  NETWORK & ITSTYPES Networking is the process by which two or more computers are linked together for a flawless communication. There are about eight types of network, which are :-  LAN [LOCAL AREA NETWORK]  WLAN[WIRELESS LOCAL AREA NETWORK]  WAN[WIDE AREA NETWORK]  MAN[METROPOLITAN AREA NETWORK]  SAN[STORAGE/SYSTEM AREA NETWORK]  CAN[CAMPUS/CLUSTER AREA NETWORK]  PAN[PERSONAL AREA NETWORK]  DAN[DESK AREA NETWORK]

  LAN [ localarea network ]  Connects networking devices with in short area, e.g. small offices, home, internet cafes etc.  Uses TCP/IP network protocol for communication between computers.  Can be control and administrated by single person or organization. WAN [ wide area network ]  WAN cover large distance for communication between computers.  Internet is the best example of WAN, which covers the entire earth.  Uses network protocols like ATM, X.25, and Frame Relay for long distance connectivity.

  WLAN[wireless local areanetwork]  A LAN based on wireless network technology, mostly referred as Wi-Fi.  No wires are used, but radio signals are the medium for communication.  Wireless network cards are required to be installed in the systems for accessing any wireless network around. MAN[metropolitan area network]  Is not mostly used, but has its importance for some government bodies and organizations on larger scale.  It falls in between LAN and WAN.  Covers large span of physical area than LAN but smaller than WAN, such as a city.

  SAN[storage area network] Pan[personal area network]  Used for data storage and it has no  Used for communication among use for most of the organization but computer devices. data oriented organizations.  Can be used for communication  Connects servers to data storage among the personal devices or for devices by using Fiber channel connecting to a higher level network technology. and internet. CAN[campus area network] DAN [desk area network]  A networking, spanning with multiple  A multimedia workstation based LANs but smaller than MAN. around ATM interconnect.  Mostly used in relatively large  All communication between universities or local business offices peripherals and even between CPU and buildings. and its main memory is achieved by sending ATM cells through a switch fabric.
