No, you are getting Hz and resolution mixed up.
Resolution is the number of pixels on the screen. The greater the resolution, the smaller everything is. As you increase the resolution, the size of everything decreases. LCD's (Liquid Crystal Display) have a native resolution, and CRT's (Cathode Ray Tube) don't. A native resolution is the number of matrixes (cells or pixels) on a screen. If the native resolution is 1024 x 768 then there are 1024 cells, or pixels, across the screen and 768 cells, or pixels, down the screen. On an LCD, if you decrease the resolution, below the native resolution, it displays one pixel using multiple cells, degrading the image. If you increase the resolution beyond the native resolution it has to use one cell to display multiple pixels. Your CRT monitor sprays pixels on the back of a glass screen.
Hz, or Hertz, is the frequency the monitor runs at. It is how fast your monitor refreshes itself. LCD's run at a lower frequency, so the refresh rate is slower. That is why they look blurry when things move fast, at times. Hertz is the number of times each pixel is refreshed in a second. If you have a monitor running at 60Hz, then the pixels refresh 60 times a second. If you have a 100Hz monitor, then the pixels refresh 100 times a second.
You then have the 21 inch monitor, which is either the monitor size, or the viewable area. The viewable area being what you see behind the glass tube, not the plastic casing. Most likely 21 inches is the whole monitor, including the casing. You monitor hooks up with a VGA cable, most likely. It could also hook up with a DVI connection. Aspect Ratio or orientation is landscape or portrait. Maximum Resolution is the max. number of pixels you can fit on the screen.
These aren't the best articles, but I typed everything up and went looking for articles quickly.

Sorry, double post.
You know, what I find funny is that people who never bother changing it to a higher rate usually get so used to it that they don't see the flickering anymore I've gone to several friends' houses before, said "Don't you ever notice your monitor flickering wildly like that?", and none of them can see it. Odd.
