What are the differences between hyper-terminal and putty?

HyperTerminal is a terminal emulation program that was included with Windows operating systems up to Windows XP, primarily used for serial communication. It lacks many modern features and updates, making it less versatile for current applications. In contrast, PuTTY is a free and open-source terminal emulator that supports various network protocols, including SSH, Telnet, and SFTP, and is widely used for remote access to servers. PuTTY offers more features, better security options, and greater flexibility, making it a preferred choice for many users today.
