Which type of wired network is commonly used to share a printer among 8 computers in an office room?

Correct option is A

A LAN (Local Area Network) is the most commonly used type of wired network for sharing resources such as a printer among multiple computers within a single office room. LANs are designed to cover a small geographic area like a room, building, or campus and provide high-speed, reliable connectivity. Because all 8 computers are located in the same office environment, a LAN is the most efficient and appropriate networking solution.
Important Key Points:
1. Definition of LAN: A Local Area Network connects computers and devices within a limited physical area, such as a room or office.
2. Typical Uses: Sharing printers, files, internet connections, and other resources among nearby computers.
3. Why LAN Fits the Scenario? The computers are in the same office room, requiring short-distance, high-speed communication.
4. Wired LAN Technologies: Commonly use Ethernet cables (UTP/STP) and network switches.
5. Advantages of LAN:
· High data transfer speed
· Low error rate
· Easy resource sharing
6. Real-World Examples: School computer labs, office networks, and home networks.
Knowledge Booster:
· Why option (b) MAN is incorrect? A Metropolitan Area Network covers a city-wide area, which is unnecessary for a single office room.
· Why option (c) PAN is incorrect? A Personal Area Network connects personal devices over a very short range (e.g., Bluetooth), not ideal for office printer sharing.
· Why option (d) WAN is incorrect? A Wide Area Network spans large geographic distances, such as countries or continents, making it unsuitable for this use case.
