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