What is one function of adapter cards?

• A. To improve battery life
• B. To increase the computer's display resolution
• C. To add controllers for specific devices
• D. To enhance network security

Answer: (C)

Adapter cards, also known as expansion cards, serve various functions within a computer system, one of which is to add controllers for specific devices. This function is crucial because it allows the computer to communicate with and manage various peripheral devices that might not be supported by the motherboard's built-in components. For instance, a sound card can enhance audio output capabilities, a graphics card can improve visual performance, and a network card can enable wireless connectivity. Each adapter card essentially acts as a specialized controller that facilitates specific tasks, improving the overall functionality and versatility of the computer system. In contrast, improving battery life primarily pertains to mobile devices and is not a function of adapter cards. The role of increasing display resolution is specifically associated with graphic cards, but that is just one subset of adapter cards. Enhancing network security involves software and protocols rather than hardware functions provided by adapter cards.
