Suppose a program with specific input data runs in a known time on a system. The details $($input data, execution time$)$ are unimportant for this question. Now, suppose that the system design is modified in ways that affect basic attributes, like the clock rate or the average CPI for the program in question, but that the changes do not change the machine language and that the program would still execute the same sequence of machine instructions as before. For each scenario described below, determine what effect the described changes would have on the execution time of the program. In each case, the possible responses are decreased execution time, increased execution time, same execution time, and insufficient information to determine. The parts are logically independent.
