Which of the following is not correct for non-volatile memory?

Correct option is C

The statement " Data is lost after the PC is off" is incorrect for non-volatile memory. Non-volatile memory retains data even when the power is turned off. This type of memory is designed to store data permanently until it is intentionally erased or overwritten, which is why it is used in devices like SSDs, hard drives, and USB drives.
Important Key Points:
1. Non-volatile memory retains data without requiring power, making it ideal for permanent storage.
2. It is commonly used in storage devices like SSDs, hard drives, and flash drives.
Knowledge Booster:
· Data is retained even after the PC is turned off: This is the defining feature of non-volatile memory.
· It is commonly used for long-term storage: Non-volatile memory is designed for retaining data long-term, unlike volatile memory like RAM.
· Non-volatile memory includes SSDs and Hard Drives: Both of these are examples of non-volatile storage devices.
· It is slower than volatile memory like RAM: This is true because non-volatile memory typically operates at slower speeds compared to volatile memory, which is optimized for fast access during active processes.
