  • Fourth generation language (4gl) — A programming language of a higher level than 3GLs such as C or Pascal - that is, the program code is closer to English, and a 4GL function might be the equivalent of many 3GL functions. 4GLs are used for writing software for specialised tasks, such as querying databases. See Programming Language. Frame: A area in a Web page that scrolls independently of the rest of the Web page. A Web page can be divided into multiple frames. For example, a frame can include a navigation bar - as at the ICT4LT website - that always stays on the screen as the user moves around the other pages of the site.
