PCIeliitännän

PCIeliitännän refers to a type of electrical connector or interface, commonly found in computing hardware. The "PCI" part typically stands for Peripheral Component Interconnect, a widely used bus standard for connecting hardware components within a computer. The "liitännän" is a Finnish word meaning "connector" or "interface." Therefore, PCIeliitännän can be understood as a PCI connector or PCI interface.

These connectors facilitate communication between the central processing unit (CPU) and peripheral devices such as graphics cards, network cards, sound cards, and storage controllers. Historically, PCI slots were a standard feature on motherboards, allowing users to expand their computer's capabilities by adding or upgrading components. The physical form of a PCI connector consists of a series of pins that align with corresponding contacts on an expansion card.

Over time, the PCI standard has evolved into faster and more advanced versions, including PCI-X and PCI Express (PCIe). While the original PCI bus is largely obsolete in modern high-performance systems, the underlying principle of a standardized interface for component communication remains. Understanding PCIeliitännän provides context for the evolution of computer hardware architecture and the development of expansion slot technologies.
