Which of the following can be an internal storage device?

Correct option is C

An internal storage device is one that is installed inside the computer’s system unit and is used to store operating system files, application software, and user data. A hard disk (HDD or SSD) is the primary internal storage device in most computers and laptops. It remains permanently attached to the system unless manually removed.

Important Key Points:

1. An internal hard disk serves as the main data storage unit of a computer.
2. It is directly connected to the motherboard via SATA or NVMe interfaces.
3. Internal storage devices are non-removable during normal usage and boot with the system.

• Compact Disk (CD): An optical storage device, typically used for media or software distribution; read externally through a CD/DVD drive.
• Digital Versatile Disk (DVD): Also an optical storage device, similar to CDs but with larger capacity; again used externally and not part of internal storage.
