Basic Assurance Test ou Batch File

This term can have two meanings, depending on the context:

(1) A keyboard controller command (circuit called 8042 on the early PCs) that tests the keyboard. This command is sent to the keyboard controller during POST.

(2) A file type called "batch file" used by Windows and DOS systems. In this kind of file you can have several command-line commands to be executed instead of having to type them one by one on the command prompt. The most famous batch file with BAT extension is Autoexec.bat, which is run every time the operating system is loaded.
