Answer and Explanation:
Reliability is important because if the service lacks lacks reliability this could mean losing a packet or acknowledgement which then requires retransmission.
Delay can be tolerable in different degrees by applications, for example online chatting or conferences need to have the minimum delay possible.
Jitter is the variation in delay for packets belonging to the same flow.
High Jitter: difference between delays is large
Low jitter: difference between delays is small.
Bandwidth depends on the application. In video conferences, for example, there is a need to send million of bits per second to refresh a colour screen while sending a email may not reach even a million.
Digital vs Analog Audio is completely personal preference and there is no clear winner on which is better.
But there are some pros and cons about both, Analog sometimes distorts when playing and can be easily scratched and ruins the grooves. Analog is believed to be the true representation of the sound when it was recorded. Digital is not the actual recording of the sound, it's actually a combination of binary code. It is also sometimes mixed or remastered in Digital and sounds a bit different to make it sound better. It also depends on the system you are listening it from. You could have a horrible Digital system its playing through and an amazing Analog system playing, of course the Analog system will sound better in that case. Some believe that Digital is on par to overtake Analog in the "true picture of sound" category but some also say Analog will forever be the best at playing sound and Digital will always be the alternative.
But, in the end it's all personal preference and the pros and cons don't overweigh to make one better than the other.
