POST

(1) (Power On Self Test) A series of built-in diagnostics performed by the BIOS in a PC when the computer is first started. See POST card.

(2) (post) To send a message to a newsgroup or blog or to place a new or revised HTML page on a Web site. This term goes back to the earliest days of manual record keeping, where "to post to an account" meant to make an entry in a paper ledger.

(3) (post) Short for post production.

(4) (POST) An HTTP command used to send text to a Web server for processing. The POST method is widely implemented in HTML files for sending typed-in forms to the server. Both POST and GET are HTTP methods that make requests of the server, but pass parameters to it in a different manner. In some cases, both methods may produce the same results; however, there are many applications where only one of the methods is the appropriate one. See GET.

1.		POST - power-on self-test
2.	(messaging)	post - To send a message to a mailing list or newsgroup. Usually implies that the message is sent indiscriminately to multiple users, in contrast to "mail" which implies one or more deliberately selected individual recipients. You should only post a message if you think it will be of interest to a significant proportion of the readers of the group or list, otherwise you should use private electronic mail instead. See netiquette.
