How many total unique bit patterns can be encoded using an 8-bit byte?
Answer and explanation
Correct answer: A. 256
- Step 1: Use binary combinatorics for bits: Total states .
- Step 2: For bits: distinct unique binary representations (ranging from 0 to 255 unsigned).
Answer
256.
Why not the others: 128 corresponds to addresses; 512 corresponds to addresses; 64 corresponds to addressable memory locations.
