POST

1. When referring to a message board, a post refers to an article published on an Internet newsgroup, forum, or other bulletin board area. It is also the act of publishing such a message.

2. Short for Power On Self Test, the POST is a test the computer must complete to verify all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST the computer will often return a single beep and if unsuccessful will often beep or several times to indicate the error..
