Which of the following statements is/are correct? Choose the correct answer from the options given below:
1.It is usually faster to access data stored in RAM than that on a hard drive
2.The hexadecimal number 99 is the same as the decimal number 99
A1 only ✓ Correct
B2 only
CBoth 1 and 2
DNeither 1 nor 2
Correct answer: (A) 1 only
Explanation
Only the first statement is correct, that accessing data in RAM is usually faster than accessing it on a hard drive.
Statement 1 is true because RAM is electronic with no moving parts, while a hard drive relies on spinning platters.
Statement 2 is false, because the hexadecimal number 99 does not equal the decimal number 99.
Hexadecimal 99 means nine sixteens plus nine, which is 153 in decimal.
Only when a hex value uses digits 0 to 9 in a single place does it match the same decimal digit.
Hexadecimal is base sixteen, so each place is worth sixteen times the one to its right.
