Comparison
LAN:
o LAN is the short form, Local area network.
o If two or more computers and peripheral devices are connected within a small area such as a room, office, or campus, it is called LAN. That is the group of computers on a LAN that share a common connection.
o The LAN data transmission speed is 10-100mbps and it is slow compared to WAN.
oh Bus Y Ring The topologies are used in the LAN network.
o Some data errors occur in the LAN protocol.
o In the office or home network, they usually connect by Ethernet cable and have high speed connection. and it is wireless configuration is then called Wifi.
o In LAN, computer terminals are physically connected with wires.
o The LAN connection sharing range is 1km.
o Also, the cost of LAN is lower compared to WAN & MAN.
PALE:
o WAN is short for wide area network.
o It is the largest network and can interconnect networks around the world and is not restricted to a geographic location.
o The example of WAN is the connection of several branches of multinational such as Microsoft and these branches are linked through the use of a microwave satellite communication system.
o In addition, the main example of a WAN system is telecommunications system.
o The WAN data transmission speed is 256Kbps to 2Mbps and it has higher speed compared to LAN & MAN.
oh ATM, Frame Relay, Sonnet topology are used in the WAN network.
o Most WANs exist to connect LANs that are not in the same geographic area.
o WAN connection sharing range is up to 10,000km.
o Also, the cost of WAN is very high compared to LAN & MAN.
MEN:
o MAN is short for metropolitan area network.
o It is larger than the LAN network system and connects computer users in a particular geographical area.
o The main example of a MAN network is Cable TV.
o In addition, a large university may have such a large network that it can be classified as MAN. And the MAN network system generally exists to provide connectivity to large corporations.
o The data transmission speed of MAN is 5-10Mbps and it is slower than WAN and has higher speed than LAN.
oh Distributed Queue Dual Bus [DQDB] topology is used in the MAN network.
o The MAN network system is larger than a LAN and smaller than a WAN.
o MAN connection sharing range is up to 50km.
o In addition, the cost of MAN is higher than that of LAN.
