Transcript

  • 1. T OPOLOG Y
  • 2. Introductio n :
    • A topology is concerned with the physical arrangement of the network components.
    • The connection between the devices on a local area network.
    • three basic network topologies are
    • the bus, the star, and the ring.
  • 3. Bus T opology
    • It connects each computer (node) to a single segment trunk.
    • A ‘ trunk ’ is a communication line, typically coax cable, that is referred to as the ‘bus .’ 
    • The signal travels from one end of the bus to the other.
    • signals are broadcast to all stations
  • 4. Local bus
    • each computer is attached directly to the backbone in a daisy-chain configuration by means of a "T" connector .
    • Peer-to-peer networks are often configured as a local bus.
  • 5. Regular Bus
    • In a regular bus , each computer is attached to the cable segment (called a backbone) by means of a drop cable (a shorter cable connecting the computer to the backbone).
  • 6. S tar T opolog y
    • All of the stations in a star topology are connected to a central unit called a hub
    • offers a common connection for all stations on the network
    • Each station has its own direct cable connection to the hub .
    • more cable is required than for a bus topology.
    • This eliminates the single point of failure problem associated with the bus topology.
    • the signal is split and sent out simultaneously to all stations.
    •  
  • 7. Ring Topology
    • consists of a set of stations connected serially by cable
    • other words, it’s a circle or ring of computers.
    • There are no terminated ends to the cable; the signal travels around the circle in a clockwise
    • this topology functions logically as ring, it is physically wired as a star
  • 8.
    • The central connector is not called a hub but a Multistation Access Unit or MAU .
    • all the stations are individually connected to a central location.
    • In a ring topology, the center is called a MAU.
    • The ring actually consists of a continuous circuit
    • Signals are passed along the circuit and accessed by stations in sequence
