One byte equals how many bits?

Understanding fundamental computer architecture is key here. A bit (binary digit) is the smallest unit of data in a computer, representing a 0 or 1. A byte is a standard unit of digital information that consists of eight bits. This 8-bit structure allows a byte to represent 256 (28) distinct values, making it a practical unit for encoding characters and small numbers.

• Option A (8) is correct because it is the universally accepted definition of a byte in computing.
• Options B (10), C (12), and D (16) are incorrect. While larger data units like "words" can be 16, 32, or 64 bits depending on the architecture, a byte specifically refers to 8 bits. These distractors do not represent the standard definition of a byte.
