Binary Data Units: Bit, Nibble, Byte, Megabyte, and Gigabyte, Quizzes of Computer Science

Definitions for various binary data units, including bit, nibble, byte, megabyte, and gigabyte. A bit is the basic unit of information, represented as a 0 or 1 in binary notation. A nibble is a group of four bits, and a byte is a group of eight bits. Megabytes and gigabytes are larger units of measurement, with one megabyte equal to 220 bytes or approximately one million bytes, and one gigabyte equal to one billion or 230 bytes.
