Which part of the computer is used to permanently store data even when thepower is off?a. RAMb. CPUc. Hard Drived. Cache

To answer the question regarding which part of the computer is used to permanently store data even when the power is off, we can analyze the options provided:

1. RAM (Random Access Memory): This is a type of volatile memory, which means it only holds data while the computer is powered on. Once the power is turned off, all data in RAM is lost.

2. CPU (Central Processing Unit): The CPU is the main processing unit of the computer that executes instructions. It does not store data permanently.

3. Hard Drive: This is a type of non-volatile storage where data is stored permanently, even when the computer is powered off. It retains information such as the operating system, applications, and personal files.

4. Cache: This is a smaller, faster type of volatile memory that provides high-speed data access to the CPU. Like RAM, the cache does not retain data once the power is off.

Conclusion

The correct answer is c. Hard Drive, as it is the component that permanently stores data even when the power is off.
