Explanation:

A computer network is a collection of interconnected devices, such as computers, printers, servers, and routers, that are linked together to facilitate communication and data sharing. There are different types of computer networks, each designed for specific purposes and geographical areas.

Local Area Network (LAN):
A Local Area Network (LAN) is a type of computer network that covers a small area, such as a home, office building, or school. It connects devices within a limited geographical area and is typically owned and managed by a single organization. LANs are used for sharing resources, such as files, printers, and internet access, among connected devices.

Personal Area Network (PAN):
A Personal Area Network (PAN) is the smallest type of computer network, typically used for connecting personal devices, such as smartphones, tablets, and wearable devices. PANs are designed for personal use and enable communication between devices in close proximity to each other, usually within a range of a few meters.

Remote Area Network (RAN):
There is no such type of computer network known as Remote Area Network (RAN). This option is incorrect and does not exist in the context of computer networks.

Metropolitan Area Network (MAN):
A Metropolitan Area Network (MAN) is a type of computer network that spans a larger geographical area than a LAN but smaller than a wide area network (WAN). MANs are usually owned and operated by multiple organizations and are used to connect multiple LANs within a city or metropolitan area. They provide high-speed connectivity and enable sharing of resources and services between connected networks.

Therefore, the correct answer is option 'C' - Remote Area Network (RAN), as it is not a recognized type of computer network.
