Types of Network
The various types of networks are as follows :-
1. Local Area Network [ LAN ]
It is a network that connects computers and devices in a limited geographical area such as home, school,computer laboratory, office building or closely positioned group of building. A LAN is useful for sharing resources like files, printers, games or other applications.
A LAN in turn often connects to other LANs and to the Internet or other WAN. Most local area networks are built with relatively inexpensive hardware such as Ethernet cables, network adapters and hubs.
2. Metropolitan Area Network [ MAN ]
It is a computer network that usually covers a larger area than a LAN. e.g. a network that connects two offices in a city, a neighborhood area, etc. A MAN is a large computer network, spanning a physical area larger than a LAN but smaller than a WAN. A MAN is typically owned and operated by a single entity such as a government body or large corporation.
3. Wide Area Network [ WAN ]
It is a computer network that covers a large geographical area such as a city, country or spans even intercontinental distances, using a communication channel that combines many types of media like telephone lines, cables, etc.
WANs often connect multiple smaller networks, such as Local Area Networks (LANs) or Metropolitan Area Networks (MANs). The world's most popular WAN is the Internet.
4. Personal Area Network [ PAN ]
PAN refers to a small network of communication. These are used in a few limited range, which is in the reach-ability of individual person. It generally covers a range of less than 10 meters and can be constructed with cables or wirelessly. Few examples of PAN are Bluetooth, wireless USB, Z-wave and Zig Bee, etc.
5. Virtual Private Network [ VPN ]
VPN is a technology that s gaining popularity among large organizations that use the global Internet for both intra and inter-organisation communication. VPN is a network that is private but virtual. It is private because it guarantees privacy inside the organisation. It is virtual because it does not use real private WANs; the network is physically public but virtually private.
