ATX stands for Advanced Technology (e)Xtended, a form factor (layout/design, in computer jargon) that places memory and cards (like video cards) perpendicular to the motherboard. This is the dominant form factor for desktop computers.
ATX (Advanced Technology Extended) is a combination of standards for computer system power supplies and chassis dimensions. It was developed as a replacement for the once-common AT form factor.
ATX and mATX
Form Factor determines if something is the right size and shape to fit in a given case. Most cases are ATX. If you get an ATX case, your motherboard and expansion cards must also be ATX. micro-ATX and miniATX are also different kinds of form factor.
There are many types of cables: Some of which I know include: The standard 2 or 3 prong socket-style, used for most ATX, ITX or other motherboard power supply connections, used in computers and flatscreen televisions. A very similar idea, except with round connectors, only having 2 "pins", and the connector being much smaller. The very common barrel-DC jack, simply looks like a small cylinder with metal inside and out, one for positive and one for negative And for america, the all-standard american jack, two simple thin rectangular prongs, sometimes only fits in one way due to polarized AC.

The ATX power supply and AT power supply had different connections for the computer motherboard. Also the ATX power supply had provision for some parts of the power supply to be switched on-and-off by the electronics on the motherboard, possibly under the control of software. With an AT power supply it necessary for the user to physically operate a switch. This control feature means that a computer that has an ATX power supply can provide, for example, a "wake-on-LAN" or "wake-on-modem" feature whereby the computer will switch itself on if their a signal on the ethernet cable or modem cable. If necessary it should be possible to adapt an ATX power supply to replace an AT power supply. This could be done by finding an adapter cable. The mother board cable from the ATX power supply would then plug into the adapter cable and the adapter cable would plug into the motherboard.
