What is a VNC Viewer?

A VNC (Virtual Network Computing) viewer is a software application that allows users to access and control a remote computer desktop through a network connection. The remote desktop manager works by transmitting keyboard and mouse events from the viewer's local computer to the remote pc, while transmitting the remote desktop image back to the viewer's monitor. This enables the viewer to interact with the remote computer as if they were sitting in front of it.

VNC viewers are often used for remote technical support, remote access to servers and workstations, and remote collaboration.
