Local Area Network (LAN)
Wide Area Network (WAN)
Wireless Local Area Network (WLAN)
Campus Area Network (CAN)
Metropolitan Area Network (MAN)
Storage Area Network (SAN)
System-Area Network (SAN)
Personal Area Network (PAN)
This is a network that is created in a very short distance, its maximum capacity is from 10 meters to 12 meters, in this type of network two people can easily transfer data among themselves, the best example of this is Bluetooth, and all are connected to CPU devices like keyboard, mouse, printer, etc.
Local Area Network (LAN)
A network that connects two or more computers in the same place is called a local area network, the use of this type of network is limited to a small area, this network is used on a small scale in small offices or colleges. The capacity of this network is up to 5 km. The data transfer rate in this type of network ranges from about 10 Mbps to 100 Mbps.
Wide Area Network (WAN)
This type of network is used to cover the area of the whole world, in which point-to-point link is used in the world wide area network, in which many systems can be connected together.
