Common Types of Expansion Boards
Graphics Cards (GPU): Enhances the computer's ability to render images, video, and 3D graphics.
Sound Cards: Improves audio processing and provides high-quality input/output for speakers and microphones.
RAM Modules: While often referred to separately, memory expansion cards can increase the system's volatile memory.
Storage Controllers: Adds ports for additional hard drives or high-speed SSDs (like NVMe expansion cards). Why the other options are incorrect:
A) Writing tablet: An external input device (peripheral) used by artists or for digital signatures; it is not a board installed inside the computer.
B) Keyboard: A standard external input device used for typing.
D) NIC controller: A Network Interface Card (NIC) is actually a type of expansion board (or built-in chip). While it improves connectivity, the term "expansion board" is the broader, more accurate category for any board used to "enhance capabilities" as described in the question.
