The main hardware components of a standard computer system consist of the essential physical parts required to process data, execute instructions, and maintain system functionality. These core components include the Central Processing Unit (CPU), which serves as the primary computational engine and brain of the computer; Random Access Memory (RAM), which provides temporary, high-speed working storage for active applications; the Motherboard, which acts as the central circuit board connecting all parts together; the Hard Disk Drive or Solid-State Drive, which provides permanent storage for the operating system and user files; and the Power Supply Unit (PSU), which converts electricity from an external outlet into regulated electrical power for all internal parts.
