Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Where are programs executed from?

A	Primary storage:RAM & ROM
B	Peripherals
C	Secondary storage:Hard disk/SSD
D	Tertiary storage:External mounted drives

Explanation:

Detailed explanation-1: -The CPU executes a program that is stored as a sequence of machine language instructions in main memory. It does this by repeatedly reading, or fetching, an instruction from memory and then carrying out, or executing, that instruction.

Detailed explanation-2: -Programs that are currently running, and open files, are stored in RAM; anything you are using is running in RAM somewhere. As soon as the electricity to the RAM is cut, it forgets everything; that’s why an unsaved document is lost if the computer locks up or there is a power failure.

Detailed explanation-3: -The correct answer is cache memory. Cache memory is a memory that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. It is used to store program data that is currently being executed in the CPU.
