Network Topologies Types
A pattern in which nodes are connected to a local area network (LAN) or other network via links.
A network layout in which there is one main trunk, or backbone, that all the various computers and network devices are connected to.
Topology where the computers are connected on a loop or ring. Data flows in one direction only.
A topology with one central node that has each computer or network device attached to the central node. All data first goes into the central node and then is sent out to its destination.
Advantages of the bus topology
-Easy to extend
-Simple layout uses the least amount of cable
-Best for handling steady (even) traffic
Advantages of the ring topology
- data is transferred quickly, as data only flows in one direction so there are no (or least risk of) data collisions
- cheapest to set up
Advantages of the star topology
-Cable layouts are easy to modify and centralized control makes detecting problems easier
-Nodes can be added to the network easily
-Effective at handling short bursts of traffic
- Fastest to transmit data
- Most secure for sending data
- Most robust (i.e. can still keep running if one node/cable breaks)
- Needs technicians to set up / maintain
Advantage of all topologies
Easy to add extra nodes - If the networks are small, extra nodes can easily be added to all topologies.
(However, as a star network grows it becomes more difficult to keep adding additional nodes).

A point of connection within a network.
A device that connects devices (computers, printers, etc.) together by using its ports.
A device that forwards data between computer networks.
A computer networking device that connects network segments together.
A thick steel rope made of strands of wire twisted together which connects all devices together.
When two computers send data at the same time and the sets of data collide.
A device attached to the end-points of a bus network. The purpose of it is to absorb signals so that they do not reflect back down the line.
