PuTTY FAQ. „[PuTTY is] the name of a popular SSH and Telnet client. Any other meaning is in the eye of the beholder. It's been rumoured that ‘PuTTY’ is the antonym of ‘getty’, or that it's the stuff that makes your Windows useful, or that it's a kind of plutonium Teletype. We couldn't possibly comment on such allegations.” though "tty" is the name for a terminal in the Unix tradition, usually held to be short for Teletype, and putty is material for sealing glass in window frames, and may refer to Microsoft Windows lacking a built in SSH client.[forrás?]
