Introduction

A network topology is the physical and logical arrangement of nodes and connections in a network. Nodes usually include devices such as switches, routers and software with switch and router features. Network topologies are often represented as a graph.

Importance of network topology

• it help us better understand the networking concepts.
• it also helps reduce the operational and maintenance costs such as cabling cost.
• it is factor in determining the media types to be used to cable network .
• Error or fault detection is made easy using network topologies.
