Direct Client to Client Protocol
<networking> (DCC) An {IRC} {protocol} created to allow users
to chat privately and to send and receive files directly
instead of having to go thorugh the IRC servers. DCC protects
users from being monitored by IRC Server operators that have
enabled conversation logging. It also allows much more
efficient use of available {bandwidth} as the data does not
need to be {broadcast} all over the world just to reach a
specific user.
The available DCC commands include DCC CHAT (direct user to
user chat), DCC SEND (direct user to user file send) and DCC
GET (file acknowledgement from a receiver).
