(I) What is PuTTY?
PuTTY is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet, rlogin, and raw socket connection. PuTTY was originally developed by Simon Tatham for the Windows platform, but it has been ported to various other operating systems. Official ports are available for some Unix-like platforms.

(II) Installation Steps:

b) Following screen would appear once Putty starts.


(1) Enter the host name OR IP address in the “Host Name” field.
