# 1 Kilobyte equals how many bytes

Electrical Engineering XYZ MCQs

1 Kilobyte equals how many bytes:

1. 1012 bytes
2. 1000 bytes
3. 1008 bytes
4. 1024 bytes

Correct answer: 4. 1024 bytes

Explanation:

• A kilobyte (KB) is a unit of digital information storage equal to 1024 bytes.
• This is because computers typically use binary (base-2) rather than decimal (base-10) numbering systems. In binary, 2^10 (1024) equals 1 kilobyte.
• It’s important to note that in the International System of Units (SI), the prefix “kilo-” typically means 1000. However, in computing, kilobyte traditionally refers to 1024 bytes, and this convention has been widely adopted.
• So, while the SI standard defines a kilobyte as 1000 bytes, in computing contexts, it’s commonly understood to be 1024 bytes. However, due to some standardization efforts and potential confusion, you might sometimes see the term “kibibyte” (KiB) used to refer specifically to 1024 bytes, while “kilobyte” might strictly adhere to the SI standard of 1000 bytes.
