3. NETWORK & ITS TYPES
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]

4. LAN [ local area 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.

5. WLAN[wireless local area network]
 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.

6. 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

 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.
