SMS messaging

SMS is a simple text messaging application for mobile phones, allowing users to communicate asynchronously over mobile networks. SMS messages can be entered manually on the telephone keypad or generated by a computer program. In a learning context, SMS messaging has been used to a limited degree as a means of contact between teachers and students, and between students and other students.

Simulator

A simulator is a device used in training to reproduce the conditions of the working situation, enabling tasks to be learned and practised safely and economically. Common examples are flight and driving simulators.

Streaming media

Streaming is a technology for delivering audio and video in real-time on web sites. Rather than users having to wait for large audio and video files to download before they can be played back, streaming allows playback to commence almost immediately. Streaming media solutions are provided by Microsoft (Windows Media Services), Real Systems (RealServer), Apple (Quicktime Streaming Server) and Adobe (Flash Media Server).
