What is TightVNC and how does it work?
TightVNC is a remote access software that allows users to connect to and control another computer over a network connection. It makes use of the Virtual Network Computing (VNC) protocol, which transmits keyboard and mouse events from the client to the server, and sends back screen updates to the client. This allows users to operate a remote computer as if they were sitting right in front of it, facilitating tasks like technical support, remote work, and server management.
The primary mechanics involve two components: the TightVNC server and the TightVNC viewer. The TightVNC server runs on the machine you want to control, while the viewer runs on the client machine from which you want to initiate the control session. After establishing a connection using an IP address, the viewer sends input commands to the server, which then processes them in real-time, ensuring a seamless interaction.
