The list on this page is a compilation of such, technical, IT-related acronyms and abbreviations. Its entries were taken from the realms of both, hard- and software technology. It is intended to serve as a reminder and/or quick reference rather than as a glossary/encyclopedia. For this reason and in order to accommodate all entries on a single page, it does not provide any definitions or (furthergoing) information on the meaning and/or origin of the abbreviated terms.
