Blimey, mate, that's one helluva bump
Well, it gives the background of how commands from the TCP/IP protocol actually work. Most people know they can ping a device to see if it's on the network, without really understanding why ping is so useful at doing what it does. I didn't really learn the ins-and-outs of TCP/IP until years after I'd been using some of the commands, but it does help to have that underlying knowledge as well.
If this sort of thing interests anyone, then I can recommend reading the TCP/IP Guide by Charles M. Kozierok -
