I have a 256 kbps DSL line, but I cannot download faster than 32 kB/s, why is that?
There is a big difference between kbps – kilo-bits-per-second – and kB/s – kilo-Bytes-per-second. In the computer jargon, bits and bytes are both units used to measure file sizes, but 1 byte = 8 bits. Therefore, your DSL speed, which is 256 kbps (kilobits per second), is also 256 / 8 = 32 kB/s (kilo Bytes per second). Most of the time, your computer displays download speeds in kB/s, not kbps. So, if you are downloading a file at 32 kB/s, you making full use of your 256 kbps DSL line.
