Hello, I have a question about transfer speeds over the Internet . I have an ISDN connection that displays 128 kbs in the taskbar but in the program kazaa ,the top speed is displayed as between 12.2kbs and 15.1kbs. Could you please tell me why this is so, thanks in advance.
128Kbps (Kilobits/s) is the fixed speed at which data bits flow on your ISDN link.
All measured speeds (whether in Kilobits/s or KiloBytes/s) are an effective data transfer rate, taking into account the facts that - some of the time no data is being sent, because your system is tranmitting acknowledgements back to the host - data is not actually always flowing, due to busyness in the various parts of the web - some of the data being sent is not actual data, but control characters and formatting of the data stream - and some of the bits are not data at all, but check bits for error control.
So the effective transfer rate is always a goodly bit down on the raw bit transmission rate - and variable.
