Introduction
Netboard is a collaborative whiteboard which intends to use the widely usage of the Internet and its tools to develop a distant learning environment. It has two components for each peer of the communication, one of which is used by an instructor, and the other by students. Each person downloads his or her own version of the program, and either teaches a class, or joins an active teaching, or browse previous sessions. The system has been developed by using Java and Perl programming languages.
