Shutter cycle
A shutter cycle is the process of the shutter opening, closing, and resetting to where it is ready to open again. The life-expectancy of a mechanical shutter is often expressed as a number of shutter cycles. Most digital cameras save the shutter cycle information along with the photos, which contains valuable information such as shutter speed, aperture, and shutter count. There are multiple websites and applications to access the Exif data.
