How many bits are equal to one byte?

• A. 4 bits
• B. 8 bits
• C. 16 bits
• D. 32 bits

Answer: (B)

A byte is a standard unit of measurement in computing that consists of 8 bits. This is foundational in digital systems, as a bit represents the most basic binary value (either 0 or 1), which is fundamental to how data is stored and processed in computers. The grouping of 8 bits into a byte allows for the representation of a wide variety of information, such as a single character in text.

The choice indicating 8 bits aligns with the widely accepted conventions in computer science and digital electronics, establishing a byte as the minimum addressable unit of memory in most computer architectures. Consequently, this definition is crucial for understanding data sizes, memory storage, and data transmission in the context of computing.
