    i don't remember that i mentioned before but i have dsl modem
    and have 256 kbps connection with it

    while i download a file from a server generally it is transferred
    with 27 kbits

    questions are coming

    1- devices : pc ,modem and other modem or a router in telecom

    does 256 kbps tell me that there is a cable with 256 kbps between my modem and the one
    in telecom ?


    if not how can this be explained?

    for ex. i use cat5 eth.cable between my modem and
    pc that has 100 Mbps so "since there is a cable the cable gives me the speed".



    2- Is 27 kbit speed for the server or my pc ?

    256k is the maximum bandwidth speed and if I understand your question right the 27mbps is your maximum download from your server.

    max.bandwidth speed means

    at a time max. 256 kbps data will be transferred ?

    BUT SHOULDN'T A CABLE EXIST BETWEEN MY MODEM
    AND TELECOM FOR THIS ?


    BECAUSE FOR EX. BETWEEN MY MODEM AND PC
    THERE IS A CABLE "FOR MENTIONING A BANDWIDTH "

    No - it means that the speed has been set on the DSLAM at the telephone exchange by your ISP. It *might* be that that is all your phone line is capable of, but it *might* otherwise be that that is all you are prepared to pay for.

    No - it isn't just the cable that sets the speed. In this case good cat5 can do higher than 100Mbps. The figure of 100Mbps is set by your ethernet adaptors on your PC and in the ADSL modem.

    The 27 figure is almost certainly not kbits, but will be 27kBytes. This corresponds with the line speed set for your line.

    There is no requirement that all the cables connecting your PC to some remote device must have the same speed.

    In the case of the Internet these links can have any speed between 56kbits to 1Gbit or higher.

    Its the good old bits and bytes thing again.
    256 kbps is 256 kilo bits per second
    27 Kb is 27 kilo bytes.
    1 byte is 8 bits, so 256 would give about 32 KBytes, but there is some overhead in the transportheaders, so 27 is a normal score.

    Sorry to post this but

    shouldn't it be KBps for "27 Kb is 27 kilo bytes" cause am sure the K and k means something else

    yes it is called with kilobytes...

    but still doesn't understand the eth.cable event

    I THINK IF WE TELL ABOUT " SPEED OR BANDWIDTH"
    THERE HAS TO BE A CABLE OVER THERE"

    to try and answer your questions

    1- devices : pc ,modem and other modem or a router in telecom

    does 256 kbps tell me that there is a cable with 256 kbps between my modem and the one
    in telecom ?

    A)No, this is the service that your ISP (Internet Service Provider) is supplying you with

    if not how can this be explained?

    A) There could be any amount of reason as to why your on a 256kbps service Price, Range from Exchange, Type of wiring used Copper or Aluminium, and am sure there is an issue aswell if your line has been paired(although dont quote me on that one)

    for ex. i use cat5 eth.cable between my modem and
    pc that has 100 Mbps so "since there is a cable the cable gives me the speed".

    A) hbroomhall explained this already


    2- Is 27 kbit speed for the server or my pc ?

    A) Your bottleneck is your Internet Connection

    Er - do you want to reword that question so it makes sense please? :biggrin

    Your ethernet connection between the PC and the modem is running at 100Mbps because the two ends negociated that speed.

    That doesn't mean that it will be filling it up with data. As your next link in the chain is 'only' 256kbps then the ethernet segment will be barely used!

    kobem,

    could do us all a favour and post in 1 colour please. Just looking at your rainbow post is straining my eyes and giving me a headache.

    If you're feeding a firehose with a drinking straw, the amount of water will be that of the straw.
