Networks Flashcards
Peer to peer
The peers are computer systems which are connected to each other via the internet
Files can be shared directly between systems on the network without the need of a central server
Client server
A mode of communication between multiple computers on a network that distinguishes one or more clients on the server.
Each client software can send requests to a server
Bus
Bus topology uses one main cable t which all nodes are directly connected.
One computer in te network typically acts as as the computer server
Bus topology advantages
It is easy to connect to a computer or pheripheral device
The cable requirements are relatively small, resulting in lower cost
Bus topology drawbacks
If the cable breaks then the entire network goes down
This type of network is difficult to troubleshoot. Due to this bus is not used for large networks, such as those covering an entire building due to the above points
Star topology
Each computer is connected to a central hub using point to point connection.
Advantages of star
It is very popular because the startup costs are low
It is also very easy to add new nodes to the network
If one of the connections between à imputer and the HUB fails, the other connections remain intact. Very robust
Star disadvantages
If the central hub fails however, the entire Network goes down
Requires more cable then bus topology and is therefore more expensive
Ring topology
The computers in the network are connected in a circular fashion and the data only travels in one direction
Each computer is directly connected to the next forming a single pathway for signals through the network
Advantages of ring
Easy to install and manage due to it being more simple compared to the other networks
Easy to pinpoint problems in the network ^^
Good for high volume traffic as every computer can act as a booster of the signal
Drawbacks of ring
Adding computers to the network is cumbersome
If one computer fails then the entire network goes down
Mesh topology
Every node has a direct point to point connection to every other node.
Advantages of mesh
All of the connections are direct therefore the network can handle very high volume traffic.
Data travels along a dedicated connection, therefore is highly secured
Drawbacks of mesh
Requires a lot of cables therefore making it expensive
Many connections are redundant due to several paths for data to travels through
