The source provides an extensive overview of bus interconnection within a computer system, starting with the basic definition of a bus and its components like control, address, and data lines. It details several common bus standards, comparing specifications such as clock speed, word length, and data transfer rates for older architectures like ISA, EISA, MCA, and VESA. The bulk of the text focuses on the Peripheral Component Interconnect (PCI) standard, including the role of the PCI-SIG organisation in its development and management. Furthermore, the document meticulously outlines the evolution of PCI technology, describing the features, speed grades, and throughput of Conventional PCI, PCI-X 1.0, PCI-X 2.0, and PCI Express, highlighting their varying levels of backwards compatibility and targeted applications. Finally, it offers a comparative table summarising the speeds of various bus types and lists common devices that utilise the PCI interface.
