There are many different classes of data that can be sent across a network. Depending on the volume of
traffic on the network and the capacity of the equipment in the network, data can be delayed, or lost and
retransmitted before reaching its destination. Normally this is not a problem since the data is reassembled at
the destination. If the data consists of text or numeric data to be stored on the destination computer, the user
would not notice the delay. But if the data was voice, streaming video, or other delay sensitive data, delays
would be undesirable. Video sequences would be jerky and voice communication would have annoying
gaps.
