to the left edge of the screen horizontally is called the
Horizontal Cycle and the inverse number of the Hor-
izontal Cycle is called the Horizontal Frequency.

same image many times per second to display an
image to the user. The frequency of this repetition is
called the Vertical Frequency or Refresh Rate. Unit:
