TightVNC is a free remote control software derived from the popular VNC software. With TightVNC, you can see the desktop of a remote machine and control it with your local mouse and keyboard, as if you were doing it in front of the computer.
TightVNC can be used to perform remote control and administration tasks in Windows, Unix, and mixed network environments. This can be very useful for distance learning and remote customer support.
TightVNC provides these features that are normally missing in standard VNC:
File transfers in versions for Windows.
Support for the video mirror driver (Windows 2000 and later).
Scaling Remote Desktop (Viewer for Windows and Java Viewer).
Effective "Tight" coding with optional JPEG compression.
Access to the enhanced web browser.
Support for two passwords, full control and read only.
