Answer:
(a) Metropolitan Area Network
Explanation:
The PAN (Personal Area Network), LAN (Local Area Network), MAN (Metropolitan Area Network) and WAN(Wide Area Network), among others, are types of computer area networks.
In the LAN, networking devices are all located in a small geographical area (a few kilometers). This can be used in schools, offices and hospitals. LANs are usually owned by individuals. Networking devices in a LAN are usually connected via twisted pair and/or coaxial cables. They are very easy to set up. Data transmission is very fast in a LAN.
In the MAN, networking devices are all located in a geographical area usually bigger than the one in LAN. The area can span a campus or even a city. MANs are a bit difficult to set up compared to LANs and may not be owned by individuals. Data transmission is also fast in a MAN but not as fast as that of LAN.
In the WAN, networking devices are all located in a large geographical area usually across cities of a country. WANs are very difficult to set up compared to LANs and MANs. A WAN could be a combination of one or more LANs or MANs. Data transmission in slow in WANs.
In the PAN, a device is able to communicate to another device that is usually close to it. It could be wired(via USB) or wireless (via bluetooth). Devices in a PAN are usually very close to one another (only a few meters apart).
