Answer
Computer 1 has a greater number of cores (4) compared to Computer 2 (2). This means that Computer 1 can better handle multiple tasks simultaneously, which is advantageous for running a 3D flight simulator that may require parallel processing.
Step 2
Identify two other parts of a computer that are not in Fig. 1, which could improve the performance of the computers.

Answer
The cache size affects performance because a larger cache allows more data to be stored closer to the CPU. This minimizes the time it takes to retrieve frequently accessed data, leading to faster processing and improved overall speed of operations.
Step 4
Identify two events that take place during the fetch-execute cycle.
