BUS Topology

• Bus Topology

  Also known as line topology, it is a type of network topology where all devices on a network are connected to a single cable, called a bus or backbone
• Bus Topology

  • Bi-directional data transmission
  • Uses twisted-pair or coaxial cable as the bus (backbone cable)
  • Devices connected to the cable via a tap or connector
• How Bus Topology Works

  1. Single central cable serves as the shared communication medium

  2. Terminators used at each end of the cable to absorb signals

  3. Prevents signal reflection and interference
• Data Transmission in Bus Topology

  1. Device broadcasts data onto the cable

  2. Only the device with matching destination address processes the data

  3. CSMA/CD protocol used to manage data transmission and avoid collisions
• Advantages of Bus Topology

  • Less cabling
  • Easy to install
  • Less expensive
  • Fast data transfer
  • Upgradeable
  • Scalable
  • Efficient
  • Reliable
• Disadvantages of Bus Topology

  • Core failure
  • Low security
  • Limited speed
  • Not suitable for large networks
