The PCI (Peripheral Component Interconnect) bus is used for connecting peripheral devices to a computer's motherboard. Here are its main purposes:
-
Device Communication: It allows various hardware components, such as graphics cards, network cards, and storage controllers, to communicate with the CPU and memory.
-
Expansion Slots: PCI provides expansion slots on the motherboard, enabling users to add or upgrade hardware components easily.
-
Data Transfer: It facilitates high-speed data transfer between the CPU and connected devices, improving overall system performance.
-
Standardization: PCI serves as a standardized interface, ensuring compatibility between different hardware manufacturers.
