CPU
CPU is the chip inside a computer that carries out every task you ask it to do.
A kitchen cutting board sits on the counter. Every piece of food gets brought to it, chopped, and passed to the pot. The board does not store food or heat it — it just handles each piece in turn. A CPU works the same way, handling each task and passing the result along.
Explaining cpu by grade level
Your computer has a tiny chip that does all the thinking. When you click something, that chip figures out what to show you. A faster chip means your computer responds more quickly. That is why some computers feel snappier than others.
Projects that explore cpu
Every program you open and every file you save passes through the CPU as it carries out each task. You can test its role directly by adjusting the clock speed and comparing test scores. Because other parts like the backside cache also affect performance, the winner may not be the part you expect.
A faster CPU carries out each task more quickly, but it does not work alone. By swapping the CPU and RAM in a desktop computer and timing startup and game loading, you can isolate how much the processor chip contributes compared to available memory. When you measure performance with five other programs running, the results reveal whether the chip executing every instruction or the memory feeding it data has a bigger effect on speed.
