man write
man talk
man wall
========
Write does just that. Writes what you type (ending the message with a "Ctrl-D") to the terminal of the user you want to send a message to. It is one-way.

Talk will try to connect to a users terminal to start a two-way conversation. It uses the curses library to control the screens (terminals) used in the connection.

wall is "write to all" one way communication to all logged in users. It is how the "shutdown message" is sent when root uses shutdown (1m) to change the run level of a system.

The "man" pages (UNIX Manual) contain about 80% of the information needed to understand how to use the basic commands that come with the system.
