It's a pretty neat trick, honestly.

How VNC Works Its Magic

At its core, VNC works with two main parts: a server and a viewer (or client). The VNC server runs on the computer you want to control remotely, in our case, the Raspberry Pi. This server captures the Pi's screen output and sends it over the network. The VNC viewer, running on your Windows 10 PC, receives these screen updates and displays them. When you move your mouse or type on your keyboard on your Windows PC, the viewer sends those actions back to the Pi's VNC server, which then applies them to the Pi's desktop. It's, like, a seamless back-and-forth communication.

This whole process happens, you know, pretty quickly over a local network, giving you a responsive experience. For example, you could be sitting in your living room, using your laptop, and controlling a Raspberry Pi that’s in your garage, all without breaking a sweat. It’s a very practical way to manage multiple devices from one spot.

Why Choose a Free VNC Viewer?

There are commercial VNC solutions out there, but for most hobbyists and even many small businesses using Raspberry Pis for IoT, a free VNC viewer does everything you need.
