What does a byte typically consist of?

A byte typically consists of 8 bits. This standard definition allows for the representation of 256 different values (2^8), which is essential for encoding characters in many computing systems, such as ASCII. By using 8 bits, a byte can efficiently store a wide range of data types, including numerical values and individual characters. This structure forms the fundamental building block for data processing and storage in computers and digital systems, making it indispensable in computer architecture and programming.
