Helpdesk: Evaluating Your CPU and RAM (Ch.6)

If I buy the fastest processor, does that always ensure the best performance for my computer?

Not necessarily. A computer's overall performance depends on many other factors than just the processing speed.

What does the term "GHz" mean?

Processor speed is measured in gigahertz, or GHz, which refers to the number of machine cycles per second that the processor goes through. So, for example, a 3 GHz processor performs 3 billion machine cycles per second.

What is RAM? What kind of data is stored in RAM?

RAM is the computer's temporary storage space. Data stored in the RAM is volatile.

Where is the CPU located?

The CPU is located on the motherboard.

Is there a limit to how much RAM I can add to my computer?

Yes. Every computer is designed with a maximum limit on the amount of RAM it can support.
