CPU
ALU
Floppy disk
Mouse E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is C. Floppy disk.
A secondary memory device is a storage device that is not directly accessible by the CPU. It is used to store data and programs that are not currently being used by the CPU. Secondary memory devices are typically slower than primary memory devices, but they have a much larger capacity.
A CPU (central processing unit) is the main processing unit of a computer. It is responsible for carrying out the instructions of a computer program.
An ALU (arithmetic logic unit) is a part of the CPU that performs arithmetic and logical operations.
A mouse is a pointing device that is used to control the cursor on a computer screen.
E is not a correct answer because it is not a secondary memory device.
