What is secondary memory example 10?

Secondary memory examples include hard drives, SSDs, USB drives, CDs, DVDs, Blu-ray discs, memory cards, magnetic tapes, cloud storage, and external hard drives. These devices store data permanently, even when the computer is off.

Why do we call them “secondary” storage devices?

They are called secondary because they provide long‑term storage for data instead of the primary memory (RAM) which loses data when the system powers off.These are non‑volatile and hold files, applications and backups.

Can a USB flash drive or a memory card be considered a secondary storage device?

Yes, both USB flash drives and memory cards fall under secondary storage. They use flash memory to store data permanently and are very portable for transferring files between devices.

How do secondary storage devices differ in access speed and purpose?

Some devices like SSDs offer very fast access and are suitable for tasks still in use, while others like optical discs or magnetic tapes are slower and best for long‑term storage or backups.The choice depends on how you’ll use the data. 

What factors should I consider when choosing a secondary storage device?

Look at storage capacity, speed, durability, portability, and cost. For example, choose large‑capacity HDDs for cheap storage or SSDs for faster access.Also ensure compatibility with your device and purpose.

What are 5 examples of storage devices?

Five common storage devices are hard drives, SSDs, USB flash drives, CDs and memory cards.They help you save and access data whenever needed.
