WHERE exactly is the CPU *CLOCK* LOCATED? Is it INSIDE or OUTSIDE the CPU? I mean, is it inside or outside the CPU chip? Every where I read, the CPU clock's operation is mentioned, but NEVER where the clock is exactly located!
Is is sometimes referred to as the SYSTEM CLOCK (?), implying it is OUTSIDE the CPU. But then HOW can each DIFFERENT CPU be said as having a certain speed, if it's speed can be "controlled" by an "outside" clock?
