W1002-Annex-3 PuTTY

From Coder Merlin


PuTTY is an SSH and telnet client that runs on Windows, Linux and UNIX. This terminal emulator establishes a TCP/IP connection and works with multiple network protocols.

Helpful Hint
Did you know that the TTY in PuTTY is a UNIX terminal command that prints the name of the terminal you're connected to? It's derived from the word TeleTYpewriter.
