Differences between LAN and WAN

The differences between LAN and WAN is as follows:

LAN (Local Area Network)
1.	LAN is used to connect computers at one place, in one room or a building.
2.	LAN covers small and limited area.
3.	Data transfer speed is very fast in LAN because of small distance.
4.	Local Area network speed is normally form 1 to l00 Mbps.
5.	LAN is less costly.
6.	LAN is usually connected through wires.
7.	Normally, the   connection    in    a    LAN    is permanent using wires.
8.	LAN is used for sharing data, information, files and hardware like printers, hard disk, modem etc.
9.	LAN has   less   possibility   of data transmission error.
10.	LAN is used to transfer data over small distances.
11	LAN is easy to install and configure.
12	LAN is easy to troubleshoot.
WAN (Wide Area Network)
1	WAN is used to connect computers anywhere in the world.
2	WAN can cover larger area. It can cover cities, countries and even continents.
3	Data transfer speed is slower in WAN.
4	Transmission     speeds     are     normally 56 kbps to 45 Mbps.
5	The hardware needed for a WAN is more expensive.
6	WAN is usually connected through telephone lines, fiber optic cable or through wireless media.
7	The    connection    in    WAN    may not be permanent.
8	WAN is used to share only data and information like Email and file transfer
9	WAN has more possibility of data transmission error because of long distance.
10	WAN is used to transfer data over long distances.
11	WAN is difficult to install and configure due to connecting computers at multiple and distant sites.
12	WANs are difficult to troubleshoot.
