One kilobyte is equal to approximately ____ memory locations.
A
1, 000
B
10, 000
C
100, 000
D
1, 000, 000
Explanation: 

Detailed explanation-1: -One kilobyte (K or KB) equals approximately 1, 000 memory locations and one megabyte (M or MB) equals approximately one million locations A memory location, or byte, usually stores one character.

Detailed explanation-2: -Originally, a byte was considered a collection of 8 bits, the smallest number of bits that were able to express a number, letter or character within binary. A kilobyte is approximately 1, 000 bytes (specifically, 2 to the 10th power or, in decimal form, 1, 024 bytes).

Detailed explanation-3: -A kilobyte (KB) is 1, 024 bytes, not one thousand bytes as might be expected, because computers use binary (base two) math, instead of a decimal (base ten) system. Computer storage and memory is often measured in megabytes (MB) and gigabytes (GB).

Detailed explanation-4: -1 KB = 1024 Bytes. 1 MB = 1024 * 1024 Bytes.

Detailed explanation-5: -KB does and has always meant 1024 bytes.
