What best describes Peripheral Component Interconnect (PCI) technology?

Peripheral Component Interconnect (PCI) technology is best described as an industry-standard device bus for all types of expansion devices. This standard allows various hardware components, such as sound cards, network cards, and modems, to connect to a computer's motherboard, enabling efficient communication between the CPU and these peripherals.

The significance of PCI lies in its wide acceptance and support across numerous manufacturers, not just limited to one brand or proprietary systems. This universality means that many devices from different vendors can operate seamlessly in different computer systems that support PCI, fostering compatibility and innovation in hardware development.

Understanding the broad applicability of PCI is essential, particularly in contexts where a variety of expansions and upgrades are necessary for enhancing computer functionality. Unlike proprietary formats or claims of obsolescence, PCI continues to be relevant, especially in legacy systems and applications where backward compatibility is required. This makes it a foundational technology in computer architecture.
