The rate at which scanning is repeated is called the: A. stroke rate B. refresh rate C. bandwidth D. resolution E. None of the above

The correct answer is: B. refresh rate.

The refresh rate is the number of times per second that a display updates its image. It is measured in Hertz (Hz). A higher refresh rate results in a smoother image, which is especially important for fast-moving content such as video games.

The other options are incorrect for the following reasons:

• Stroke rate is the number of times per minute that a person’s heart beats.
• Bandwidth is the maximum amount of data that can be transmitted over a network connection.
• Resolution is the number of pixels that make up an image.
• None of the above is a measure of the rate at which scanning is repeated.
