Secure Shell (SSH) is a function that allows users to remotely access and control a Raspberry Pi command line.

If you need to access your Raspberry PI projects without using a monitor, you can set up a Secure Shell (SSH) on your computer.

Then, to SSH into your Pi from a Windows machine, I recommend a third-party tool called PuTTY. It's a free, open-source program built for exactly this purpose.

Once you note down the IP address, download PuTTY. This is a free SSH client for remotely accessing the Raspberry Pi. Logging into the Pi with PuTTY is easy.
