Types of Network : How Many?

LANs

LAN (Local Area Network): This network covers a small area such as a school, office or a building. It’s usually set up to share files, internet and printers and to play multiplayer games. Local area networks are easy to build and maintain. The simplest LAN i9s two computers connected by an Ethernet cable (commonly referred to as “LAN CABLE”). Multiple computers can be connected to LAN using a network hub. Multiplayer games can be played by building a temporary LAN which is commonly called a LAN party.

WLAN ( Wireless Local Area Network): As the name suggests, this network provides the same kind of connectivity as LAN without the cables. It uses radio signals to communicate. Your device must be Wi-Fi enabled to connect to a WLAN.

WAN (Wide Area Network): Unlike LAN or WLAN, WAN spans a large area such as a city or a country. This is made possible by connecting smaller networks like LAN to each other. The best example of WLAN is the internet, which is the world’s biggest WAN. Besides the internet, large businesses and governments use WAN to relay to their clients and colleagues.

MAN (Metropolitan Area Networks): These networks span a large area like a city or a large campus. MANs usually interconnect a number of LANs and provide building blocks for WAN.

SAN (Storage Area Network): SAN is a type of Local Area Network (LAN) designed to handle large data transfers.

PAN (Personal Area Network): This is your very own personal network. Personal area networks typically involve a mobile computer, a cell phone and/or handheld computing device such as a PDA or an iPad. You can use the network to transfer files between your devices, sync your calendar etc. Personal area networks can be constructed with cables or wirelessly.

CAN (Controller Area Network): This is a network of microchips which can communicate with each other without a host computer. It was designed specifically for automotive applications but  is now also used in other areas such as industrial automation and medical equipment.

DAN (Desk Area Network): Desk Area Network (DAN) is an architecture for a multimedia workstation that is based around an ATM (Asynchronous Transfer Mode) interconnect. ATM is a name given to very high speed networking protocols. This architecture allows multimedia devices to be connected to the network instead of the workstation.
