Understanding Computer Storage

The video tutorial explains the differences between primary, secondary, and tertiary storage, focusing on RAM and ROM. It highlights the volatile nature of RAM and the non-volatile nature of ROM, emphasizing their roles in the boot process and system performance. The tutorial also discusses the speed and capacity differences between primary and secondary storage, illustrating why primary storage is essential for quick data access. The video concludes with a summary and exam preparation tips.

Which of the following is NOT a category of storage devices discussed in the video?

• Quaternary Storage

• Tertiary Storage

• Secondary Storage

• Primary Storage

What is a key difference between primary and secondary storage?

• Primary storage is used for long-term data storage.

• Primary storage is faster in access speed compared to secondary storage.

• Primary storage has a larger capacity than secondary storage.

• Primary storage is non-volatile, while secondary storage is volatile.

Why is RAM considered volatile?

• It loses data when the power is turned off.

• It retains data permanently.

• It is slower than secondary storage.

• It is used for long-term storage.

How does RAM improve system performance?

• By reducing the need for secondary storage.

• By increasing the storage capacity.

• By allowing faster access to instructions.

• By storing data permanently.

What is the primary function of ROM in a computer?

• To store temporary data.

• To execute user programs.

• To hold the initial startup instructions.

• To increase the computer's speed.

What is firmware?

• Software stored on ROM.

• Software stored on RAM.

• Temporary data storage.

• A type of secondary storage.

What is the role of the Power-On Self-Test (POST)?

• To check and initialize hardware components.

• To load the operating system into RAM.

• To store data permanently.

• To increase the computer's processing speed.

When does the computer become aware of the hard drive during the booting process?

• When the computer is turned off.

• After the RAM is cleared.

• During the Power-On Self-Test (POST).

• After the operating system is loaded.

What happens to the instructions in RAM when the computer is turned off?

• They are transferred to ROM.

• They are saved permanently.

• They are lost.

• They are stored on the hard drive.

Why is ROM considered non-volatile?

• It is faster than RAM.

• It retains data even when the power is off.

• It is used for temporary storage.

• It loses data when the power is off.
