Final answer:
ROM, HDD, flash drives, and flash memory cards are types of computer memory with HDD, flash drives, and flash memory cards serving as secondary storage, while ROM is non-volatile memory not typically classified as primary or secondary storage.
Step-by-step explanation:
The terms ROM, HDD, flash drive, and flash memory card refer to types of computer memory and storage devices. Each has a specific function within a computer system:
- ROM (Read-Only Memory) is a type of non-volatile memory that is typically used to store firmware or system software that is not intended to be edited or rewritten frequently.
- HDD (Hard Disk Drive) is a type of secondary storage device known for its large storage capacity. It uses magnetic storage to store and retrieve digital information using one or more rigid rotating disks (platters) coated with magnetic material.
- A flash drive, also known as a USB drive, is a portable flash memory storage device that plugs into a computer's USB port. It serves as secondary storage for data transfer between computers.
- A flash memory card is a storage device used in portable devices like cameras, smartphones, and tablets. It is also considered secondary storage and is often used to extend the storage capacity of these devices.
According to the options provided, HDDs, flash drives, and flash memory cards would be classified as b) Secondary storage due to their role in permanently storing data that does not require constant power to maintain. In contrast, ROM would not be classified in any of the given options since it's typically read-only and not used as primary or secondary storage in the same way as RAM or hard drives. ROM is, however, non-volatile, meaning it retains data without power.
