Overclock

Part of speech: verb

Definitions

1. The practice of modifying a computer's processor to exceed its standard operational speed, thereby enhancing processing capability
2. The act of increasing the clock rate of a computer's CPU to boost performance, resulting in faster processing speeds and enhanced computational power
3. This technique involves adjusting the timing parameters of a computer's processor to surpass its predefined limits for improved performance and efficiency

Etymology: "Overclock" is a straightforward compound: the prefix "over-," meaning beyond or in excess, joined to "clock," which here refers to the timing signal that sets the pace of a processor's operations. The idea is literal. A processor runs in step with a clock pulse, and raising that pulse rate makes it complete more operations per second than its manufacturer specified. The "clock" half is the more interesting part. Early computers were built around a central oscillator that ticked at a fixed rate, and every component synchronised to it. Pushing that tick faster was a natural way to squeeze out more performance, so the verb naturally took the "clock" that already named the timing signal. Enthusiasts began doing this deliberately, which is why the practice grew into a word of its own.
