BitTorrent Peer wire protocol (TCP)

Question

How are messages encoded or sent / received by peers?

If there is a message

have: <len=0005><id=4><piece index> 

How is it sent (in binary, how is it converted to binary?) And received?

Is there a specific order in which messages are sent to peers?

I read the spec, but that leaves me with questions.

thank
