Description:

The enhanced version of VNC, called TightVNC (grown from the VNC Tight
Encoder project), which is optimized to work over slow network
connections such as low-speed modem links. While original VNC may be
very slow when your connection is not fast enough, with TightVNC you can
work remotely almost in real time in most environments. Besides
bandwidth optimizations, TightVNC also includes many other improvements,
optimizations and bugfixes over VNC. Note that TightVNC is free,
cross-platform and compatible with the standard VNC.
