Lisälaitekortti

Lisälaitekortti, also known as an expansion card or adapter card, is a printed circuit board that can be inserted into an expansion slot on a computer's motherboard to add new functionality or capabilities. These cards allow users to upgrade or customize their computer systems without needing to replace the entire motherboard or computer. Common examples of expansion cards include graphics cards for enhanced visual output, sound cards for improved audio performance, network interface cards (NICs) for internet connectivity, and storage controllers for adding more hard drives or solid-state drives.

Expansion slots, such as PCI, PCIe, and AGP, are specifically designed to accommodate these cards. When a lisälaitekortti is installed, it connects to the computer's bus system, enabling it to communicate with the CPU and other components. This allows the new hardware to be recognized and utilized by the operating system. The specific type of lisälaitekortti and the slot it uses are determined by the computer's motherboard design and its support for various expansion standards. The ability to add expansion cards has been a cornerstone of personal computer expandability, allowing for a high degree of customization and longevity for hardware.
