    Well, a discussion with a friend left us with the following: 1 Kb = 1024 bytes, fine everyone knows that but 1 Mb = 1024*1000 or 1024*1024 ??? A search on the internet didnt help much, both numbers are used. Windows Explorer (under XP) uses 1024*1024. Which one do you favor? After all, Mega stands for 1000, Giga for 1000*1000 and so on. Or am I wrong about this? Vote against software patents in europe

    I believe it goes like this: B - byte b - bit K or k when next to B means 1024 bytes (2^10) and when next to b means 1000 bits (10^3). M when next to B means 1024*1024 bytes (2^20) and when next to b means 10^6 bits. G when next to B means 2^30 bytes and when next to b means 10^9 bits respecitvely. Best regards, Alexandru Savescu

            That is very well explained. :-) Now can you explain to the audience when we use superscript and subscript. eg Gb and mB :-) Regardz Colin J Davies

              Actually, it's 56000/10 = 5.6KB per second. You forgot the start and stop bits for each byte.

                That's a small m there, so you must mean milliBytes.

                      Well...I thought that a small 'k' was used for 'kilo'? I'm not too sure of that part, though. And I know that capital M, G, and T are used for mega etc.

                          According to the official standard the binary prefixes should be distinguished from the decimal ones with an "i" in the middle: 1 MiB = 2^10 B, 1 MB = 10^6 B etc.

                            Actually you're both wrong, if you live in the US. The FCC won't let modem's go over a certain rate, I think its 42000 or 46000 ;P James Simplicity Rules!

                                A 25-year old Federal Communications Commission rule limits speeds to 53,000 bps by restricting the electrical power of modems used by Internet service providers to connect to the phone network.
