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.

1. Computer Network

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.
