The full ATX motherboard size is 12 in long by x 9.6 in wide (305 mm x 244 mm). Since it came out in 1995, the ATX computer form factor has replaced the old AT form in virtually all computers. ATX means Advanced Technology Extended.
Basic difference between these are :- AT means "Advance Technology" while ATX is used for "Advance Technology Extended" SMPS. With respect to AT SMPS, ATX has an extra Plug of +12v Supply for Motherboard. It has four wires connected in square size plug. Two of them are Yellow and other two are black.
Extended Memory 64 Technology
Extended ASCII is 8-bit encoding which is wider than standard ASCII and also includes all characters from standard ASCII encoding.ASCII is 7-bit, 128 possible values; Extended ASCII is 8-bit , 256 possible value;128 first characters of Extended ASCII is the same as ASCII, next 128 are additional. This why it is called Extended ASCII.What is ASCII?ASCII is mainly English language characters encoding, that is used for representation of text information.

BTX, ATX, ITX, and Extended ATX are motherboard form factors that define their dimensions, mounting points, and layout. BTX (Balanced Technology Extended) aims for better thermal management and airflow, while ATX (Advanced Technology eXtended) is a widely used standard known for its versatility and expandability. ITX (Information Technology eXtended) is a smaller form factor ideal for compact builds, and Extended ATX (E-ATX) offers additional space for more components and features compared to standard ATX. Each form factor caters to different needs in terms of space, performance, and system design.
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.
Advanced Technology eXtended. It is a formfactor and the successor to AT.

The ATX (Advanced Technology eXtended) and BTX (Balanced Technology eXtended) port clusters refer to standards for motherboard design and layout in personal computers. The ATX standard, introduced in 1995, specifies dimensions, mounting points, and power connections, promoting better airflow and component accessibility. BTX was developed later to enhance thermal management and improve system cooling by reorienting components, although it did not gain widespread adoption. Both standards dictate how ports and connectors are arranged on motherboards to ensure compatibility and functionality within PC cases.
Motherboard form factors refer to the standardized dimensions and layouts of motherboards, which determine compatibility with cases and components. Common examples include ATX (Advanced Technology eXtended), which is widely used for desktop systems; MicroATX, which is a smaller variant of ATX; and Mini-ITX, designed for compact systems. Other form factors include E-ATX for high-performance systems and FlexATX for small form factor builds. Each form factor has specific size, slot, and power connection configurations tailored for different use cases.
The motherboard form factor that measures 12 inches by 9.6 inches is the ATX (Advanced Technology eXtended) form factor. This size is commonly used in a variety of desktop PCs and is known for providing a good balance of expandability, features, and compatibility with standard cases. Other variations, such as the microATX, are smaller but retain compatibility with ATX cases.
