How many bits are there in one byte?

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

Answer: (B)

One byte consists of 8 bits. This standard is foundational in computer science and information technology, where a byte is used as a basic unit of data storage and represents a single character of text in computers. The choice of 8 bits per byte allows for 256 different values (from 0 to 255), which is sufficient to encode standard ASCII characters and many more symbols, enabling effective data representation in software and hardware.

The concept of a byte being 8 bits has become a widely accepted norm in digital systems, thus making it integral to various computing processes. Higher data formats, such as kilobytes, megabytes, and gigabytes, are all based on the byte as a fundamental building block.
