These are specifications for the power supplies in PC's.
Pre-Pentium systems had AT supplies, that had manual power on and no support for extremely stable 3.5 volts needed for newer chip cores. Standard +/-5 and +/-12 volts DC were also provided.
ATX supplies provided a standby voltage for the motherboard to be able to signal the power supply that it was ready to be powered on and off. The switch to power on/off is programmable as well as available via a sense pair on from the front panel to the motherboard. The power off timer was also programmable to allow you to force shutdown by holding the power on/of button in for 5 seconds. Additional voltage stability for newer CPU cores was added, as well as new power adapters to support motherboards designed for AMD and Pentium processors. -5volts is an optional voltage in the ATX spec.

The differences between AT & ATX power supply are the connector and output voltage.
ATX is has a 20-pin connector for mainboard power while AT has two six-pin connectors.
