Expansion Cards & Roles for A+
Short answer
Expansion cards extend system capabilities. Video cards handle graphics output and acceleration, NICs provide network connectivity, sound cards offer enhanced audio I/O or processing, and capture cards take external video inputs for recording or streaming. Identify the card by its slot (usually PCIe) and external I/O ports.
Why it appears on the exam
- Given a scenario (e.g., no audio input for recording), select the correct expansion card role and justify the choice. - Identify which slot a video card will require and whether additional power connectors will be necessary.
Key concepts
Concept 1
Required terms
Video card (GPU): An expansion card that provides graphics output and hardware acceleration for visual processing. NIC (Network Interface Card): Card that provides wired or wireless network connectivity; modern motherboards often include integrated NICs. Sound card: Card that provides audio processing and I/O beyond integrated audio capabilities. Capture card: Card used to ingest video input for streaming or recording from external sources.
Example
Replacing a failed onboard NIC in a desktop by installing a PCIe NIC provides immediate wired network capability.

How Expansion Cards & Roles works
Expansion cards extend system capabilities. Video cards handle graphics output and acceleration, NICs provide network connectivity, sound cards offer enhanced audio I/O or processing, and capture cards take external video inputs for recording or streaming. Identify the card by its slot (usually PCIe) and external I/O ports.
Example
A user who wants to stream game footage may need a capture card if they want to record from a console or external camera.
Concept 3
Common confusion
- Installing a capture card when the need is just more display outputs: capture cards ingest video, while GPUs output to displays. - Adding a discrete NIC when the board already has an integrated NIC: check rear I/O before adding hardware.
Example
Upgrading from integrated graphics to a discrete GPU requires checking for an available PCIe x16 slot and sufficient power connectors.
