Detailed explanation-1: -Random access memory (RAM) is volatile primary storage. Once the computer is switched off the data and instructions held in RAM are lost.
Detailed explanation-2: -Random Access Memory is volatile. That means data is retained in RAM as long as the computer is on, but it is lost when the computer is turned off. When the computer is rebooted, the OS and other files are reloaded into RAM, usually from an HDD or SSD.
Detailed explanation-3: -Does RAM lose data when turned off? RAM is often referred to as volatile memory, because anything contained in RAM is considered lost when a computer is switched off. Indeed, all data is lost from RAM when the power supply is disconnected; so it is volatile in this context.
Detailed explanation-4: -RAM is volatile memory, which stores data in a single transistor and capacitor. This means it needs a constantly recycled charge to hold its data. If the power is turned off, it cannot refresh the data and it is lost. This is known as DYNAMIC memory.
