defined for a LAN. **BAN (Body Area Network)**, conversely, refers to a specialized, extremely short-range network used to interconnect small, mobile, computing devices worn on or implanted in the body, such as medical sensors or fitness trackers. None of these other network types align with the description of connecting personal computers solely within a limited geographical area like a single building.
