Re: Y3K
Hi Anil, I regularly achieve speeds in excess of 150kbits/sec (or is it K, oh well) dowloading plain text log files from my website over a "56k" modem. This is possible because most modern modems do compression which works very well on text files and bmp impages, and not very well on jpeg images since they are already compressed.

Indeed, I can see how they can consider this conversion to be extremely complicated, requiring a supercomputer and several rocket scientists on staff. I hear that the conversion program ran for several years, costing millions, and finally came up with the long-awaited answer: 42. Of course, those of us that don't have this kind of funding, have to do the conversion long hand. As complicated as it may seem, it actually can be done, by applying the complex formula: 1 CPS = 1 Hz Egon :-) "Beam me up Scotty. There is no intelligent life on this planet." __ Egon H.

Had the indication been kB/sec, that would have made the connection between kByte and kbit much more obvious. But that was not to be...

Re: Y3K
Hans and Dan: You're overlooking the fact that by definition in modern computers a byte = 8 bits so when they say 100Mb drive they mean exactly that, 100 megabytes = 800 megabits capacity. ( if you ignore the parity bit which is seldom transmitted or recorded.). . A 56K modem downloads files at 5Kbytes/sec = approx. 40kbps with the usual line loading.

RE: Y3K
I dont think this is right. There are times when my modem says data is being transferred at 10k/s. So does that mean actual throughput is 10x8 = 80kbps from a 56kbps modem ?? Data transfer over an analog line would essentially depend on your line and the distance from CO (besides your system). Remember, a 56kpbs modem is not promising data transfer at 56kbps; what the modem does do is PROCESS information (you know..modulation...demodulation) at 56kbps. So for the same data transfer of 4k/s a 56k modem would appear to be "faster" than a 28.8k modem. It is smart; it understands faster :-) To transfer data at speeds higher than 10k/s you need to "Push" and "pull" the information over an analog line. Standard modems can't do that. But DSL modems can.
