Question

the primary partition table for the first partition lists a hexadecimal value of 00 20 03 00 in little endian for the total number of sectors assigned to the partition. what is the decimal equivalent of this hexadecimal number? (hint: use a programmers calculator application, such as windows calculator in programmer mode, to determine the decimal value.)
○ a. 8192
○ b. 8195
○ c. 196,640
○ d. 204,800

Explanation:

Step1: Reverse little-endian hex

Little-endian stores bytes in reverse order, so reverse 00 20 03 00 to get 00 03 20 00.

Step2: Convert hex to decimal

Calculate the decimal value of hex 00032000:
$$0 \times 16^7 + 0 \times 16^6 + 0 \times 16^5 + 3 \times 16^4 + 2 \times 16^3 + 0 \times 16^2 + 0 \times 16^1 + 0 \times 16^0$$
$$= 3 \times 65536 + 2 \times 4096$$
$$= 196608 + 8192 = 204800$$

Answer:

d. 204,800
