Expansion Cards
Expansion cards refer to circuit boards designed to be added into a computer system to enhance, extend or upgrade its functionality beyond what's provided by the motherboard. These cards are typically inserted into expansion slots on the motherboard and communicate with the CPU via the system bus. They can add features such as improved graphics rendering, sound processing, network connectivity, and data storage capabilities. Expansion cards come in various forms, including video cards, sound cards, network interface cards (NICs), TV tuner cards, and RAID controllers, among others. They are essential for computer users looking to customize their systems or improve performance in specific areas.
