Name two reasons why you would use STO or UTP?
Keeping costs low
An easy installation with simple computer connections is required
Why wouldn’t you use UTP or STP?
High level security needed and high data integrity
Data transmitted far and fast
How fast is fibre optic?
100 Mbps to 1 Gbps
When to use fibre optic
High speed/ security and long distance
When not to use fibre optic
Cost
Cannot install or connect devices to
Expand IEEE
Institute of Electrical and Electronics Engineers
Expand MAC

5 advantages of star topology
Easy setup and maintain Problem with one computer or cable doesn't affect others Adding or removing node causes no upsets Easy to expand Most common
3 disadvantages of star topology
If switch breaks, network fails
Large amount of cabling
Switch adds to cost
3 advantages of bus topology
Less cable than start therefore reducing cost
No switch therefore less cost
Easy to extend
4 disadvantages of bus topology
Faults difficult to trace
Fault in main cable shuts dow network
Congestion
Adding node can disrupt network
What two topologies make up a tree topology?
Bus and star
Expand FDDI
Fibre Distributed Data Interface
