Virtual Network Computing

This document provides an overview of Virtual Network Computing (VNC), a remote display system that allows users to view and interact with computers over the Internet from various platforms. Key features include its simplicity, platform independence, and collaborative visualization capabilities. VNC is particularly useful in educational settings, serving as both a lecture and collaboration tool in distributed classrooms. The document discusses applications of VNC, including the use of open-source code and enhanced performance for visualization tasks.
