The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. It includes devices housed in a single room to millions of devices spread across the world. Following are the popular types of Computer Network:

The full forms of types of network are mentioned below: 

         LAN – Local Area Network

      MAN – Metropolitan Area Network

      WAN – Wide Area Network

      PAN – Personal Area Network

Next Now, let us discuss each of them in detail:

Local Area Network (LAN):

A local area network (LAN) could be a cluster of computers and associated devices that share a standard communications line or wireless link to a server. Typically, a local area network encompasses computers and peripherals connected to a server among a definite geographic region like a workplace or a billboard institution. Computers and different mobile devices use a local area network affiliation to share resources like a printer or network storage.

A local space network could function few as 2 or 3 users (for example, in a very small-office network) or many hundred users in a very larger workplace. Computer network networking contains cables, switches, routers and different parts that allow users hook up with internal servers, websites and different LANs via wide area networks.

Features of LAN are:

The important points related to LAN are mentioned below:

•   LANs are capable of terribly high transmission rates (100s Mb/s to G b/s).

•   Nodes in a LAN are joined at the side of an exact topology.

•  LAN’s will be either wired or wireless. Twisted pair, coax or fiber optic cable will be utilized in wired LAN’s.

•   Every LAN uses a protocol –a set of rules that governs, however, packets are designed and transmitted.

Metropolitan Area Network (MAN):

A metropolitan space network (MAN) could be a network that interconnects users with pc resources in an exceedingly geographic space or region larger than that lined by even an oversized local area network (LAN) however smaller than the realm lined by a wide area network (WAN). The term is applied to the interconnection of networks in an exceedingly town into one larger network (which might then conjointly provide economical affiliation to a large space network). it’s conjointly accustomed mean the interconnection of many native space networks by bridging them with backbone lines. The latter usage is additionally generally mentioned as a field network.

Examples of metropolitan area networks of varied sizes are found within the metropolitan areas of London, England; Lodz, Poland; and Geneva, Switzerland. massive universities conjointly typically use the term to explain their networks. A recent trend is that the installation of wireless MANs.

Wide Area Network (WAN):

A wide area network (WAN) may be a telecommunications network or network that extends over an outsized geographical distance. Wide area networks are typically established with hired telecommunication circuits. Business, education and government entities use wide area networks to relay information to employees, students, clients, buyers, and suppliers from numerous locations across the planet.

In essence, this mode of telecommunication permits a business to effectively perform its daily performs no matter its location. the net is also thought of a WAN. Related terms for alternative kinds of networks are personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) that are sometimes restricted to an area, building, field or specific metropolitan area respectively.

• List of WAN Types:

  • • • •   SD- WAN

        •   25

        •   SONET

        •   Leased line

        •   ISDN

        •   Frame Relay

        •   DSL

        •   Dial-up

        •   Cable modem

        •   ATM

What are the few real applications of LAN WAN YAN?

Allow us to mention a few amazing applications of this technology below:

 Connecting Computers

The major use of this system is to connect the computers in a pretty large area.

 Connecting Cities
