Question 1

What is the difference between SSD and HDD storage?

Accepted Answer

SSDs use flash memory with no moving parts while HDDs use spinning magnetic disks

Answer

SSDs store data on flash memory chips with no moving parts, offering faster speeds and greater durability. HDDs use spinning magnetic platters read by a mechanical arm.

Answer

Firmware is specialized software permanently stored on a hardware device's memory chip that provides low-level control for the device's specific hardware functions.

Question 5

What is the role of cache memory in a computer system?

Accepted Answer

It provides ultra-fast temporary storage for frequently accessed data to speed up processing
