except RAM all are secondary memory
Explanation:
The secondary storage devices which are built into the computer or connected to the computer are known as a secondary memory of the computer. It is also known as external memory or auxiliary storage.
The secondary memory is accessed indirectly via input/output operations. It is non-volatile, so permanently stores the data even when the computer is turned off or until this data is overwritten or deleted. The CPU can't directly access the secondary memory. First, the secondary memory data is transferred to primary memory then the CPU can access it.
RAM:
RAM (Random Access Memory) Random access memory which is also known as RAM is generally known as a main memory of the computer system. It is called temporary memory or cache memory.
