This statement is incorrect. Main memory, also known as Random Access Memory (RAM), is used temporarily to store information that the CPU needs while a computer is on; it does not store data permanently. When the power is turned off, data in the RAM is lost. Permanent storage is typically achieved with storage devices like hard drives, solid-state drives, or cloud storage where data persists even when the computer is turned off. Understanding the difference between temporary and permanent storage is crucial for IT professionals.
