Mobile devices do not use hard disk drives. Instead, they use NAND flash memory for their non-volatile storage in combination with RAM to quickly access apps and programs. Mobile devices generally store data in the same way as an SSD does.
Question 16
The correct answer is: b: False
Most modern operating systems have built-in drivers that allow hardware to work at a basic level without needing to install drivers. Internal components, like the fan, CPU, and hard drive may not require drivers. Drivers are only necessary for the hardware or peripheral device.

Question 23
The correct answer is: a: They are harder to upgrade and replace due to integrated components.
Since the internal components are integrated, they are harder to upgrade and replace. The components are often soldered onto the motherboard, preventing components from being upgraded later. For example, it is not possible to swap out the CPU, GPU, or RAM with a newer part.
