VNC stands for Virtual Network Computing, which is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol to remotely control another computer. In the context of Screen Sharing, VNC allows users to view and interact with a desktop environment located on another computer over a network connection.

This technology is essential for remote technical support, as it enables one user to see another user's screen and control the mouse and keyboard as if they were sitting at that computer. Virtual Network Computing works across different operating systems, making it a versatile tool for cross-platform scenarios.

The other options presented don't accurately represent the technology: "Very Network Control," "Visual Network Communication," and "Verified Network Control" do not relate to the established term for desktop sharing in this context. Understanding the correct term—Virtual Network Computing—is crucial for anyone involved in technical support or remote assistance roles, as it establishes a foundational concept of how remote connections are made and managed.
