METROPOLITAN AREA NETWORK(MAN). □ It is in between LAN & WAN technology that covers the entire city. □ It uses similar technology as LAN. □ It can be. by a network, it is classified as: – Local Area Network (LAN). – Metropolitan Area Network (MAN). – Wide Area Network (WAN). – Personal Area Network (PAN). Wide-area networks (WANs): A system of LANs connected in this way is called a wide-area network (WAN). Most LANs Metropolitan Area Network - MAN.
Devices used for transmission of data through MAN are: Some of the different networks based on their main purpose are:.

This can include things like a watch, special glasses, tracking devices and heart-rate monitors. For example, an Alzheimer's patient could be outfitted with a location tracking device and a cellular communication device. If they leave a certain area, family members can be alerted with a text or e-mail message to the location of their loved one. Computer networks can be characterized in the term of the geographic area they occupy and the purpose of the network within this geographic area.
A personal area network is a computer network organized around an individual person within a single building. A local area network consists of a computer network at a single site for sharing resources, typically an individual office building. A metropolitan area network consists of a computer network across an entire city, college campus or small region.
A wide area network occupies a very large area, such as an entire country or the entire world. Special purpose networks include storage area networks, home area networks and body area networks. To unlock this lesson you must be a Study.

There are so many different types of computer networks in existence, it can be hard to understand the differences between them, particularly the ones with very similar-sounding names.
Types of Networks There are several different types of computer networks. Some of the different networks based on size are: Some of the different networks based on their main purpose are: Personal Area Network A personal area network , or PAN , is a computer network organized around an individual person within a single building. This type of network provides great flexibility. For example, it allows you to: Send a document to the printer in the office upstairs while you are sitting on the couch with your laptop.
Upload a photo from your cell phone to your desktop computer. Watch movies from an online streaming service to your TV.
Local Area Network A local area network , or LAN , consists of a computer network at a single site, typically an individual office building. Metropolitan Area Network A metropolitan area network , or MAN , consists of a computer network across an entire city, college campus or small region.
Wide Area Network A wide area network , or WAN , occupies a very large area, such as an entire country or the entire world. Private Networks One of the benefits of networks like PAN and LAN is that they can be kept entirely private by restricting some communications to the connections within the network.

Computer Hardware. Data transmits at a very fast rate as the number of computers linked are limited.
By definition, the connections must be high speed and relatively inexpensive hardware Such as hubs, network adapters and Ethernet cables. LANs cover smaller geographical area Size is limited to a few kilometers and are privately owned. One can use it for an office building, home, hospital, schools, etc.
LAN is easy to design and maintain. A Communication medium used for LAN has twisted pair cables and coaxial cables.
It covers a short distance, and so the error and noise are minimized. Today, speeds are normally or Mbps.
Propagation delay is very short in a LAN. A LAN typically relies mostly on wired connections for increased speed and security, but wireless connections can also be part of a LAN. The fault tolerance of a LAN is more and there is less congestion in this network. For example: A bunch of students playing Counter Strike in the same room without internet. It connects two or more computers that are apart but resides in the same or different cities. MAN is designed for customers who need a high-speed connectivity.
Speeds of MAN ranges in terms of Mbps. The fault tolerance of a MAN is less and also there is more congestion in the network. It is costly and may or may not be owned by a single organization. The data transfer rate and the propagation delay of MAN is moderate.
Devices used for transmission of data through MAN are: Examples of a MAN are the part of the telephone company network that can provide a high-speed DSL line to the customer or the cable TV network in a city.
The technology is high speed and relatively expensive.
