One byte is defined as consisting of 8 bits. This standard is universal in computing and digital communications.

To provide some context, a bit is the most basic unit of information in computing, representing a binary state—either a 0 or a 1. When you combine 8 bits, you create a byte, which can represent 256 different values (from 0 to 255 in decimal). This capacity allows for the representation of a wide range of data types, such as a single character in a text (like a letter or a number).

The other options fall short of this standard definition of a byte, with 4 bits representing a nibble, 64 bits typically referring to a specific data size in computer architecture (especially in 64-bit processors), and 16 bits being used for different forms of data representation or in different contexts like encoding (such as in some older systems, often related to half a byte). Thus, the knowledge that a byte equals 8 bits is foundational in computer science and programming.
