Q2: What are the types of computer network?

A2:

  • LAN(Local Area Network)
  • PAN(Personal Area Network)
  • MAN(Metropolitan Area Network)
  • WAN(Wide Area Network)

Q3: What is a LAN?

A3: Full form of LAN is Local Area Network, LAN is a group of computers connected to each other in a small area such as office, building. It is used to connect two or more personal computers through a communication medium such as  coaxial cable, twisted pair, etc. LAN is not very costly as it is built with inexpensive hardware such as  network adapters, hubs and ethernet cables. The data in Local Area Network will be transferred at an extremely faster rate. LAN provides higher security.

Q4: What is PAN?

A4: Full form of PAN is Personal Area Network. It is a network arranged within a range of 10 meters, typically within an individual person. PAN is used for connecting the computer devices of personal use. Personal Area Network idea was bought by Thomas Zimmerman who was a research scientist. It covers an area of 30 feet. Personal computer devices that are used to develop the personal area network are the mobile phones, laptop,  play stations and media players.
