    Study Notes

    Examining the Basics of a Network Layout

    • Topology refers to the physical layout and communication method of network components, including computers and cables.
    • Physical topology deals with cabling arrangement, while logical topology pertains to the data path across the network.
    • The choice of topology significantly influences network performance, growth, and equipment selection.

    Understanding Standard Topologies

    • Network designs generally utilize three main physical topologies:
      • Bus Topology: Computers connected along a single cable segment.
      • Star Topology: Computers connect via a central hub.
      • Ring Topology: Computers form a closed loop.
    • Logical topologies depict data travel paths and can vary from physical topologies; for example, logical bus topologies are often implemented as physical stars.

    Communication on the Bus Topology

    • The bus topology offers low fault tolerance due to its single-cable structure, where a failure can disrupt the entire network.

    Signal Propagation

    • Communication in bus topologies involves computers sending signals as electrical pulses traveling in all cable directions.
    • Signals continue until they weaken or are absorbed by a device, a process known as signal propagation.

    Logical Bus Topology

    • A logical bus topology allows all computers to address and transmit data collectively, with only the intended destination accepting the data.
    • Performance can suffer due to shared transmission time among all units on the network.

    Physical Ring Topology

    • In a ring topology, data travels sequentially from one node to the next until reaching its destination.
    • Token passing is a common method for data transmission in this structure.

    Logical Ring Topology

    • Modern logical ring topologies often utilize smart hubs that can detect and remove failed computers from the network ring automatically.
    • This design effectively shares network resources among devices, ensuring fair access.

    Physical Star Topology

    • The star topology enables ease of management and troubleshooting, as failures in one cable do not affect the entire network.
    • Logical bus and ring topologies can both be implemented using a physical star configuration, offering versatility in network design.
