Computer Science for IGCSE & O level - Data Representation (Section 2 - No. 42)
What is the maximum number of values that can be represented using a single byte (8 bits)?
8
255
256
1024
توضیح
A byte has 8 bits. Each bit can be 0 or 1 (2 options). 2^8 = 256. Since we start at 0, we can represent 256 unique values.
