Network Topologies

TOPOLOGIES

There are two types of Local Area Network Topologies. They fall into the following categories:

·         Logical topology

·         Physical topology

Logical Topologies

When interviewing Warren on 25 August 2015, (DUT student) stated that:

“A logical topology is a concept in networking that defines the architecture of the communication mechanism for all nodes in a network. Using network equipment such as routers and switches, the logical topology of a network can be dynamically maintained and reconfigured. Logical topologies contrasts with physical topologies, which refer to the physical interconnections of all devices in the network.”

A more condensed and precise definition of a logical topology is that the term logical topology refers to the way data is transmitted between nodes. A logical topology may also be called a network transport system. (Y.Xin et al. 2003: 904).

There are two most popular logical topologies which are:

·         Broadcast (Ethernet)

·         Token Ring
