Byte: A unit of digital information consisting of 8 bits, the basic unit used to measure computer storage and memory.
Explanation
A bit is the smallest unit of data (0 or 1), and a byte contains 8 bits. Larger units include kilobyte (KB) = 1000 bytes, megabyte (MB) = 1000 KB, gigabyte (GB) = 1000 MB, and terabyte (TB) = 1000 GB. File sizes are measured in bytes; for example, a text file might be 50 KB while a movie might be 4 GB. Computer memory and storage capacity are measured in bytes. Understanding bytes helps determine file sizes and storage needs. A typical smartphone has 64 or 128 GB of storage, meaning it can store that many bytes of data.
Example
One character of text takes up 1 byte. A 3-minute song takes about 3-5 MB. A HD movie takes about 4 GB.
