Consider the following design of an IP$-$based Internet chat system that permits multiple users to converse using single$-$line text messages:

A chat monitor resides at a well$-$known network address, uses UDP to communicate with chat clients, sets up chat servers for each chat session $($a chat room$),$ and maintains a chat session directory.

A chat server uses TCP for communication with clients.

A chat client allows users to list all chat sessions, and to start, join, and leave any chat session.

With reference to one or more diagrams, present, using pseudo$-$code with a syntax similar to either Java or C$,$ your design of the Internet chat system.

In your pseudo$-$code, use uppercase letters to highlight all calls to functions provided by the Berkeley sockets API.
