The 8-bit binary value 1100 0101 corresponds to how many bytes of data?

Difficulty: Easy

Correct Answer: 1

Explanation:

Introduction / Context:Computer memory and data movement are measured in bits and bytes. Knowing how many bits form a byte is fundamental for understanding storage sizes, data alignment, and instruction encoding. Here we translate an 8-bit sequence into the number of bytes it represents.

Given Data / Assumptions:

  • Binary sequence: 1100 0101 (8 bits shown, grouped 4+4 for readability).
  • Definition: 1 byte = 8 bits.
  • No parity, start/stop, or framing bits are implied.

Concept / Approach:

  • Count the number of bits in the sequence.
  • Divide by 8 to obtain the number of bytes.

Step-by-Step Solution:

Count bits: '1100 0101' contains 8 bits.Apply definition: 8 bits = 1 byte.Therefore, the sequence occupies exactly 1 byte.

Verification / Alternative check:

Any 8-bit pattern—from 0000 0000 to 1111 1111—constitutes 1 byte; 1100 0101 is one such pattern.

Why Other Options Are Wrong:

  • 2, 4, 8 bytes: Would correspond to 16, 32, 64 bits respectively, which are not shown.
  • None of the above: Incorrect because 1 is exactly correct.

Common Pitfalls:

  • Confusing nibble (4 bits) with byte (8 bits).
  • Assuming whitespace in grouped bits adds extra bits—spacing is for readability only.
