Introduced in 1995, the ATX was the first PC motherboard to not only include I/O support (serial, parallel, mouse, etc.), but to place all the connectors directly on the motherboard. Prior to the ATX, only the keyboard connector was attached to the motherboard.
Numerous variations of the ATX were subsequently introduced with both smaller and larger form factors, including the microATX, Mini ATX, FlexATX and Extended ATX (see PC motherboards).
The ATX Motherboard
The motherboard glues all the components of a computer system together via its various slots, connectors and ports. In this case, Socket A is for an AMD Athlon XP CPU. DDR slots hold SDRAM memory modules, and the AGP and PCI slots hold the adapter cards. The back panel ports stick through the back of the case. (Image courtesy of ASUSTeK Computer Inc., www.asus.com)
