LAN WAN MAN PPT | PDF Report| Presentation: Before discussing Lan Wan and MAN, let us know about the Network.

Network: A network consists of 2 or a lot of computers that are coupled so as to share resources (such as CDs and printers), exchange files, or enable electronic communications. The computers on a network are also coupled through cables, telephone lines, radio waves, satellites, or infrared radiation beams.

Distinct Types of Networks:

By depending upon the area covered by the network, networks are classified as below:

Fig1: Types of Networks

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

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:

• 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.
• 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.
• The topologies included are Bus

2. Ring 
3. Star

Advantages of LAN:

Few advantages of LAN are mentioned below:

• Resource sharing
• E-mail
• Security
• Security
• Cost
• Speed

Disadvantages of LAN:

Disadvantages of LAN are mentioned below:

• Cables may break
• File server may break
• Needs administrative time
• Expensive to install

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 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
