Understanding Metropolitan Area Network

Understanding Metropolitan Area Network 
Understanding Metropolitan Area Network (MAN), Functions, Strengths, Weaknesses and Examples: is a computer network that usually covers a large city or campus.

Understanding Metropolitan Area Network (MAN)
Metropolitan Area Network (MAN) is a network that is wider than the Local Area Network (LAN). The area used in the MAN network is in a country. In this case, a computer network connects several Local Area Network (LAN) networks into a larger area environment. Multiple Local Area Netwrok (LAN) into one network can also be called Metropolitan Area Network (MAN).
Metropolitan Area Network (MAN) can be found on one campus or in a rather large area (can also be a city). Metropolitan Area Networks (MAN) are usually not owned by only one organization. Just like a Local Area Network (LAN), the Metropolitan Area Network (MAN) also has wireless with relatively similar advantages and disadvantages. Metropolitan Area Network (MAN) is also able to support text and voice data, and can even be connected to cable television networks or radio waves.
A metropolitan area network (MAN) is a computer network that usually covers a large city or campus. MAN usually interconnects a number of local area networks (LANs) using high capacity backbone technology, such as fiber-optic links, and provides up-link services for wide area networks (or WANs) and the Internet. The scope of this MAN is between 10 to 50 km, this MAN is the right network to build a network between offices in one city between factories / agencies and head office within its reach.
Metropolitan Area Network (MAN) is a computer network in a city with high-speed data transfer, which connects various locations such as campuses, offices, government, and so forth. MAN network is a combination of several LANs. Metropolitan Area Network (MAN) is basically a LAN version that is larger and usually uses the same technology as a LAN. MAN is an option for building computer networks between offices in a city.
MAN is usually able to support data and voice, and can even be connected with cable television networks. MAN only has one or two cables and does not have a switching element, which functions to manage packets through several cable outputs. The existence of switching elements makes the design simpler.

The standard describes MAN as:
"MAN is optimized for larger geographic areas of the LAN, starting from several building blocks for the entire city. MAN can also depend on moderate-to-high-speed data communication channels. MAN may be owned and operated by a single organization, but will usually be used by many individuals and organizations. MAN may also be owned and operated as a public utility. They will often provide facilities for internetworking local networks. "
Authors Kenneth C. Laudon and Jane P. Laudon (2001) Management Information Systems: Managing the Digital Firm 10th ed. defines a metropolitan area network as:
"A Metropolitan Area Network (MAN) is a large computer network that covers a metropolitan area or campus. Geographical coverage that falls between WAN and LAN. MAN provides Internet connectivity for LANs in metropolitan areas, and connects them to wider area networks such as the Internet. "
