quartz crystalquartz crystal
- A small crystal of quartz accurately cut along certain axes so that it can be vibrated at a particular frequency, used for its piezoelectric properties to produce an electric signal of constant known frequency.
- Any of several crystalline forms of quartz.
quartz crystal - Computer Definition
A slice of quartz ground to a prescribed thickness that vibrates at a steady frequency when stimulated by electricity. The tiny crystal, about 1/20th by 1/5th of an inch, creates the computer's heartbeat. Without the quartz crystal, there would be no computers as we know them today! See clock and MHz.
