Hey, #fediverse! Allow me to introduce you to 2 of the best #websites I've ever used.

1. #FileInfo. This site allows you to get information on virtually any file extension you can think of, including file type (text/binary), the developer of the file type, and programs that can open that file. Simply enter the file extension into the search field and hit enter, and the details on that file extension are right there! File Info can be accessed at https://fileinfo.com/. You can also pull up an entry directly by adding /extension/file_extension to the end of the URL. For example, https://fileinfo.com/extension/exe.
2. #TechTerms. Similar to File Info, Tech Terms is a database of basically any computing/technology term you can think of. Again, enter the term you want into the search box and hit enter, and the entry for that term will be shown right away. What's also cool about this site is that after each entry, there is a heading for citation links, so you can include the entry in an essay, dissertation or other publication. Also, if there is a noteworthy term in a File Info entry that is in the Tech Terms dictionary, the File Info entry will hyperlink to it. Tech Terms also has a free app for #iOS, though I'm not sure about #Android. In case you haven't guessed already, File Info and Tech Terms are from the same developers. Tech Terms can be accessed at https://techterms.com. You can also append /definition/term to the end of the URL to access a result directly, for example https://techterms.com/definition/website.
All these websites are #accessible for the #blind and #VisuallyImpaired for use with #ScreenReaders, such as #JAWS or #NVDA. In the case of Tech Terms, the app is also accessible with Apple's built-in #VoiceOver screen reader.
