that the case and motherboard from different manufacturers. You tell him that there is a case and

standard is known as the:

A.
AT Form Factor.

B.
ATX Form Factor.

C.
Micro-AT Form Factor.

D.
Low profile extended (LPX) and Mini-LPX Form Factor.

Explanation:
The ATX (for Advanced Technology Extended) form factor was created by Intel in 1995. It was the
first big change in computer case and motherboard design in many years. ATX overtook AT
completely as the default form factor for new systems. ATX addressed many of the AT form
factor’s annoyances that had frustrated system builders. Other standards for smaller boards
(including microATX, FlexATX and mini-ITX) usually keep the basic rear layout but reduce the size
of the board and the number of expansion slot positions.
