Types of Computer Network?


 

    PAN

                           A personal area network (PAN) is a computer network for interconnecting devices centered on an individual person's workspace. A PAN provides data transmission amongst devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet (an uplink) where one master device takes up the role as gateway. A PAN may be carried over wired computer buses such as USB.
wireless personal area network (WPAN) is a low-powered PAN carried over a short-distance wireless network technology such as IrDAWireless USBBluetooth and ZigBee. The reach of a WPAN varies from a few centimeters to a few meter




     WAN

  A wide area network (WAN) is a telecommunications network or computer network that extends over   a large geographical distance/place. Wide area networks are often established with leased   telecommunication circuits.Business, education and government entities use wide area networks to       relay data to staff, students, clients, buyers, and suppliers from various locations across the world. In     essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet may be considered a WAN.



    LAN

     Stands for "Local Area Network" and is pronounced "lan." A LAN is a network of connected devices that exist within a specific location. LANs may be found in homes, offices, educational institution, or other areas.   
  local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LANis confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.A LAN may be wiredwireless, or a combination of the two. A standard wired LAN uses Ethernet to connect devices together. Wireless LANs are typically created using a Wi-Fi  signal. If a router supports both Ethernet and Wi-Fi connections, it can be used to create a LAN with both wired and wireless devices.


    MAN

metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term MAN is applied to the interconnection of networks in a city into a single larger network which may then also offer efficient connection to a wide area network.It is also used to mean the interconnection of several local area networks in a metropolitan area through the use of point-to-point connections between them
