Explanation
11)once socket is constructed the following wcode that will send
our UDP message
sendto(Message, (UDP_IP_ADDRESS, UDP_PORT_NO))
according to this format
only option a will fit
newMsg.encode(), CAddr is the correct one
--
13)in P2P architecture there is minimal or no reliance on dedicated
servers
because, each and every computer can act both client and
server
--
14) HTTP request messages are in ASCII format
--
15)
CNAME means Canonical Name
