Why is RAM called volatile memory?
RAM (Random Access Memory) is called volatile memory because the information stored in RAM is lost when the power is turned off. This is in contrast to non-volatile memory, such as hard drives or solid-state drives, where data is retained even when the power is off.
Here are the reasons why RAM is called volatile memory:
1. Information is deleted when the power is off: RAM stores data in electronic circuits that require a constant supply of electricity to maintain their contents. When the power is turned off, the electrical charge in the RAM cells dissipates, causing the stored data to be lost. This makes RAM volatile as it cannot retain data without power.
2. Data can be retrieved: While data is lost when the power is off, RAM provides fast and temporary storage for data that the computer's processor is actively using. The data can be read from and written to at high speeds, allowing for quick access and manipulation. However, once the power is removed, the data is no longer accessible.
3. RAM is very small in size: Volatility is not related to the physical size of the RAM. RAM comes in various sizes and form factors, ranging from small modules used in personal computers to larger modules used in servers. The size of RAM does not determine its volatile nature.
4. There is no prestored programs in RAM: RAM is a type of memory that is used for temporary storage of data while the computer is running. It does not store permanent programs or files. Instead, it holds data that is actively being used by the computer's processor, allowing for quick access and execution.
In summary, RAM is called volatile memory because it loses its stored data when the power is turned off. While it provides fast and temporary storage for actively used data, it cannot retain information without a constant supply of electricity.

Understanding Volatile Memory
RAM, or Random Access Memory, is categorized as volatile memory due to its behavior in relation to power supply. Here’s a detailed explanation:
What is Volatile Memory?
- Volatile memory refers to a type of storage that loses its data when the electrical power is turned off.
- In contrast, non-volatile memory retains its data even without power, like hard drives or flash drives.
Why RAM is Volatile?
- Information Loss: The primary reason RAM is considered volatile is that all stored data is erased once the device is powered down.
- Temporary Storage: RAM is designed to hold data temporarily while a computer is running. It allows fast access to data that the CPU needs in real-time.
Comparison with Non-Volatile Memory
- Speed: RAM is much faster than non-volatile memory, which is why it is used for active processes and tasks.
- Usage: It is used to store the operating system, applications, and data currently being used by the CPU, making it critical for system performance.
Conclusion
- The characteristic of losing all stored information when power is lost is what makes RAM volatile memory.
- This feature is essential for its role as a quick-access storage option during active computing sessions.
In summary, option 'A' is correct because RAM is classified as volatile memory due to its inability to retain data without a power supply.
