Liitäntäkorttien

Liitäntäkorttien, also known as interface cards or expansion cards, are electronic components that are plugged into expansion slots on a computer's motherboard. They provide additional functionality to a computer system that is not built into the motherboard itself. These cards can range from simple network interface cards (NICs) that allow a computer to connect to a network, to more complex graphics cards that accelerate video processing for gaming and other demanding visual applications.

Other common types of liitäntäkorttien include sound cards, which enhance audio input and output, and storage controllers, which manage hard drives and solid-state drives. Modems, once prevalent, allowed computers to connect to telephone lines for dial-up internet access. USB expansion cards can add more USB ports to a system, increasing connectivity options for peripherals.

The purpose of liitäntäkorttien is to offer modularity and upgradeability. Instead of requiring a completely new computer for a specific need, users can purchase and install an appropriate expansion card. This allows for customization based on individual requirements and budget. The technology of liitäntäkorttien has evolved significantly, with older technologies like ISA and PCI being replaced by faster and more capable interfaces such as PCIe.
