This document discusses different types of computer networks. It defines a computer network as a group of connected computers that share information and communication through common protocols. There are several types of networks including local area networks (LANs) that connect computers in a small area like a building, personal area networks (PANs) that connect devices within 10 meters of a person, metropolitan area networks (MANs) that connect local networks within a city or town, and wide area networks (WANs) that connect multiple LANs or MANs across a large geographic area. Each network type has different characteristics regarding size, connectivity range, and usage.

- 2. Computer Networks? A group of computers which are connected to each other and follow similar usage protocols for the purpose of sharing information and having communications provided by the networking nodes is called a Computer Network. A network may be small where it may include just one system or maybe as large as what one may want. The nodes may further be classified into various types. These include: Personal Computers Servers Networking Hardware General Hosts
- 3. Networking can be classified into three types Types of Computer Networks Topology Interpreters
- 4. Types of Computer Networks
- 5. Types of Computer Networks LAN (Local Area Network) PAN (Personal Area Network) MAN (Metropolitan Area Network) WAN (Wide Area Network)
- 6. LAN Systems connected in a small network like in a building or a small office It is inexpensive It uses Ethernet or Token-ring technology Two or more personal computers can be connected through wires or cables acting as nodes Transfer of data is fast and is highly score
- 8. PAN The smallest computer network Devices may be connected through Bluetooth or other infra-red enables devices It has a connectivity range of upto 10 metres It covers an area of upto 30 feet Personal devices belonging to a single person can be connected to each other using PAN
- 10. WAN WAN is a wide area network that covers a large geographic area consisting of two or more LANs or MANs. A WAN is a group of local-area networks (LANs) or other networks that communicate with one another. This network is widely used to aid communication, the sharing of information, and more between devices. The first WAN was designed by the U.S. Air Force in the late 1950s
- 12. MAN It is a computer network that connects multiple local area networks within a metropolitan area It could be a single big city, a town, multiple cities, or a building. MAN stands in between LAN (Local Area Network) and WAN (Wide Area Network) It is larger than LAN but smaller than WAN. MAN is specially set up to bestow high-speed connectivity to the consumers.
