PuTTY – Most popular terminal emulator

PuTTY is a free serial console, terminal emulator and the most popular SSH client. Written in C language and developed by Simon Tatham, PuTTY supports several network protocols such as Telnet, Secure copy protocol (SCP) rlogin, and SSH. It is one of the oldest terminal emulators that are still actively developed and updated.

Although initially developed for Windows OS, it is now ported to many operating systems. It does not support session tabs; several wrappers provide that function. Commonly, PuTTY is leveraged to connect routers and switches using SSH.
