my word, you are a little mixed up. 1MB is 1024KB, not 1048KB, though you got the actual number of bytes correct. But I'm sorry to tell you that communications is indeed measured in base 10 numbers, not base 2. As I stated already, 1Mbps is 1,000,000 bits per second, and 1Kbps is 1,000 bits per second. Most definitely not 1,048,576 bits per second or 1024 bits per second or anything else like that. Yes, computers are binary devices. Yes, they only work with ones and zeroes. Yes, their math is all based off that fact. But communications speeds are all measured with literal thousands and millions, rather than base 2 mathematics, 1024 etc. A 56Kbps modem isn't capable of a maximum of 57344bps, it is capable of a maximum of 56000bps. (Telephone line voltage permitting...) This is well-established fact, not worth debating because there is no debate.
