 Bit= from a shortening of the words “ bi nary digit”  The basic unit ofinformation for computers  1 or 0 are the only values

 Byte = 8 bits  Each keyboard character is stored as a byte  Example A=

 St.Kevin’s high, Goulds, NL 

 1 bit = 0 or 1 (b)  8 bits = 1 byte (B)  1 thousand bytes = kilobyte (KB)  1 million kilobytes = megabyte (MG)  1 billion megabytes = gigabyte (GB)  1 trillion gigabytes = terabyte (TB)

Data size (in bytes)example 10 bytes (B)1 word in english language 2 kilobytes (KB)1 typed page of english words 3 megabytes (MG)1 high-resolution picture 2 gigabytes (MG)20 metres of books on a liabrary shelf 1 terabyte (TB)50,000 trees made into paper and printed
