Acronyms like DUI and DWI are something that a San Antonio DWI attorney knows a great deal about, but many computer users might not be aware of the laws and penalties for various offenses. DUI or driving under the influence is probably a more well known acronym than XGA (eXtended Graphics Array), but it is much more dangerous.
