Propagation delay is one of the biggest problems faced here. Currently, 10BaseT Ethernets are the most common. LAN, acronym for local area network, is a limited area network that interconnects computer systems and their associated devices within a distinct geographical area such as a building, office, university campus or a commercial establishment.

WANs typically span a large geographical area which is virtually limitless, usually in kilometers and the range can be extended using repeaters. You might not think of your wireless headset, your printer or your smartphones as components in a network, but they are definitely talking with each other. The technology is high-speed, and is relatively expensive. Universal components consist of the physical medium that connects devices, interfaces on the individual devices that connect to the medium, protocols that transmit data across the network, and software that negotiates, interprets and administers the network and its services. Local area network is usually a building or a campus with a very limited distance coverage of up to a few hundred meters, metropolitan area network is relatively a new class of network which extends beyond the area of a LAN but smaller than that of a WAN. It uses the Internet to allow people to log into a network remotely and access its resources, but encrypts the connection to thwart eavesdroppers. The data transfer rate of MAN is moderate. Ethernet supports networks built with twisted-pair 10BaseT , thin and thick coaxial 10Base2 and 10Base5, respectively , and fiber-optic 10BaseF cabling. Data transmits at a very fast rate as the number of computers linked are limited.
One of the major differences is of course the geographical area. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs perhaps one per roomand occasionally a LAN will span a group of nearby buildings.
MAN is designed for customers who need a high-speed connectivity. Laying fiber may make sense when connecting a campus but becomes more expensive when connecting greater distances. MANs connect multiple LANs in a common geographical area which can be in the range of up to kilometers or sometimes more.
A LAN Local Area Network is a group of computers and the network devices connected together usually within the same building. A metropolitan area network, or MAN, is a much larger network that connect network of computers spanning a geographical area larger than a LAN but smaller than the area covered by a WAN.
To save money, an organization may opt for wireless technology or lease lines from a third party. One can use it for an office building, home, hospital, schools, etc. Components of LAN, WAN, and MAN Apart from computers, there are essentially some basic components required to establish a local area network such as network adapter cards, network cables, hubs, repeaters, switches, bridges, routers, network server, and LAN software.

Bandwidth and latency are the two main factors governing the performance of a network. By definition, the connections must be high-speed and relatively inexpensive e. The name is exactly what it sounds like: a network that covers an area wider than a LAN. Following are some Ethernet features: Ethernet transmits data at up to ten million bits per second 10 Mbps. One of the major differences is of course the geographical area. In networking, what is bandwidth and latency? Unlike LAN, WAN uses switching that allows multiple computers to connect with several switches instead of connecting with each other. The most popular WAN is the one you're using to read this article: the Internet. Twisted pair cables plug into switches using RJ connectors, similar to phone jacks. Wide Area Network may or may not be privately owned. WAN vs. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs perhaps one per room , and occasionally a LAN will span a group of nearby buildings.
It is asynchronous in the sense that although cells are relayed synchronously, particular users need not send data at regular intervals. Speeds of MAN ranges in terms of Mbps.
