Some minor technical innacuracies (based upon DBPisms) but overall explains the concept quite well: http://www.bansheestudios.com/stuff/timerBasedMovement.html
To take this tutorial further you could try capping the delta to match the refresh rate of the current screen resolution with a while delay wend loop.
This is a false ideal, people often hark back to the "golden era of programming" on the 16 bits and site a standardised platform as the key issue which made it great, I hate 8 Amigas - and not one of them ran at the same speed as another. Even on todays consoles you can get upgrades - perhaps not of speed particularly - but certainly of optional hardware to support.

If we would develop for consoles, there wouldn't be a need for delta etc. making things simpler.
