Liitäntäkortin

Liitäntäkortti, known in English as an interface card or expansion card, is a printed circuit board that allows a computer to connect to and communicate with other devices or expand its functionality. These cards are typically installed into expansion slots on the computer's motherboard, such as PCI, PCIe, or older ISA slots.

The purpose of a liitäntäkortti is to add capabilities that are not built into the motherboard. Common examples include graphics cards for enhanced display output, sound cards for audio processing, network interface cards (NICs) for internet connectivity, and USB expansion cards for additional ports. Some specialized cards might offer hardware acceleration for specific tasks, connect to external storage systems, or provide input/output for industrial or scientific equipment.

The design and functionality of liitäntäkortti have evolved significantly over time. Early computers had fewer integrated components, making expansion cards essential for basic operations. Modern motherboards often have many functions integrated, reducing the necessity for add-on cards for common features. However, for high-performance requirements, specialized or high-end expansion cards remain crucial components in many computer systems. The selection of a liitäntäkortti depends on the intended use of the computer and the compatibility with the motherboard's expansion slots and system architecture.
