Difficulty: Easy
Correct Answer: Secondary storage device
Explanation:
Introduction / Context:
This question deals with the difference between volatile and non volatile storage in a computer system. When working on a document or program, your changes are stored in memory, but if you want them to remain available after you shut down the computer, you must save them to a suitable storage device. Knowing which type of storage keeps data even when power is off is fundamental to understanding how computers manage files and is often tested in computer awareness exams.
Given Data / Assumptions:
Concept / Approach:
Secondary storage devices are non volatile media used to store data and programs permanently or for long periods. Examples include hard disks, solid state drives, optical discs and USB flash drives. Data saved to these devices persists even when power is switched off. In contrast, primary storage, commonly RAM, is volatile and loses its contents when power is removed. The motherboard is the main circuit board, not a storage device. Cache memory is a small, fast type of volatile memory that also loses data when power is off. Therefore, when the question refers to data that remains intact after shutdown, it is clearly pointing to secondary storage devices as the correct answer.
Step-by-Step Solution:
Verification / Alternative check:
System documentation and basic computer textbooks describe RAM and cache as volatile memory used while the computer is running and secondary storage as the place where files, operating systems and applications are stored permanently. When you shut down a computer, open files that were not saved to disk are lost, but files that were saved to secondary storage remain and can be reopened later. Operating systems also present drives and partitions from secondary storage devices in file explorers, reinforcing their role as the main destination for saving work. This consistent information across sources confirms that secondary storage devices are the correct answer.
Why Other Options Are Wrong:
Common Pitfalls:
Some learners confuse primary and secondary storage because both words sound important. A good rule is that primary storage is the main working memory used during processing, and it is usually volatile, while secondary storage is where you keep files and programs for long term use. Another pitfall is to view the motherboard as the central component and assume it must store everything. In reality, it only provides connections for storage devices. When a question mentions data remaining after power is off, think non volatile storage and choose secondary storage device.
Final Answer:
When you save data so that it remains after the computer is turned off, it is stored on a Secondary storage device.
