Web-Based Instruction (WBI)
Web-based Instruction is delivered over public or private computer networks and displayed by a Web browser.  WBI is available in many formats and several terms are linked to it; online courseware, distance education online, etc.  WBI is not downloaded CBT, but rather on-demand training stored in a server and accessed across a network.  WBI can be updated very rapidly, and access to the training is controlled by the training provider.
