Metropolitan Area Network (MAN)

 

It was developed in 1980s.It is basically a bigger version of LAN. It is also called MAN and uses the similar technology as LAN. It is designed to extend over the entire city. It can be means to connecting a number of LANs into a larger network or it can be a single cable. It is mainly hold and operated by single private company or a public company.



Characteristics of MAN

  • It generally covers towns and cities (50 km)
  • Communication medium used for MAN are optical fibers, cables etc.
  • Data rates adequate for distributed computing applications.

Advantages of MAN

  • Extremely efficient and provide fast communication via high-speed carriers, such as fibre optic cables.
  • It provides a good back bone for large network and provides greater access to WANs.
  • The dual bus used in MAN helps the transmission of data in both directions simultaneously.
  • A MAN usually encompasses several blocks of a city or an entire city.

Disadvantages of MAN

  • More cable required for a MAN connection from one place to another.
  • It is difficult to make the system secure from hackers and industrial espionage(spying) graphical regions.

Local Area Network (LAN)

  LANs are used widely as it is easy to design and to troubleshoot. Personal computers and workstations are connected to each other through LANs. We can use different types of topologies through LAN, these are Star, Ring, Bus, Tree etc. LAN can be a simple network like connecting two computers, to share files and network among each other while it can also be as complex as interconnecting an entire building. LAN networks are also widely used to share resources like printers, shared hard-drive etc. Characteristics of LAN LAN's are private networks, not subject to tariffs or other regulatory controls. LAN's operate at relatively high speed when compared to the typical WAN. There are different types of Media Access Control methods in a LAN, the prominent ones are Ethernet, Token ring. It connects computers in a single building, block or campus, i.e. they work in a restricted geographical area. Applications of LAN One of the computer in a network can become a server serving all the ...

Wireless Network

  Digital wireless communication is not a new idea. Earlier,  Morse code   was used to implement wireless networks. Modern digital wireless systems have better performance, but the basic idea is the same. Wireless Networks can be divided into three main categories: System interconnection Wireless LANs Wireless WANs System Interconnection System interconnection is all about interconnecting the components of a computer using  short-range radio . Some companies got together to design a short-range wireless network called  Bluetooth  to connect various components such as monitor, keyboard, mouse and printer, to the main unit, without wires. Bluetooth also allows digital cameras, headsets, scanners and other devices to connect to a computer by merely being brought within range. In simplest form, system interconnection networks use the master-slave concept. The system unit is normally the  master , talking to the mouse, keyboard, etc. as  slaves . Wirel...
