KHz, MHz, GHz
- B.
KVs, MVs, GVs
- C.
KAs, MAs, GAs
- D.
None of above
Correct Answer
A. KHz, MHz, GHzExplanation
Clock frequency is a measure of how fast a computer's clock is ticking, indicating the number of cycles it can complete in a second. It is typically measured in kilohertz (KHz), megahertz (MHz), or gigahertz (GHz). These units represent thousands, millions, and billions of cycles per second, respectively. The options "KVs, MVs, GVs" and "KAs, MAs, GAs" are not standard units for measuring clock frequency. Therefore, the correct answer is KHz, MHz, GHz.Rate this question:

- B.
1001101
- C.
1001011
- D.
1010111
Correct Answer
C. 1001011Explanation
To convert a decimal number to binary, we repeatedly divide the decimal number by 2 and note down the remainder. We continue this process until the quotient becomes zero. Then, we write down the remainders in reverse order to obtain the binary equivalent. In this case, when we convert 75 to binary, we get the binary number 1001011.Rate this question:

- D.
218
Correct Answer
A. 214Explanation
To convert a binary number to decimal, we multiply each digit by the corresponding power of 2 and then sum them up. In this case, starting from the right, the first digit 0 (2^0) contributes 0 to the sum. The second digit 1 (2^1) contributes 2 to the sum. The third digit 1 (2^2) contributes 4 to the sum. The fourth digit 0 (2^3) contributes 0 to the sum. The fifth digit 1 (2^4) contributes 16 to the sum. The sixth digit 0 (2^5) contributes 0 to the sum. The seventh digit 1 (2^6) contributes 64 to the sum. The eighth digit 1 (2^7) contributes 128 to the sum. Adding all these contributions, we get 214. Therefore, the correct answer is 214.Rate this question:
