RAM stands for Random Access Memory. What happens to RAM when the computer turns off?
Correct Answer
disappearsExplanation
When the computer turns off, the RAM loses all the data stored in it. This is because RAM is a volatile type of memory, meaning it requires constant power to retain information. When the power is cut off, the electrical charges holding the data in RAM dissipate, causing the data to disappear. Therefore, the correct answer is that the RAM disappears when the computer turns off.Rate this question:
