In computer science and industry usage, the prefix ���𲵲�– often does not have its standard scientific meaning of 1,000,000, but refers instead to the power of two closest to 1,000,000, which is 2²⁰, or 1,048,576. The calculation of data storage capacity (measured in bytes) is based on powers of two because of the binary nature of bits (1 byte is 8, or 2³, bits). Thus, a megabyte is 1,048,576 bytes, although it is also used less technically to refer to a million bytes. Other numerical prefixes are interpreted similarly. With data transmission rates (measured in bits per second), a bit is considered as a signal pulse, and calculations are generally based on powers of ten. Thus, a rate of one megabit per second is equal to one million bits per second. However, in certain technical contexts, megabit can also refer to 1,048,576 bits. Similarly, the prefix �쾱����– refers to 1,000 or 2¹⁰ (1,024); ��������– to 1,000,000,000 (one billion) or 2³⁰ (1,073,741,824); and �ٱ����– to 1,000,000,000,000 (one trillion) or 2⁴⁰ (1,099,511,627,776).
