Explaining the VNC protocol

Shared by on Mar 09, 2022

Virtual Network Computing (VNC) is a remote control protocol that allows a user to remotely control a computer or access its desktop over a network connection. The VNC protocol is based on the Remote Framebuffer (RFB) protocol, which was developed as a way to remotely access Windows, macOS and and Linux systems.

The VNC protocol works by transmitting updates to the screen of the remote computer over the network connection to the VNC client, which displays the updates on the local screen. The VNC client also sends input events, such as keyboard and mouse clicks, back to the VNC server, which processes the input and updates the screen of the remote computer accordingly.

VNC is a widely-used protocol that is supported by a range of client and server software applications, including open-source and commercial options. It is often used as a way to remotely access and control a computer from a different location, such as when providing technical support or accessing a work computer from home.
