What is the difference between rdp and vnc

But, Remote Desktop Protocol is able to send graphics primitives and understands the underlying graphics layout better. In other words, RDP is aware of controls and only the information about the controls is are sent across, but VNC sends actual images across networks. Because of this difference, VNC is relatively less efficient than Remote Desktop, as Remote Desktop is able to significantly compress the data stream. VNC is also better for technical support as it allows sharing a session on the target machine.

Indika, BSc. Your email address will not be published. It makes VNC a good choice for technical support when the remote user can see what the local user does and can take control when needed to help. Popular WEB based screen sharing technologies like WebEx or GotoMeeting provide similar kinds of functionality using cloud based servers to maintain communication. VNC does it using a direct connection.

RDP is inherently Windows technology on the server side because of its core principle of creating a unique Windows login session for each user of the system. VNC supports multiple platforms on the server side allowing sharing screens and keyboards of both Windows and Linux computers including Linux graphical environments. It might explain the desire to standardize on VNC to keep access similar across the board. There are multiple technologies based on and sometimes partially compatible with this technology including some of the WEB based screen sharing applications.

They might claim to have VNC as their primary communication channel, However they might not support complete VNC infrastructure with peer-to-peer connectivity and specific client and server side software. It eliminates the need to install VNC clients on multiple desktop or mobile devices. It can optionally login the user to the remote computer without even asking the user for credentials based on the permissions in the XTAM server itself. In addition to that, XTAM can monitor user keystrokes and even record complete session to the remote computer as video for future learning, sharing or auditing purposes.

It provides a simple and secure method of granting access to remote computers in a controlled way. This article summarizes similarities and differences of RDP and VNC technologies essential to understaning and using distributed computing architecture. What do you think about our assessment?

One more thing: VNC allows you to share a session on the target machine good for tech support and demos where RDP does not. If you have the privileges, you can shadow another user's RDP session or the console session. It's not automatic, but it is possible.

See this page for instructions on how to shadow RDP sessions: oreilly. The primitives elements are obviously different and impossible to convert properly between 2 systems.

XRDP is still aware and is doing quite a bit of work including identifying common things like fonts or simply blocks of the screen that are a single or unchanging color to eliminate sending straight images over the network.

It is a proprietary protocol built by Microsoft to let users to graphically control remote computer. RDP logs in a remote user to the server computer by effectively creating a real desktop session on the server computer including a user profile.

RDP works in the same way as if the user had logged in to the physical server directly. RDP can support multiple remote users logged in to the same server that completely unaware of each other. It is an open platform independent graphical desktop sharing system designed to remotely control another computer. VNC follows the older model of simply showing whatever is on the screen with no forced logins required. VNC connects a remote user to the computer itself by sharing its screen, keyboard and mouse.

Consequently, when several users including the one operating the real physical monitor and keyboard connect to the same server they see the same thing and they type on the same keyboard.

VNC has security implications; if you remote into a machine that an Administrator is logged into, you'll effectively be an Administrator. And if you're both trying to use the computer at the same time, it's even more fun! Similarities between both, Both RDP and VNC technologies require client side and server side software to support communication protocol.

Both technologies use direct peer-to-peer communication.
