Definition of MAN (Metropolitan Area Network)

Definition of MAN (Metropolitan Area Network) is a computer network that is large and spacious which is typically used in areas such as schools, colleges, malls and even can also cities. Actually there are two types of connections that are usually used the first is by using a wireless connection and the second using fiber optic cable. For instance, a school or campus MAN has a connection consisting of multiple LAN and located in a radius of several kilos of such areas. Then the campus with the MAN connections also have links with other universities to form a WAN or the Internet.

There are also other examples with some of the technology used MAN connections like ATM, FDDI and SMDS. Here below I give an explanation also about ATM, FDDI and SMDS.

• ATM or Asynchronous Transfer Mode instead of Automated Teller Machine yaa. ATM is a cell relay network protocol that clicking encode traffic or traffic data to a smaller cell forms such as 53 bytes, 48 bytes and 5 bytes.
• FDDI or Fiber Distributed Data Interface is a standard data transmission in a LAN that includes a hefty range is up to 200 kilometers away. FDDI can also include thousands of users. Standard medium is used to connect fiber optic, even though it could also use copper wires, but the conditions must be in accordance with the FDDI technology if it does not then the transmission will be interrupted.
• SMDS or Switched Multi-megabit Data Services is a service connection to the LAN, MAN and WAN with the exchange of data based on standard IEEE 802.6 DQDB. For the connection between MAN and LAN can be done using radio signals, microwaves and infrared.

Thus the notion and function of the Metropolitan Area Network , may be useful for you.
