How Do You Spell AT BUS ARCHITECTURE?

Pronunciation: [at bˈʌs ˈɑːkɪtˌɛkt͡ʃə] (IPA)

The correct spelling of the term "AT bus architecture" is /ˌeɪ ti ˈbʌs ˈɑːr.kɪ.tek.tʃər/. The "AT" refers to the IBM PC AT, a computer model introduced in the 1980s that used this type of architecture for its expansion slots. The "bus" portion refers to the way in which electronic signals are transmitted between different components within a computer. Overall, the "AT bus architecture" is a specific design used in older computer models that facilitated the connection of peripheral devices such as graphics cards and network adapters.

AT BUS ARCHITECTURE Meaning and Definition

  1. The AT bus architecture refers to the bus system used in the IBM PC AT (Advanced Technology) and subsequent compatible computers. The AT bus, also known as the ISA (Industry Standard Architecture), is a type of expansion bus that allows for the connection of various peripherals and expansion cards to the motherboard.

    The AT bus architecture is a 16-bit bus, meaning it transfers data in 16-bit chunks. It is characterized by its parallel nature, as it has multiple parallel electrical paths for transmitting data between devices. The bus consists of a series of slots on the motherboard, into which expansion cards can be inserted.

    The AT bus architecture supports a wide range of peripherals such as sound cards, network cards, and graphics cards, providing a standardized interface for their connection. It uses a shared bus design, where multiple devices are connected to the same bus and must take turns accessing it. This can result in slower data transfer speeds compared to more modern bus architectures.

    While the AT bus architecture was widely used in the 1980s and 1990s, it has since been largely superseded by faster and more advanced bus systems like PCI (Peripheral Component Interconnect) and its successors. However, it still holds historical significance and understanding its principles can be important when working with older computer systems.
