VNC (Virtual Network Computing) provides remote desktop access, allowing users to connect to and control a computer from a remote location. This capability is essential for scenarios where users need to troubleshoot issues, manage resources, or access files on another machine without being physically present at that location.

In the context of remote desktop access, VNC transmits the graphical screen display from the remote computer to the local device while sending keyboard and mouse input back to the remote system. This functionality is instrumental in providing support and access to various applications or environments across different geographic locations, making it an invaluable tool for IT support and remote work.

The other types of systems mentioned, such as file synchronization, database management, and web hosting services, serve entirely different purposes and do not relate to the main function of VNC, which is focused on enabling users to operate and interact with remote desktops directly.
