2.10 Network Topologies

2.10.1 Physical Topology

A network topology defines how computers, printers, network devices, and other devices are
connected. In other words, a network topology describes the layout of the wire and devices as well
as the paths used by data transmissions. The topology greatly influences how the network works.
Networks can have both a physical and a logical topology. Physical topology refers to the physical
layout of the devices and media, as shown in Figure 2-20.

Physical topologies that are commonly used are:

• Bus

• Ring

• Star
• Extended star

• Hierarchical

• Mesh

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.
