2. They are Four of Networks:
1.LAN (local area network)
2.PAN (personal area network)
3.MAN (metropolitan area network)
4.WAN (wide area network)
3. LAN (local area network)
A local area network is a computer network that interconnects
computers within a limited area such as a residence, school,
laboratory, university campus or office building.
4. PAN (personal area network)
A personal area network (PAN) connects electronic devices within a
user's immediate area. The size of a PAN ranges from a few
centimeters to a few meters. One of the most common real-world
examples of a PAN is the connection between a Bluetooth earpiece
and a smartphone. PANs can also connect laptops, tablets, printers,
keyboards, and other computerized devices.
5. MAN (metropolitan area network)
A metropolitan area network (MAN) is a computer
network that connects computers within a metropolitan
area, which could be a single large city, multiple cities
and towns, or any given large area with multiple
buildings.
6. WAN (wide area network)
A wide area network (WAN) is a large
computer Network that connects groups of computers
over large distances. WANs are often used by large
businesses to connect their office networks; each
office typically has its own local area network,
or LAN, and these LANs connect via a WAN.
