What are the initial two commands an IRC client sends to join an IRC network?

Explanation:
When an IRC client connects, it first registers with the server by exchanging the basic identification commands. The USER command supplies the user’s identity (username, host, server, and real name), and the NICK command then assigns the nickname that will be used in chats. This pair establishes who you are on the network and is required before you can do anything else. The PASS command would only come into play if the server requires a password for registration, in which case it would be sent before USER. The JOIN command comes later—after registration—to enter channels. So the initial two commands are USER followed by NICK.
