What is a byte?
a) A group of 8 bits
b) A type of storage device
c) A unit of time
d) A type of file format
Answer:
a) A group of 8 bits
Explanation:
A byte is a group of 8 bits. It is the standard unit of data used to represent information in a computer. Since a bit can hold one of two values (0 or 1), a byte can hold 256 different values, from 0 to 255, which can represent a character, a small number, or part of an image.
Bytes are the building blocks of data in computing. For example, a file size is often measured in kilobytes (KB), megabytes (MB), or gigabytes (GB), which are multiples of bytes.
The byte is important because most computer architectures are byte-addressable, meaning the smallest addressable unit of memory is a byte. Understanding the concept of a byte is essential for working with data in programming and computing systems.
