“A screencast is a digital recording of computer screen output, also known as a video screen capture, often containing audio narration.” (Wikipedia, retrieved 20:22, 30 July 2007 (MEST).
Screencasts can be used to explain how to use some software. E.g. user interaction is recorded and explanations are given by a voice-over made at recording time or later.
A second use of the word "Screencast" refers to recordings of talks and seminars where slide contents + presenters voice are recorded.

2.2 Video software
You also may just film some user interaction (i.e. via a webcam) or with a camera. But mileage is not so good in most cases. See: video streaming, multimedia container format, etc.
3 In education
Screencasts have been very popular in so-called rapid elearning but also gained a lot of attention trough the success of the Khan Academy or MOOCs.
- "Rapid" refers to production cost, i.e. it is much cheaper to produce screen casts than good written manuals or online interactive contents. In addition, this delivery mode is closer to traditional educational models.
