Introduction

v

  vThe way in which constituent parts are interrelated or arranged.

  vThe mapping of a LAN design is called Topology.

TYPES OF TOPOLOGIES

  v Star topology

  v Bus topology

  v Ring topology

v Mesh topology. 

Bus topology 

  vA bus topology is a topology for a Local Area Network (LAN)

  vConnected to a single cable

  vHas two endpoints

  vAlso called linear bus Topology

  vSends a date in one direction

Linear Bus Topology

AdVANTAGES 

  vIts less cost-effective.

  vUsed in a small network.

  vEasy to expand  joining two cables together 

DISADVANTAGES

  vIt can be difficult to identify the problems if the whole network goes down.

  vIt can be hard to troubleshoot individual device issues.

  vBus topology is not great for large networks.

  vTerminators are required for both ends of the main cable.

  vAdditional devices slow the network down. 

Star topOLOGY

  vAll the nodes are connected to a single hub

  vEvery node has its own connection to hub

  vCan connects a node with optical fiber

v

advantages 

  vEasy to manage and maintain the network because each node require separate cable.

  vEasy to understand any problem because every node or computer has its own connection to the hub

  vEasy to extend the other node and  not create any disturbance

vDue to Hub device network control and management is much easier. 

disadvantages

  vRequires more cable length than a linear topology.

  vIf the hub, switch, or concentrator fails, nodes attached are disabled.

  vMore expensive than linear bus topologies because of the cost of the hubs, etc.
