Beginner Topic 2 of 50 Computer Networks
Network Topologies
Layouts such as bus, star and mesh.
How it works
Topology is the layout of links: bus, ring, star (common in Ethernet), mesh (resilient but costly) and tree. It affects cost, fault tolerance and performance.
Where it is used
Star LANs around a switch; mesh in backbone networks.
Common pitfall
A single central device in a star is a single point of failure.
Where it fits in the course
Network Topologies is topic 2 of 50 in Computer Networks, rated Beginner. It follows What is a Network. The next topic is LAN, WAN and MAN.
