Intranet technology is the application of Internet tools in local networks. Due to the diversification of hardware and the need for international cooperation, cross-platform systems with network access are required for computer-based training (CBT). The latest advances in Web technology make it feasible to have interactive CBT on the Web: Web-based training (WBT). It is possible to convert existing interactive learning programs to Intranet technology. This approach combines the evaluated contents of excellent learning resources with the technical advantages of Web technology.
