The POST is special software stored on your system’s read-only memory, which runs every time your machine boots. It runs a check on system components to ensure they are working properly (e.g., your keyboard and mouse).
We are dedicated to bringing you the very best practice tests, flashcards and study guides to help you prepare for and pass the test that stands between you and the rest of your life.
