Conversion:
Ratios de Transferencia y ancho de banda
1 byte es igual a 8 bits
Byte = the well-established information measure unity
1 byte = 8 bits and 1
kilobyte (K / Kb) = 210 bytes = 1,024
bytes
1 megabyte (M / MB) = 220
= 1,048,576 bytes
and 1 gigabyte (G / GB) = 230
bytes = 1,073,741,824 bytes
1 terabyte (T / TB) = 240
bytes = 1,099,511,627,776 bytes and 1 petabyte (P / PB) = 250
bytes = 1,125,899,906,842,624 bytes
1 exabyte (E / EB) = 260
bytes = 1,152,921,504,606,846,976 bytes
bit = the well-established data transfer unity
1 kilobit = 1000 bits
1 megabit = 1000000 bits
Datas of the hard disk are counted
in kilobytes, however the transfer data rates are in
kilobits.
Fait: A 56k
modem (= 56000 bits) needs for transferring of 56k datas (= 458753 bits)
not 1 second, but at least 8,2 seconds.
This is confusing and you must always bear it in mind, when calculating
transfer rates.
