    This document discusses different types of network topologies. It describes bus, star, ring, tree, mesh, and hybrid topologies. For each topology, it provides details on the network design, advantages, and disadvantages. Bus topology uses a single cable to connect all nodes. Star topology connects each node to a central hub. Ring topology connects all devices in a continuous loop without a central server. Tree topology has a hierarchical structure with nodes connected to a root. Mesh topology uses point-to-point connections between all nodes. Hybrid topology combines characteristics of other topologies.

    TOPOLOGY OF COMPUTER

    NETWORK
    What is Network Topology?
    A computer network is a collection of
    two or more computers which are
    connected together to share
    information and resources.
    Types Of Topology

    Based on Based on
    geographical Architecture
    area covered
    Bus Topology

    Local Area Star Topology


    Network (LAN)
    Ring Topology
    Metropolitan Area
    Network (MAN) Tree Topology

    Mesh Topology
    Wide Area
    Network(WAN) Hybrid Topology
    Types Of Topology
    Bus Topology
    A Bus topology consists of a single cable—called a
    bus— connecting all nodes on a network without
    intervening connectivity devices
    Advantages of Bus Topology
    • Works well for small networks.
    • Relatively inexpensive to implement.
    • Easy to expand joining two cables together.
    • Used in small network.

    Coaxial
    cable

    Network Card
    Disadvantages of
    Bus Topology

    • Management costs can be high


    • Cables fails then whole network fails.
    • Cables has a limited length.
    Star Topology
    A star network is designed with each node
    (file server, workstation, peripheral)
    connected directly to a central network hub
    or server.
    Advantages of Star Topology
    • Good option for modern
    networks
    • Low startup costs
    • Easy to manage
    • Offers opportunities for
    expansion
    • Most popular topology in
    use wide variety of
    equipment available
    Disadvantages of
    Star Topology
    • Hub is a single point of failure
    • Requires more cable than the bus
    • Cost of installation is high.

    Hub
    Ring topology
    A ring network is one where all workstations
    and other devices are connected in a
    continuous loop. There is no central server.
    Advantages of Ring Topology
    • Easier to manage; easier to
    locate a defective node or
    cable problem
    • Well-suited for
    transmitting signals over
    long distances on a LAN
    • Handles high-volume
    network traffic
    Disadvantages of
    Ring Topology
    • Expensive
    • Requires more cable and
    network equipment at the
    start
    • Not used as widely as bus
    topology
    – Fewer equipment options
    – Fewer options for expansion
    to high-speed communication
    Tree topology
    • It has a root node and
    all other nodes are
    connected to it forming
    a hierarchy. It is also
    called Hierarchical
    Topology.
    Advantages Of Tree Topology
    • Extension of Bus and Star Topology.
    • Expansion of nodes is possible and easy.
    • Easily managed and maintained.
    Disadvantages Of Tree Topology
    • Heavily cabled.
    • Costly.
    • If more nodes are added maintenance is
    difficult.
    • Central hub fails, network fails.
    Mesh Topology
    It is a point-to-point connection to other
    nodes or devices. Traffic is carried only
    between two devices or nodes to which it is
    connected. Mesh has n(n-2)/2 physical
    channels to link hn devices.
    Advantages Of Mesh Topology
    • Each connection can carry its own data load.
    • Fault is diagnosed easily.
    • Provide security and privacy.
    Disadvantage of mesh topology
    • Installation and configuration is difficult.
    • Cabling cost is more.
    • Bulk wiring is required.
    Hybrid Topology
    It is the mixture of two or more topologies.
    Therefore it is called Hybrid topology. A
    hybrid topology combines characteristics of
    linear bus and star and/or ring topologies.

    Star-Wired Bus
    Advantages of hybrid topology
    • Reliable as error detecting and trouble
    shooting is easy.
    • Effective.
    • Scalable as size can be increased easily.
    • Flexible.

    Star-Wired Ring
    Disadvantages Of Hybrid
    Topology
    • Complex in design.
    • Costly.
