Amar KHELIFI, 1kbits does not = 1024bits and 32kbps does not = 32768bps. 1kbps = 1,000bps & 32kbps = 32000bps. "k" simply means 1,000. The whole idea of 1KB (KiloByte) = 1024 bits has to do with binary math and the fact that computers deal in bytes vs. bits. 2^10 = 1024, which is divisibly by 8 (whereas 1,000 would not be). It would be very inconvenient for a computer to have to deal with information blocks that are not divisible by 8. Modern communications systems are not byte-aligned at all and deal strictly in bits. For example, a DS0 is 64kbps. That's 64,000bps. As a side note, and I'm not sure that there's any official convention to go along with this, in general, a KiloByte is abbreviated KB, with a capital K. kilobits per second is generally abbreviated kbps, with a lower-case k. Thus, when you see a capital K, it's safe to assume 1024 is being implied, whereas when you see a lower-case k, it's safe to assume 1,000 is being implied.
