Technical note: These terms are those used most commonly and is the binary
system, and you can be comfortable using it. The binary
system is a base 2 system in which a bit is a binary digit, either
a 1 or a 0, and a byte equals 8 bits. There is also a decimal (or "denary")
system, in which a kilobyte = 1,000 bytes instead of 1024 bytes, and they say it
is a kibibyte that equals 1024 bytes. They also use the terms gibibytes (GiB),
Mebibytes (MiB), and Tebibytes (TiB). This is the system of the
International System of Units (SI). The binary system is a base 2 system used
by operating system makers such as Microsoft and Apple and also is used on CDROMs
and flash drives; the decimal system is a base 10 system, used by makers of
hard drives and DVDs. There also is an octal number system (base 8) and a
hexadecimal system which is a base 16 system. The latter two are used by computer
programmers, and are popular because they make it convenient to abbreviate binary
numbers which can get to be quite long.
