The correct answer is Secondary memory.The most common secondary storage devices for use with microcomputers are the floppy disk and hard disk. A floppy disk consists of a thin flexible plastic disk that is coated with a magnetizable substance like oxides of iron or chromium (or a combination of the two).Secondary memory: Secondary memory is computer memory that is non-volatile and persistent in nature and is not directly accessed by a computer/processor.It allows a user to store data that may be instantly and easily retrieved, transported and used by applications and services. Secondary memory is also known as secondary storage.Additional InformationFirmware: firmware is a specific class of computer software that provides the low-level control for a device's specific hardware.Interpreter: an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program.Hardware: Computer hardware includes the physical parts of a computer, such as central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware.
