So you can work on the Unix machine as if you were sitting at its console, while actually sitting somewhere else.There may be a small delay between opening the app and seeing this dialog. Then, anything you type into that window is sent straight to the Unix machine, and everything the Unix machine sends back is displayed in the window. In really simple terms: you run PuTTY on a Windows machine, and tell it to connect to (for example) a Unix machine.

PuTTY implements the client end of that session: the end at which the session is displayed, rather than the end at which it runs. These protocols are all used to run a remote session on a computer, over a network. PuTTY is a client-side terminal emulator software for the SSH network protocol.
