Refresh rate - The refresh rate is the rate at which the image on the monitor
screen is rewritten to the screen. A fast refresh rate helps keep the image
from flickering.
Resolution - The resolution is the sharpness or clarity of the image on the
monitor screen. Resolution is measured by the number of pixels the screen
can display. For example, a resolution of 800x600 means that the screen can
display 800 pixels in a row and can display 600 rows. The more pixels
displayed, the higher the resolution and the clearer the images.
ROM - Read-only memory. Permanent computer memory dedicated to a
particular function. For example, the instructions for starting the computer
when you first turn on power are contained in ROM. You cannot write to
ROM.
