VNC

Virtual Network Computing (VNC) is a graphical desktop-sharing protocol that allows users to remotely control another computer's desktop interface. Developed by the Olivetti & Oracle Research Lab (ORL) in the late 1990s, VNC enables users to access and interact with a remote computer's desktop environment over the internet or local network.

VNC operates through a client-server model where the server shares its screen and the client views and interacts with it. It is platform-independent, meaning it can be used across different operating systems such as Windows, macOS, Linux, and UNIX. The protocol transmits keyboard and mouse input from the client to the server, updating the display to reflect changes in real-time. VNC was created by ORL, which later became part of AT&T Laboratories Cambridge. Its development started in 1995 and was designed as an open-source tool, making it widely accessible. It's particularly useful for IT support, remote work, and accessing computers without physical presence. Despite the rise of other remote desktop solutions, VNC remains relevant due to its simplicity and versatility.
