    • RFB stands for Remote Frame Buffer.

    • It works at the frame buffer level, so it can work with any windowing system.

    VNC - Basics

    VNC(Virtual Network Computing) helps you to access the remote desktop. It makes the remote access simpler and easier by way of transferring the frame buffer updates across the network. So, It gives the feel like sitting in front of a remote machine and accessing it.

    It is a proven model of accessing the remote desktops. The great thing about VNC is, it's platform independent. So, it is possible to take control of a windows machine from Linux/Mac/Cent or any.,
