byte

A byte is a basic unit of digital information used to store data in computers. It typically consists of 8 bits, where a bit is the smallest piece of data, representing a 0 or 1. Bytes are used to measure the size of files and memory, with larger data quantities expressed in kilobytes (KB), megabytes (MB), or gigabytes (GB). For example, a single letter or number usually takes one byte, while more complex files like images or videos require thousands or millions of bytes. Essentially, bytes are the building blocks that help computers process, store, and transmit digital information efficiently.
