Logical topology defines how the medium is accessed by the hosts for sending data. The
following sections describe different types of physical and logical topologies.

2.10.1.1 Bus Topology

Commonly called a linear bus, a bus topology connects all the devices using a single cable,
see Figure 2-21. This cable proceeds from one computer to the next like a bus line going through
a city.

Figure 2-21 shown a Bus Topology of Network Devices

With a physical bus topology, the main cable segment must end with a terminator that
absorbs the signal when it reaches the end of the line or wire. If there is no terminator, the
