  • Terminology● Network● Client● Channel● Operator● Channel Operator● Commands
  • Network● Consists of at least one server, but can consist of many servers in a spanning tree.● What your client connects to so that you can chat with others.● Each server in the tree is running IRC daemon software.● In a multi-server network, two users dont have to be on the same server to chat with one another.
  • Client● Anything that connects to an IRC network that isnt a server.● Includes your chat program and bots as well.● Each client must be uniquely identified.● Messages to clients are transmitted through the server (no need for direct connection).
  • Channel● A "room" that users can join and chat as a group.● Messages sent to a channel are seen by all who have currently joined that channel.● Channel names are unique and usually prefixed with hash character (#).● Channels are created when the first user joins the channel and destroyed when the last user leaves.
  • Operator● A client with special privileges on a network.● Help maintain the network by adding and removing servers; adding, removing and banning (if necessary) other clients, etc.
  • Channel Operator● A client with special privileges on a channel.● Help maintain the channel by removing disruptive clients, setting the topic and changing channel settings (like keywords).● If you are the first to join a channel, you are often made its operator automatically.
  • Commands● Commands are how clients interact with servers.● Prefixed with a forward-slash (/).● They often take one or more arguments.● On most networks you can issue the help command for more info about any command ○ /help ○ /help <command>● Can usually run commands for one channel while in another by specifying other channel.
