The Numbers, Please
v A computer memory location can store a byte of
information (8 bits), enough for a keyboard character
v A “normal” whole number (integer) uses 4 bytes
v A machine instruction uses 4 bytes
v Units of memory size are …
o KB, kilobyte, 1024 bytes … just over a thousand bytes, a “K”
o MB, megabyte, 1,048,576 bytes … just over a million bytes,
a “meg”
o GB, gigabyte, 1,073,741,824 bytes … just over a billion
bytes, a “gig”
o TB, terabyte, 1,099,511,627,776 bytes … just over a trillion
