IRC has different channels and each channel contains a separate conversation. Every IRC is owned and maintained by a channel operator who has complete control over the channel, including making the channel private, removing users, shutting down the channel. The channel operator is the person who originally opened a new channel. This is a simple one-line command which anyone can do that creates a log of the discussion or lecture in your home directory. When using IRC, an Internet user will type a message that will then instantly appear on other IRC users' computer screens.
People generally type one sentence at a time back and forth to each other.
Click the icon for your IRC program and then enter an address of an Internet site that carries IRC channels. Probably the best way to use IRC for education is to establish your own channel and then set a date and time for your specific conversation. This should help keep inappropriate materials out.
