Detailed explanation-1: -phrase. The pros and cons of something are its advantages and disadvantages, which you consider carefully so that you can make a sensible decision.
Detailed explanation-2: -Yes, the two terms imply the same. ‘Pros and cons’ comes from Latin pro et contra meaning ‘for and against’. It actually means ‘the positive and negative aspects of an argument’. I would add that “advantages and disadvantages” is probably more formal that “pros and cons".
Detailed explanation-3: -con noun (DISADVANTAGE) a disadvantage or a reason for not doing something: One of the cons of buying a bigger car is that it costs more to run. You have to weigh up all the pros and cons of the matter before you make a decision.
