LAN:
o LAN is an abbreviation, The local network ,
o If two or more computers and peripheral devices are connected in a small area, such as a room, office, or campus, LAN This is a group of computers on a local network with a common connection.
o Local network data transfer rate 10-100 Mbps and it is slow compared to the WAN.
about bus and Ring topologies are used in the local network.
o There are several data errors in the LAN protocol.
o In the office or on the home network, they are usually connected Ethernet cables and have high speed connection. And if it is wireless settings then it's called WLAN ,
o In a LAN, computer terminals are physically connected to wires ,
o LAN Connection Range 1 km ,
o In addition, the cost of LAN is lower compared to WAN & MAN.
WAN:
o WAN is an abbreviation for Global network ,
o It is the largest network and can connect networks around the world and is not limited by geographic location.
A WAN example is a mix of different branches. MNC such as Microsoft, and these branches are associated with the use of a microwave satellite communications system.
o In addition, a prime example of a WAN system is Telecommunication system ,
o WAN data transfer rate 256 Kbps to 2 Mbps and it has a higher speed compared to LAN and MAN.
about ATM, Frame Relay, Sonnet topology used in the WAN.
o Most WANs exist for connecting local networks that are not in the same geographic area.
o WAN access range to 10,000 km ,
o In addition, the cost of a WAN is very expensive compared to LAN and MAN.
HUMAN:
o MAN is an abbreviation for Metropolitan area ,
o It is larger than a networked network system, and it connects computer users in a specific geographic area.
o The main example of a MAN network is Cable TV ,
o In addition, a large university can have such a large network that it can be classified as MAN. And the MAN network system usually exists to provide connectivity to large corporations.
o MAN transfer rate 5-10Mbps and it is slower than the WAN, and has a higher speed than the LAN.
about Dual Bus Distributed Queue [DQDB] topology is used in the MAN network.
The MAN network system is larger than the local area network and smaller than the WAN.
o MAN sharing range - up to 50 km ,
o In addition, MAN costs more than LAN.
