RaspberryPi Basics: Part V- Setting up VNC!

WIKI says Virtual Network Computing  is a graphical desktop sharing system that uses the RFB protocol (remote framebuffer) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.  VNC is platform-independent – a VNC viewer on one operating system may connect to a VNC server on the same or any […]
