Network topology

Question 1

Peer-to-peer network

Answer 1

Data is shared directly between systems without requiring a central server. Each computer is equally responsible for providing data. It is optimal for sharing files. This is a simpler than a client server network, however there is no central device to manage security or backups

Question 2

Star network

Answer 2

Each node is connected to a central node that transfers data packets. The hub/switch looks at the destination address and transfers packets to the intended computer. It has improved security and transfer speeds , however if the central system fails, then the whole network is unstable.

Question 3

Bus network

Answer 3

The nodes are connected to a bus that transfers data packets and each computer checks the destination address while comparing the computer address. If they don’t match, it moves on but if it does, the data packet is sent to the computer. It is quick to set up which makes it optimal for temporary networks, however there is poor security.

Question 4

Token ring network

Answer 4

In networks connected in a ring or loop, a token (data packet) is sent around the ring in one direction and works like a bus network.Data collisions are avoided as data is sent in one way but to add a new node, the network must be temporarily shut down.

Question 5

Mesh network

Answer 5

Each computer is connected to every other computer. Data packets are sent to the destination address through the quickest path and there are alternative paths if one breaks down. However because the large amounts of cable it can be hard and expensive to maintain

Question 6

Client server network

Answer 6

Clients make a request to a server and a server manages it and responds. The client is completely dependent on the server to provide information, network security and backups. It allows for scalability but traffic will cause the network to slow down.

Question 7

Bus

Answer 7

A central cable which transfers all the data on the network.
