PuTTY is a free and open-source software that enables secure remote connections over various network protocols, such as Secure Shell (SSH), Telnet, and Raw Socket connections. The primary function of PuTTY is to act as a terminal emulator for these protocols, allowing users to access and manage remote systems as if they were directly interacting with them.
