Java Java is a complete programming language. Programs written in Java can be used in a web browser on any type of computer.
Animated GIFs An animated GIF is a sequence of images which are displayed one after the other in rapid succession. This has the effect of displaying an animation.
Sound Sound can be added to web pages. This can be in the form of music playing in the background whilst a page is displayed or noises which are made when options are selected.
Video There are many different systems which can be used to display video over the Internet. Videos require a lot of storage space and take a long time to transmit. Therefore video over the Internet is usually poor quality with a small image size and just a few frames per second. Good quality video can be broadcast with a fast broadband connection.
