Two different number systems are used in computer specifications:
a The decimal system which consists of ten digits from 0 to 9, is used for measuring speed.
b The binary system, which only has two digits (1 and 0), is used for measuring capacity.
The following prefixes are also used in measurements:
| Decimal system | Binary system | |
| kilo | 103 = 1 thousand | 210 = 1,024 |
| mega | 106 = 1 million | 220 = 1,048,576 |
| giga | 109 = 1 thousand million | 230 = 1,073,741,824 |
e.g. 1.7 GHz = one point seven thousand million cycles per second
256 MB = 256 x 220 bytes = approximately two hundred and fifty six million bytes
Communication is provided between applications programs (word processors, drawing programs, etc.) and the computer hardware (the physical components of a computer system) by a set of programs collectively known as the operating system e.g. Microsoft Windows, MacOS.
