    A PC is downloading a large file from a server. The TCP window is 1000 bytes. The

    server is sending the file using 100-byte segments. How many segments will the

    server send before it requires an acnowledgment from the PC!

    10 segments"

    #

    A host device needs to send a large video file across the networ while $roviding

    data communication to other users. %hich feature will allow different

    communication streams to occur at the same time& without having a single data

    stream using all available bandwidth!

    multi$le'ing "

    (A technician wishes to use T)TP to transfer a large file from a file server to a

    remote router. %hich statement is correct about this scenario!

    The file is segmented and then reassembled in the correct order at the destination&

    if necessary& by the u$$er-layer $rotocol."
