PuTTY is a free and open source terminal emulator application which can act as a client for the SSH, Telnet, rlogin, and raw TCP computing protocols and as a serial console client. The name "PuTTY" has no definitive meaning,^[1] though "tty" is the name for a terminal in the Unix tradition, usually held to be short for Teletype.
PuTTY was written and is maintained primarily by Simon Tatham and is currently beta software.
