Ltc310 - Advantages and disadvantages of the Mesh, Bus, Ring and Star Topologies:
These are a type of Network Topology that refers to the different layers and layout of a network design which various in their uses, the elements of network in which are interconnection to function as demand by particular need.

Ltc 310 - These Network Topology can be either or physical topology or logical topology. Topology simply means the overall structure/ design or shape of the network.
Mesh topology: In this type of topology the node has dedicated point to point links which function in order for the next node within the network to operate. This means each link carried a message that can be transmitted between these two nodes to which it is connected to. Say for example if N is the total number of nodes in the network, the number of links to connect to these nodes in mesh=N (N-1)/2. Each node will have (N-1) I/O ports to connect to every other node in the network.
Ntc361 - Advantages:
  * There will be no traffic problem as there are dedicated links, linking one to another within each network.
  * Will be strong as failure of one link does not affect the entire system.
  * Better Security as data travels along a dedicated line, one node to another.
  * Points to point links make fault identification easier.
Ntc 361 - Disadvantages:
  * The hardware can be costly because it is dedicated link for any two nodes and each device should have (n-1) I/O ports.
  * There is mesh of wiring which can be difficult to manage.
  * Installation is complex as each node is connected to every node within the network
Bus topology: this type of topology is referring to a long backbone of cable that is used to link all device/ node in the network together. Each link will have a drop line and taps that are connected to the final node in the backbone.
