How many seconds does it take for a computer to execute a single instruction?

anonymous · Answer

a typical desktop.

anonymous · Answer

this depends on how fast said computer is, is this for STATS?

mathmate · Answer

That depends on which computer and which instruction set.
The no-op executes for 1 cycle.  All the other ones are instruction-set dependent.

anonymous · Answer

how faaaaaast out computers are!

mathmate · Answer

Very true, that is why today's chips are so minute, just in order to reduce the time lag when electrons go from one chip to the other.  That is also responsible for the high concentration of heat generated, hence cooling problems.  It's mind-boggling!
