[amp_mcq option1=”stroke rate” option2=”refresh rate” option3=”bandwidth” option4=”resolution E. None of the above” correct=”option2″]
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.
