Difference between LAN, MAN, WAN and PAN

Computer:

   Computer is an electronic device that takes input from the user in the form of data and it processes the data according o the given instructions and displays required output.

Network:

• A system of roads, railway lines, nerves, etc. that are connected to each other.
•  A group of people or companies that work closely together.

Computer Network:

•  A computer network is a set of connected computers. 
•  Computers on a network are called nodes. 
•  A network consists of two or more computers that are linked in order to share resources.

Examples :

• Printers
• Scanners
• CDs

Types of Network:

• A computer network can be categorized by their size. 
• A computer network is mainly of four types:

1. LAN(Local Area Network)
2. PAN(Personal Area Network)
3. MAN(Metropolitan Area Network)
4. WAN(Wide Area Network)

( Types of Networks )

Difference between LAN, MAN, WAN and PAN:

( Difference between LAN, MAN, WAN and PAN)

Local Area Network:

• Local Area Network is a group of computers connected to each other in a small area such as building, office.
• LAN is used for connecting two or more personal computers through a communication medium such as twisted pair, coaxial cable, etc.
• It is less costly as it is built with inexpensive hardware such as hubs, network adapters, and Ethernet cables.
• The data is transferred at an extremely faster rate in Local Area Network.
• Local Area Network provides higher security.

Metropolitan Area Network:

• MAN(Metropolitan Area Network)
• A metropolitan area network is a network that covers a larger geographic area by interconnecting a different LAN to form a larger network.
• Government agencies use MAN to connect to the citizens and private industries.
• In MAN, various LANs are connected to each other through a telephone exchange line.
• It has a higher range than Local Area Network(LAN).

Wide Area Network:

• WAN(Wide Area Network)
• A Wide Area Network is a network that extends over a large geographical area such as states or countries.
• A Wide Area Network is quite bigger network than the LAN.
• A Wide Area Network is not limited to a single location, but it spans over a large geographical area through a telephone line, fiber optic cable or satellite links.
• The internet is one of the biggest WAN in the world.
• A Wide Area Network is widely used in the field of Business, government, and education.

Personal Area Network:

• PAN(Personal Area Network)
• Personal Area Network is a network arranged within an individual person, typically within a range of 10 meters.
• Personal Area Network is used for connecting the computer devices of personal use is known as Personal Area Network.
• Personal Area Network covers an area of 30 feet.
• Personal computer devices that are used to develop the personal area network are the laptop, mobile phones, media player and play stations.
