Network topologies
Mesh topology
Data is transmitted by routing (routing logic to work out the shortest path) or flooding (data sent to all nodes in the network).
-
-
-
-
-
Difficult to manage, specialised IT staff are needed to manage the network
-
Star topology
-
Every device in the network is directly connected to the switch and indirectly connected to the other nodes.
-
If any non central node goes down, the rest of the network can stay up.
If the central switch goes down, so does the whole network.
-
-
Peer to peer
This is when a network is made of a collection of linked computers, and no server.
-
-
-
Central backup cannot happen, computers must individually backup data
-
Client server
-
Server can be accessed at any time to edit, receive and access files
-
-
Servers are expensive, and so if hiring and paying iT staff
-
Ring topology
Computers are connected in a circular format, where each computer is connected to two others.
-
-
-
Very vulnerable to failure, difficult to make changes
-
Bus topology
-
-
Simple layout for smaller networks, can be run using a single cable.
-
-
Hybrid topology
-
-
Depending on the different topologies, they can become extremely complex.
