3.3 - Network Characteristics
Peer-to-Peer
Client Server
Mesh Network
Bus Network
Ring Network
Star Network
Each computer is linked to one another. Instead of using a dedicated server, they send data packets through and between each other.
Pros:
- Each user sets access rights, so ICT specialists are not needed
- One PC failing does not bring down the entire network
Cons:
- The more people log in, the worse performance gets
- Cannot perform a central file backup
Files are not stored on the computers, but rather on a server, which provides services to each computer and client.
Pros:
- All files stored centrally
- If some PCs fail, files will still be available
Cons:
- Requires a network OS
- Servers are expensive
Pros:
- Easy to install
- Cheap, as it doesn't require much cabling
Pros:
- Data is transferred quickly, because it only travels in one direction
Cons:
- Requires skilled ICT staff to manage
- Extremely expensive to set up
Cons:
- Adding more workstations will slow the whole network down, due to data collisions
- All data passes through the main cable, creating a security risk
Pros:
- Reliable
- High performance
Cons:
- Expensive
- If the hub/switch fails, the whole network goes down
Cons:
- If any cable or device fails, the whole network goes down
Pros:
- A broken cable or computer doesn’t affect the rest of the network
- Extra computers do not slow down the network
