In easy language, a network can be termed as a collection of computers and devices connected to each other to assist communication for sharing data and resources with other computers. Networks can be of different types, here are some of the commonly used network types.
- Personal Area Network: This is the most basic network type which is used very commonly by almost every individual. We use this type of network at our homes too like connecting a printer with the computer or a fax machine with the computer. This kind of network can be a wired or wireless network.
- Local Area Network: Local Area Network or LAN is basically used in offices, schools and cyber cafes. This kind of network is used to connect computers with computers using Ethernet technology. LAN is generally used within the same building area and each device or computer is treated as a node.
- Metropolitan Area Network: This kind of network generally connects two or more LANs together within a city or a town. Routers, hubs and switches are used to create MAN.
- Wide Area Network: Wide Area Network or WAN is used to connect larger geographical areas like cities and even countries. Communication channels like telephone lines and air waves are used to create connectivity under WAN.
- Intranets and Extranets: Intranet is a set of networks using Internet protocol to communicate with each other. It is said to be the internal network of an organization and generally will have a web server to provide information to users. Extranet is referred to as a network connection which is open to customers and clients outside the organization. It can be Wan or MAN but with at least one external connection.
