(bps). It’s a standard metric for determining how quickly data is transported from one location to another. For example,
                 your Internet service provider may offer a 4Mbps maximum data transmission rate.

                   1.3 NETWORK TYPES

                 Networks are the backbone of today’s business, used for everything from accessing the Internet to printing a document
                 and to downloading an attachment from an email. They can refer to anything from a few gadgets in a single room to
                 millions of devices distributed across the globe, and they can be classified according to their purpose and/or size. On
                 the basis of geographical span, the network can be broadly categorized as follows:


                                                          Types of Computer Network






                              PAN                      LAN                     MAN                      WAN

                 Let us understand each one by one.

                 Personal Area Network (PAN)

                 A PAN is the simplest and most basic sort of network, consisting of a wireless modem, one or more computers, phones,
                 printers, tablets, and other devices that revolve around one person in one building. These networks are commonly
                 found in small offices or homes, and they are controlled by a single person or organisation using a single device. The
                 range of PAN is 10 meters.





















                 Local Area Network (LAN)

                 LANs are one of the most commonly used networks, as well as one of the most
                 prevalent, unique, and basic forms of networks. These networks allow groups
                 of computers and low-voltage devices to share information and resources over
                 a radius of up to 1 KM (inside a building or between two or three buildings near
                 each other). This type of network is generally maintained by an organisation.
                 Its speed ranges from 10 Mbps to 1 Gbps.

                 Metropolitan Area Network (MAN)

                 A MAN is larger than a LAN or we can say that it is a combination of multiple LANs. A single entity or a group of persons
                 or organisations may own a MAN. It is used to create connections within a city and can cover a radius of up to 50 KM.
