Mathematics For Computer Science - Binary Prefixes

​Binary prefixes
Different quantities of bits can be described with specific names and prefixes. You should
know quite a few of these terms, but you also need to know what they represent.
■ At the very basic level you have bits, nibbles and bytes.
■ A bit is just 1 binary digit, e.g. 1 or 0.
■ A nibble is 4 bits, e.g. 0110 or 1101.
■ A byte is 8 bits (or 2 nibbles), e.g. 10101101 or 01011011.After a byte you start recording the number of bits in powers of 10.

The binary prefix for 2¹⁰ is Ki and it is called kibi.

the binary prefix for 2²⁰ is Mi and stand for Mebi

The binary prefix for 2³⁰ is Gi and stand for Gibi

The binary prefix for 2⁴⁰is Ti and stand for Tebi

​These are called prefixes because they will all come before what they represent, which is
the number of bytes:

kibibytes= 2¹⁰ =1024 bytes

mebibytes= 2²⁰=1048576 bytes

gigibytes=2³⁰=1073741824 bytes

tebibytes=2⁴⁰=1099511627766 bytes
