VNC
A graphical remote desktop technology based on the RFB (Remote Framebuffer) protocol, originating in the 1990s. It operates by default on port 5900 and is widely integrated into major operating systems. macOS's Screen Sharing feature is built on this protocol.

Port 5900 is the default port for the VNC (Virtual Network Computing) protocol, corresponding to the screen sharing feature in macOS.
VNC ports have long been prime targets for network scanning tools such as Shodan and Masscan.
VNC is a graphical remote desktop technology based on the RFB (Remote Framebuffer) protocol, originating in the 1990s.
A headless Linux environment refers to an operating system instance with no graphics display directly connected, typically streaming the virtual desktop image to a browser or client via VNC or noVNC.
RDP transmits drawing instructions rather than pixel data, giving it better bandwidth efficiency than VNC; VNC transmits pixel changes in the frame buffer, which is simple to implement but consumes more bandwidth.
VNC (Virtual Network Computing) was released by AT&T Cambridge Laboratories in 1999 and uses the RFB (Remote Framebuffer) protocol.
Traditional remote desktop protocols such as RDP and VNC are primarily optimized for office scenarios, with frame rates typically capped at around 30fps.
