• "application software" is a main type of software (e.g., word processors, browsers).
• "operating system" (e.g., Windows, macOS) is system software, a main software type.
• "central processing unit (CPU)" is hardware, the brain of the computer.
• "basic input/output system (BIOS)" is firmware (a type of low - level software that initializes hardware during boot - up), and it can be considered a type of software - related component for system startup.
• "hard disk drive" is hardware (stores data physically).
