Correct option is B
A Local Area Network (LAN) is a type of network commonly configured in environments such as computer labs, where multiple computers are interconnected to share resources like printers, files, and internet connections. In a LAN, computers are typically within a small geographical area, such as a building or campus. The printer, in this case, can be accessed by all connected computers.
• LAN allows sharing of printers, files, and internet connections.
• LAN typically supports up to several hundred devices in a localized area.
• The speed of LAN can range from 10 Mbps to several Gbps, depending on the infrastructure.
• LANs often use Ethernet cables or Wi-Fi for connectivity.
• In educational and office environments, LANs enable collaboration and resource sharing.
• (a) PAN: Personal Area Network, designed for a very small area, typically connecting devices like smartphones, laptops, and wearable devices within a few meters.
• (c) MAN: Metropolitan Area Network, spans a larger area than LAN, typically covering a city or large campus, and is used for connecting several LANs within the same geographical region.
• (d) WAN: Wide Area Network, covers a much broader area, connecting multiple LANs and MANs over long distances, often across cities or countries.
