The good cholesterol, HDL, delivers cholesterol to the adrenals and ovaries for hormone production and takes up excess cholesterol for processing and disposal in the liver. Triglycerides, the smallest particles, are incorporated into both HDL and LDL.
Internet Relay Chat (IRC) is an application layer protocol that facilitates communication in the form of text. The chat process works on a client/server networking model. IRC clients are computer programs that a user can install on their system.
The first IRC server software that allowed chatters to connect to it was the original IRCd developed by Jarkko Oikarinen, the inventor of the IRC protocol. Inspired by several Bulletin Board System chat programs, he wanted to do some more powerful realtime chat on his own and consequently invented the now well-known chat protocol.
