BIT   -  A single character of a language, having just two characters - either of the binary digits O or I

NIBBLE    -  This is not a common term.  It is a group of 4 bits and 2 Nibbles will equal 1 Byte

  • A combination of 8 binary digits.  Each byte represents a single character or letter.
  • The capital letter A = 01000001
  • The space occupied by a single character in a computer store

KILOBYTE   ..............  KB
  • One kilobyte is 1,024 bytes or characters
  • Approximately equal to one A4 page of double-spaced text

MEGABYTE   ............  MB
  • One megabyte is 1.024 KB
  • Approximately equal to one reasonably sized book

GIGABYTE ................  GB
  • One gigabyte is 1,024 MB
  • Approximately equal to a shelf of books in a library
