LAN is easy to design and maintain.Ī Communication medium used for LAN has twisted pair cables and coaxial cables. One can use it for an office building, home, hospital, schools, etc. LAN’s cover a smaller geographical area and are privately owned. Data transmits at a very fast rate as the number of computers linked are limited. LAN or Local Area Network links network devices in such a way that personal computer and workstations can share data, tools and programs. Multiple computers can simultaneously interact.Ī huge group of computers communicate at the same time. It spans large locality and connects countries together. It covers relatively large region such as cities, towns. Content: LAN Vs MAN Vs WANĪ network that connects a group of computers in a small geographical area. As against, this could not be possible in case of MAN and WAN which are obliged to use public, private, leased communication hardware as these networks are spanned across a magnificent area. LAN covers the smallest area MAN covers an area larger than LAN and WAN comprises the largest of all.įurthermore, LAN networks rely on the hardware and communication devices owned by them for the transmission. In MAN additional cables are required to connect two LAN which is another problem.One of the significant differences is in the geographical area they cover, i.e. The technical people are network administrators and troubleshooters. To setup MAN it requires technical people that can correctly setup MAN. Data can be secured but it needs high trained staff and security tools.

In MAN there are high chances of attacking hackers on the network compared to LAN. So it required the high cost to set up fiber optics for the first time. If MAN is installed on copper wires then there will be very low speed. MAN cannot work on traditional phone copper wires. This is due to a security problem and other extra configuration. If MAN becomes bigger then it becomes difficult to manage it. Disadvantages of metropolitan area network (MAN) This is due to the fast configuration of links. MAN is a faster way to connect two fast LANs together. So multiple users can get the same high-speed internet. In some installation of MANs, users can share their internet connection. Files and databases can be transferred fast. MAN uses fiber optics so the speed of data can easily reach upon 1000 Mbps. On MAN you can send local emails fast and free. In MAN data is easily managed in a centralized way. It is less expensive to attach MAN with WAN. The speed of metropolitan area network is about 1000 Mbps. MAN also uses routers and switches to transfer data. The main purpose of MAN is to interconnect two LAN together. SMDS is a connectionless service meaning data info is stored in the header and then it is transferred through any network. In SMDS, data is transferred in packets over the large geographical area. ATM used packet switching and circuit switching to transfer real-time data. This method is best for doing audio and video conference online. In ATM data is distributed online in the form of small fixed size packets. Mostly ATM is a widely used method in MAN. As FDDI can handle thousands of users so this standard is also included in MAN.ĪTM (Asynchronous transfer mode) was developed in 1980 to transfer digital data fast.

SMDS (Switched multi-megabit data service)įDDI is used for transferring data in LAN.FDDI (Fiber distribution data interface).Some of these technologies are mentioned below:. MAN depends upon different technologies to establish a network. MAN usually involves connection of fiber optics wires to boost data transfer speed. MAN is made with a combination of several LAN through point to point connections. MAN connect users within an area larger than local area network (LAN) but smaller than a wide area network (WAN). What is a metropolitan area network (MAN)Ī metropolitan area network (MAN) is a network which covers a city or a large university campus.
