What are bits, bytes, and other units of measure for digital information?


  The bit is a basic unit of information in computing and digital communications. A "bit" is the smallest unit of storage in measuring digital information. A bit stores only 0 or 1. In a computer, everything is stored in bits.

  8 bits together make a byte. Similarly, 1024 bytes make a kilobyte (KB). Here are the further units of measurements for digital information.

1 byte 8 bits
1 kilobyte (KB) 1,024 bytes
1 megabyte (MB) 1,024 KB
1 gigabyte (GB) 1,024 MB
1 terabyte (TB) 1,024 GB
1 petabyte (PB) 1,024 TB

  Other units include exabyte (EB), zettabyte (ZB), yottabyte (YB), etc.
