Today we’re discussing how a clock drives your computer, and how CPU clock speed works. Without a clock driving your computer’s processor, without your processor clock speed, without that little crystal, like the one you find in your watch, your computer would just not function. Computer’s rely on a constant pulsing signal to move data around and perform calculations, and it’s this pulsing signal that drives everything from your hard drive to the display on your monitor. This video aims to explain how processor speed works, how the CPU clock cycle compares to the instruction cycle, how computers moved from Hz to Khz, Mhz and eventually Ghz in the quest for more computing power, as well as what Ghz means, what Mhz means and what clock speed vs cores equates to.
