The full form of ATX is Advanced Technology eXtended. This term refers to a motherboard specification that was developed by Intel in 1995 as an improvement over the earlier AT (Advanced Technology) specification. The ATX standard allows motherboards to have more features and improve system performance by providing better power supply connections, enhanced expandability options, and improved cooling.

The ATX specification is widely used in desktop computers, and it has defined dimensions, mounting points, and connector locations, which ensure compatibility among different components and cases. This has made the ATX form factor a popular choice for a wide range of applications, from basic computers to high-performance gaming rigs.

In contrast to the other options, none of them align with the established ATX standard or its intended meaning. Advanced Transfer, Advanced Technical, and Advanced Technology eXperiment do not correspond to any recognized computer hardware specification or technology, underlining why the correct choice is the full form linked to the well-known motherboard standard.
