This is something that has bothered me for a while. When you open your active Network Connection in Windows (Pre-Vista) and display the Status dialog, it will show you the IP, hours online etc and below the "nice" animation there is a display of either Transmitted and Received Bytes or Transmitted and Received Packets.
What determines which it chooses? Is it the network driver? Is it random? :)
Please enlighten me. :)
