Correct Answer:
Option C —
Data stored in Random Access Memory is lost when power goes off and it will have to be recreated
This is because RAM is volatile memory. Unlike a hard drive or SSD (Non-volatile memory), RAM requires a constant flow of electricity to maintain the data stored within its cells.Why is the data lost?RAM uses tiny capacitors to store data as electrical charges. When the power is cut, these capacitors quickly discharge, and the binary information (1s and 0s) they were holding simply disappears. This is why you lose unsaved progress on a document if your computer crashes before you hit "Save."How it works when you reboot:Startup: When you turn the computer back on, the RAM is empty.Loading: The Operating System (OS) and necessary files are copied from the Hard Drive (Permanent storage) back into the RAM (Active workspace).Speed: We use RAM despite this flaw because it is significantly faster than permanent storage, allowing the CPU to access data almost instantly.
