Question
In a system which has 32 registers, the register id is __________ long.Question 2Select one:a.5 bitb.16 bitc.6 bitd.8 bit
Solution
The answer is c. 6 bit.
Here's the step-by-step explanation:
-
The number of registers in the system is 32.
-
To represent 32 different items, you need a binary number.
-
The binary number system is base 2, so you calculate the number of bits needed by using the formula 2^n, where n is the number of bits.
-
You need to find the smallest 'n' such that 2^n is equal to or greater than 32.
-
2^5 = 32, so 5 bits could represent 32 registers. However, in computer systems, we usually use a number of bits that is a power of 2. The next power of 2 after 5 is 6.
-
Therefore, the register id is 6 bits long.
