Explanation:
A campus area network (CAN) is a computer network that interconnects local area networks throughout a limited geographical area, such as a university campus, a corporate campus, or a military base. It could be considered a metropolitan area network that is specific to a campus setting.
A campus area network is, therefore, larger than a local area network but smaller than a wide area network. The term is sometimes used to refer to university campuses, while the term corporate area network is used to refer to corporate campuses instead. Although not considered a wide area network, a CAN extends the reach of each local area network within the campus area of an organization. In a CAN, the buildings of a university or corporate campus are interconnected using the same types of hardware and networking technologies that one would use in a LAN. In addition, all of the components, including switches, routers, and cabling, as well as wireless connection points, are owned and maintained by the organization.
Answer option C is incorrect. Local Area Network (LAN) represents a network that covers a very close geographic area, such as a floor of a building, a building itself, or a campus environment. LAN is a high-speed network that connects computers, printers, and other network devices together. The media types used in LANs include Ethernet, Fast Ethernet (FE), Gigabit Ethernet (GE), Token Ring, and FDDI.
A LAN may include servers, workstations, hubs, bridges, switches, routers, gateways, firewalls, etc.
Answer option A is incorrect.
A Metropolitan Area Network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large Local Area Network (LAN) but smaller than the area covered by a Wide Area Network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.
A MAN usually interconnects a number of local area networks (LANs) using a high- capacity backbone technology, such as fiber-optical links, and provides up-link services to wide area networks and the Internet. Examples of metropolitan area networks of various sizes can be found in the metropolitan areas of London, England; Lodz, Poland; and Geneva, Switzerland. Large universities also sometimes use the term to describe their networks.
A recent trend is the installation of wireless MANs.
Answer option B is incorrect.
A wide area network (WAN) is a geographically dispersed telecommunications network. The term distinguishes a broader telecommunication structure from a local area network (LAN).
A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks. An intermediate form of network in terms of geography is a metropolitan area network (MAN).
A wide area network is also defined as a network of networks, as it interconnects LANs over a wide geographical area.
