Understanding Volatile Memory
Volatile memory is a type of computer memory that requires power to maintain the stored information. When the power is turned off, all data stored in volatile memory is lost. This is why it is considered temporary storage.
Types of Memory
- Primary Memory: This includes RAM (Random Access Memory), which is the main memory used by computers to store data that is actively being used or processed. When the system is powered down, all data in RAM is erased, making it volatile.
- Secondary Memory: This type includes hard drives, SSDs, and other storage devices that retain data even when powered off. It is non-volatile and thus retains information permanently or until it is intentionally deleted.
- Cache Memory: Cache is a smaller, faster type of volatile memory that provides high-speed data access to the CPU. It is also erased when power is lost, but it primarily serves as a temporary storage for frequently accessed data.
- Optical Discs: These are a form of secondary storage (like CDs and DVDs) that retain data without needing power. They are considered non-volatile.
Conclusion
The correct answer to the question is option 'A' – Primary Memory. This is primarily because primary memory, specifically RAM, is designed for temporary data storage and is wiped clean when the power supply is interrupted. Understanding the characteristics of different memory types is crucial for grasping how computers manage data.
