Modern PCs often feature various expansion cards that enhance and extend their capabilities. Graphics cards, or GPU (Graphics Processing Unit) cards, are one of the most common expansion cards, providing high-performance graphics rendering for gaming, content creation, and video playback. Network Interface Cards (NICs) offer additional network connectivity options, allowing users to customize their networking capabilities beyond the onboard Ethernet. Sound cards provide improved audio processing, catering to audiophiles, content creators, or gamers seeking enhanced sound quality. Wi-Fi cards enable wireless connectivity, allowing PCs to connect to Wi-Fi networks without relying on Ethernet cables. Storage expansion cards, like RAID controllers, facilitate the management and acceleration of multiple storage drives in various RAID configurations. USB expansion cards add extra USB ports for increased connectivity options. Capture cards are utilized for capturing and recording audio/video content from external sources, serving content creators and streamers. These expansion cards collectively enable users to tailor their PC to specific needs, whether it be for gaming, multimedia production, or networking requirements.
