TightVNC uses so-called "tight encoding" of areas, which improves performance over low bandwidth connection. It is effectively a combination of the JPEG and zlib compression mechanisms. [5] [6] It is possible to watch videos and play DirectX games through TightVNC over a broadband connection, albeit at a low frame rate. [citation needed]
For example, Apple Remote Desktop for Mac OS X (and "Back to My Mac" in versions 10.5 through 10.13) interoperates with VNC and will connect to a Unix user's current desktop if it is served with x11vnc, or to a separate X11 session if one is served with TightVNC. From Unix, TightVNC will connect to a Mac OS X session served by Apple Remote ...
RFB ("remote framebuffer") is an open simple protocol for remote access to graphical user interfaces.Because it works at the framebuffer level it is applicable to all windowing systems and applications, including Microsoft Windows, macOS, the X Window System and Wayland.
RealVNC is a company that provides remote access software. Their VNC Connect software consists of a server (VNC Server) and client (VNC Viewer) application, which exchange data over the RFB protocol to allow the Viewer to control the Server's screen remotely.
UltraVNC allows the use of a remote computer as if the user were in front of it. This is achieved by sending mouse movements and key-presses to the remote computer, and replicating the remote computer's display (subject to differences in resolution) locally in real time.
A reverse connection is usually used to bypass firewall restrictions on open ports. [1] A firewall usually blocks incoming connections on closed ports, but does not block outgoing traffic . In a normal forward connection, a client connects to a server through the server's open port , but in the case of a reverse connection, the client opens the ...
Loopback (also written loop-back) is the routing of electronic signals or digital data streams back to their source without intentional processing or modification. It is primarily a means of testing the communications infrastructure. Loopback can take the form of communication channels with only one communication endpoint.
Under HTTP 1.0, connections should always be closed by the server after sending the response. [1]Since at least late 1995, [2] developers of popular products (browsers, web servers, etc.) using HTTP/1.0, started to add an unofficial extension (to the protocol) named "keep-alive" in order to allow the reuse of a connection for multiple requests/responses.
