What are types of computer network?

Types of computer network

  • LAN- Local Area Network
  • WAN- Wired Area Nework
  • MAN- Metropolitan Area Network
  • WLAN-Wireless local area network
1.LAN-Local Area Network

A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment. Computers and other mobile devices use a LAN connection to share resources such as a printer or network storage
2.WAN-Wired Area Network

A wide area network (WAN) is a network that exists over a large-scale geographical area. A WAN connects different smaller networks, including local area networks (LANs) and metro area networks (MANs). This ensures that computers and users in one location can communicate with computers and users in other locations. WAN implementation can be done either with the help of the public transmission system or a private network.

3.MAN-Metropolitan Area Network
A MAN is ideal for many kinds of network users because it is a medium-size network. MANs are used to build networks with high data connection speeds for cities and towns. 

The working mechanism of a MAN is similar to an Internet Service Provider (ISP), but a MAN is not owned by a single organization. Like a WAN, a MAN provides shared network connections to its users. A MAN mostly works on the data link layer, which is Layer 2 of the Open Systems Interconnection (OSI) model. 

Distributed Queue Dual Bus (DQDB) is the MAN standard specified by the Institute Of Electrical And Electronics Engineers (IEEE) as IEEE 802.6. Using this standard, a MAN extends up to 30-40 km, or 20-25 miles.

4.WLAN-Wireless Local Area Network
A wireless local area network (WLAN) is a wireless distribution method for two or more devices that use high-frequency radio waves and often include an access point to the Internet. A WLAN allows users to move around the coverage area, often a home or small office, while maintaining a network connection.
A WLAN is sometimes call a local area wireless network (LAWN).

Network Address Network Address -  is an identifier for a node or host on a telecommunications  network .  Network addresses  are designed to be unique identifiers across the  network , although some  networks  allow for local, private  addresses  or locally administered  addresses  that may not be unique. Table A.2. Example Network; Host Addressing hostname interface IP address wan-gw wan0 205.254.209.73/30 isdn-router ( Ethernet ) 192.168.99.1/24 branch-router ( Ethernet ) 192.168.98.254/24 service-router ( Ethernet ) 192.168.100.1/24 8 more rows IP VERSION 1. IPv4 - IP version 4 -is the standard verion 2. IPv6 - IP version 6 - is the advanced version IPv4 addresses are cononically represented in dotted-decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 172.16.254.1. Each part reprsents a group of 8 bits(octet) of of the address IP Configuration 1. Start Button 2. Click Run 3. Typ
