What type of current is required for all components inside a computer?

The correct answer is that all components inside a computer require DC (Direct Current). Inside computers, components such as the CPU, memory, and storage devices operate on low voltage and require a steady flow of electricity, which is provided in the form of direct current.

This steady supply is crucial for the stable and reliable operation of electronic circuits. Unlike AC (Alternating Current), which periodically reverses direction and is used to power homes and appliances, DC provides a constant voltage that ensures all components function correctly and consistently.

While AC is frequently converted to DC using power supplies in computers to meet the specific voltage and current requirements of internal circuits, the essential functioning of components fundamentally relies on direct current. High voltage (HV) is not directly applicable to typical computer components, as they are designed to operate on much lower voltages. Radio frequency (RF) is also not relevant in this context, as it pertains to electromagnetic waves used in communication technologies, not the power requirements of computer components.
