Is this just in the context of Ethernet / LANs?

There's some good information on these from Cisco:
Coaxial - http://www.ciscopress.com/articles/a...31276&seqNum=2
Cat5e (UTP) - http://www.ciscopress.com/articles/article.asp?p=31276
Comparison - http://www.ciscopress.com/articles/a...31276&seqNum=4

Think about - Cost, Max distance, Max throughput, Susceptibility to Electromagnetic Interference.

Also remember that LANs connected using Coaxial cable are usually configured in a Bus topology (i.e. like a daisy chain, or christmas lights), so aside from the fact that all nodes on the network share the same physical bus (no dedicated link between a Node and Switch/Hub), when any one of the links breaks, the entire network stops working -- you need to test each link until you find the one that's broken. (It's the same principle as christmas lights in a serial circuit - a bulb blows and you have to manually test every single lightbulb until you figure out which one is broken).

Cat5e generally involves a Star topology via a hub or switch - i.e. all Nodes connected to the switch/hub, so if any of the links fail, it only breaks for that node, it doesn't break the whole network. (Obviously the switch/hub is still a single point of failure).

Cat5e (Ethernet) cables are protected against internal interference
Coaxial cables use shielding to protect against external interference

You won't be asked to name disadvantages of the cables but, of course, you could invert the statement above to get negatives (Eg. Cat5e cables aren't protected against external interference as well)
