That flicker you see is from the CRT redrawing the image. (You don't get that problem on LCDs or on monitors that have their refresh rates cranked up.) The human eye can't catch the refresh, but a camera can.
Oh, and hertz is just "cycles per second", and can therefore be used to describe anything that's periodic in nature: monitor vertical/horizontal refresh rates (though we usually use kHz for the former), CPU speeds, radio frequencies, jbone's humor quality, etc.
As far as what frame-rate a computer (program, I presume) displays: That's the frame-rate that your program is achieving -- how many complete frames (as defined by the image width+height) the program has been able to write to the video buffer per second (as defined by the internal clock). It has nothing to do with what rate your display device refreshes at, although if your display device refresh rate is too low to keep up with what the display adapter is blasting out, you'll get odd, and rather eye-straining, artifacts.
