Memory Loses Data When Power Is Off
The question asks to identify the type of computer memory that loses its stored information when the power supply is interrupted. This characteristic defines a specific category of memory.
Understanding Volatile Memory
Volatile memory is a type of computer memory that requires constant power to maintain the stored information. When the power supply is turned off or interrupted, all data stored in volatile memory is lost.
- Example: Random Access Memory (RAM) is a common type of volatile memory used as the main working memory in computers.
Analyzing Other Memory Types
Let's look at why the other options are not the correct answer:
- Optical memory form: This refers to storage like CDs or DVDs, which are typically non-volatile.
- Magnetic memory set: Storage like hard disk drives (HDDs) uses magnetic principles and is non-volatile, retaining data without power.
- Non-volatile memory type: This is the opposite of what the question describes. Non-volatile memory retains data even when power is off (e.g., ROM, SSDs, HDDs).
Therefore, the memory type that loses data when the power is turned off is volatile memory.
