This question is an exact duplicate of:
which one of three styles is the most correct ?
1- The algorithm's running time.
2- The algorithm running time.
3- The running time of the algorithm.
1- The Transmitter's energy consumption.
2- The Transmitter energy consumption.
3- The energy consumption of the transmitter.
Honestly, I am confused about them :), I am not sure what the difference is. Is there any grammar for such situation? Thank you in advance.
