Acronyms

Some acronyms and abbreviations common in electronics. This list doesn't aim for completeness; there are other sites for that. Some list so many acronyms that any given acronym has dozens of descriptions, and then it doesn't help either. I don't want to fall in the trap this site has fallen into and provide an acronym for “Vertically Mounted Battery” (indeed, VMB), but fail to mention RAM in the electronics category. That's why I stick to the most used ones. If you think that an important acronym is missing here, please let me know.
