Which part of a computer carries out the instructions in a program?
A CPU has a clock that sends out a timing signal to keep its steps in time with each other.
Which part of the CPU actually adds two numbers together?
In which order does a CPU handle each instruction?
If two processors have the same clock speed in GHz, they must run every program equally fast.
A processor's clock runs at 2 GHz (2 × 10⁹ cycles per second). How long does one clock cycle last, in nanoseconds? (1 ns = 10⁻⁹ s)
Doubling the number of cores in a processor always halves the time any program takes to run.
Two laptops use processors from different manufacturers with very different internal designs, yet both run the same compiled program file. What makes this possible?
Pipelining overlaps the stages of the instruction cycle. Explain why this raises throughput without making any single instruction finish sooner, and name one situation that reduces the benefit and a technique that mitigates it.
