What is an expansionslot In the realm of computer hardware, the terms "bus" and "slot" are fundamental to understanding how components communicate and expandPCI - The Peripheral Component Interconnect Bus While often used in close proximity, they represent distinct yet interconnected concepts2025530—Peripheral Component Interconnect Express (PCIe bus) enables fast data transfer from measurement devices to PC memory. A bus acts as the communication highway for data transfer, while an expansion slot provides a physical connection point for devices to utilize that highwayHowever, due to electrical limitations on the lengthofthe wiresbetweentheslotsthe PCI-X specs allow only up to twoslotsto be connected to a singlebus. Recognizing the differences between PCI buses or DIMM slots and understanding the purpose of expansion slots is crucial for anyone delving into computer architecture or performing hardware upgradesChapter 6 Expansion Buses | PPT
At its core, a bus is a communication pathway that allows data to travel between different components inside a computer2010123—Thinkoftheslotas a wall power outlet, and thebusas the wires feeding it.
