What is vnc viewer?

VNC Viewer is a remote desktop application that allows users to connect to and control another computer over a network or the internet. It uses the Virtual Network Computing (VNC) protocol to transmit screen images and capture keyboard and mouse inputs from the client device to the host machine. This enables users to access their desktop, applications, and files remotely as if they were sitting in front of the remote computer. VNC Viewer is commonly used for technical support, remote work, and accessing home computers while away.
