  • Welcome pageTell about the topic.
  • What LAN is?
  • The pictorial representation of LAN is shown.
  • Networking software differs from software applications in that the software does not perform tasks that end-users can see in the way word processors and spreadsheets do. Instead, networking software operates invisibly in the background, allowing the user to access network resources without the user even knowing the software is operating
  • A leased line is a service contract between a provider and a customer, provider agrees to deliver a line connecting two or more locations in exchange for a monthly rent (hence the term lease) Private Circuit“1.) there are various nodes used in the network through which the signals are passed from one system to another.2.) number of nodes are available between two devices and hence multiple paths are available to pass a signal.telephony systems.4.) transmission of audio signals and not suitable for data transmission.Packet Switching:the data is sent over the network in the form of packets i.e. a large unit of data items wrapped into a single bigger unit.the packets follows the same path that is defined for them before passing into the network.4.) It is best used for sending data over the network and audio and video signals can also be sent over the network in the form of packets.

    • 1. WelcomeLAN & WANPresented by: University roll no. – 09123005045 ID no.- EIE/09/07
    • 2. CATEGORY OF NETWORKS LAN (local area network) MAN (metropolitan area network) WAN (wide area network)
    • 3. LANLocal area network.small geographic area (e.g. room, office).controlled by one administrative authorityusually high speedalways shared
    • 4. Pictorial representation of LAN :-
    • 5. ADVANTAGES OF LAN expensive hardware can be shared e.g. laser printer. users can access the same files. messages can be sent between users. a single Internet connection can be shared among many users. network software is cheaper than buying individual packages.
    • 6. WAN Wide area network. WAN covers a large geographical area. Crosses metropolitan, regional, or national boundaries. Uses routers and public communications links. e. g. Internet. Used to connect LANs and other types of networks together. Option for WAN connectivity 1. Leased Line 2. Circuit switching 3. Packet switching
    • 7. Pictorial representation of WAN :-
    • 8. ADVANTAGES OF WAN These are similar to those of LANs except the scale of sharing. Covers a large geographical area so long distance businesses can connect on the one network. Shares software and resources with connecting workstations. Messages can be sent very quickly to anyone else on the network. Share information/files over a larger area.
    • 9. LAN & WAN COMPARISON LAN WAN Small area covered  Large area covered Use public  Use public communication links communication links Usually a low speed  Usually fast speed Uses Wi-Fi, Ethernet  Uses optic wires, cables microwaves, satellites
