Diplay resolution is measured in:
-
Mb
-

-
Pixels
-
Inches
-
Microns
Correct Answer(s)
A. Pixels
A. MicronsExplanation
Display resolution refers to the number of pixels that can be displayed on a screen. Pixels are the smallest units of an image, and the more pixels there are, the higher the resolution and the sharper the image. Microns, on the other hand, are a unit of measurement used to measure the size of objects, typically at a microscopic level. While microns can be used to measure the size of individual pixels, display resolution is generally not measured in microns but rather in the number of pixels. Therefore, the correct answers for measuring display resolution are pixels.Rate this question:

-
01001
Correct Answer
A. 01001Explanation
The correct way to represent the number 9 in binary is 01001. In binary representation, each digit represents a power of 2 starting from the rightmost digit. The rightmost digit is 1, representing 2^0, and the second rightmost digit is 0, representing 2^1. The third rightmost digit is 0, representing 2^2. The fourth rightmost digit is 1, representing 2^3. Finally, the leftmost digit is 0, representing 2^4. Adding the values of the digits that are 1, we get 2^0 + 2^3 = 1 + 8 = 9.Rate this question:

Correct Answer
A. 11110Explanation
The correct way to represent the number 30 in binary is 11110. In binary representation, each digit can have a value of either 0 or 1. Starting from the rightmost digit, each subsequent digit represents a power of 2. Adding up the values of each digit gives the decimal equivalent. In this case, the binary number 11110 translates to (1 * 2^4) + (1 * 2^3) + (1 * 2^2) + (1 * 2^1) + (0 * 2^0) = 30.Rate this question:
