What is PCI and how did it originate?
The Peripheral Component Interconnect (PCI) standard was introduced in 1993 by Intel Corporation as a way to connect hardware components to a computer’s motherboard. It was designed to replace the existing ISA (Industry Standard Architecture) and EISA (Extended Industry Standard Architecture) bus standards, which were becoming outdated and limited in their capabilities. PCI was a significant improvement over its predecessors, offering higher speeds, greater flexibility, and better scalability. The first version of PCI, known as PCI 1.0, had a bandwidth of 133 MB/s and was widely adopted by the computer industry.
As the computer industry evolved, so did the PCI standard. New versions were released, each offering improved performance, features, and compatibility. For example, PCI 2.1, released in 1995, increased the bandwidth to 266 MB/s, while PCI-X, introduced in 1999, boosted the bandwidth to 1 GB/s. The PCI Special Interest Group (PCI-SIG) was formed to oversee the development and maintenance of the PCI standard, ensuring that it remained relevant and effective in meeting the needs of the rapidly changing computer landscape. Today, the PCI standard is still widely used, although it has undergone significant modifications and improvements over the years to keep pace with advances in technology.
