Question 1: What does clock speed measure in a CPU?
The physical size of the CPU
The number of tasks a CPU can handle
The number of FDE cycles every second
The amount of power the CPU consumes
Question 2: How does cache size affect CPU performance?
More frequently used instructions stored
Cache size has no impact on performance
Smaller cache increases CPU efficiency
Cache size only affects gaming performance
Question 3: Why might a CPU with multiple cores perform better than a single-core CPU?
More cores = more tasks
Single-core CPUs are always faster
Cores only affect graphics performance
More cores decrease power consumption
Question 4: Which one is the best computer?
2 cores = 4 GHz
2 cores = 3 GHz
4 cores = 0.1 GHz
1 cores = 4 GHz
Question 5: In a scenario where a CPU has high clock speed but low cache size, what might be a consequence?
Increased performance due to faster processing
Frequent delays in accessing data
Reduced power consumption
Better multitasking abilities
