4. vnc and remote desktop (from: the difference between VNC and remote desktop )
VNC
VNC uses the RFB protocol to do screen sharing and remote operation software, developed by the famous AT&T European research laboratory. The client software and server software are required to be used together.
Remote Desktop The
remote desktop uses the RDP (Remote Desktop Protocol) remote desktop protocol. Most Windows support this protocol by default, allowing remote access to the operating desktop.
The difference between RFB and RDP
RFB is to transfer the image to the client after the window is drawn in the video memory on the server side. The client only acts as an image decoding and display role; RDP delegates the work of drawing to the client, and the server needs to understand The client displays the specific conditions of the capabilities in order to make corresponding adjustments.
RFB mainly transmits images, and RDP mainly transmits commands. For general applications, RFB data volume is too large, and RDP has higher requirements on the client. Therefore, RFB is suitable for thin clients and RDP is suitable for low-speed networks.
