Ql. What are the four layers of computer architecture?

• Hardware, Windows, Software, User

• Computer, Operating System, Software, User

• Binary, Hardware, Operating System, Software

• Hardware, Operating System, Software, User

Answer explanation

The hardware will be the medium of all the translation and

conversion of binary text to displayable text that a user

can read. The operating system will be the resource manager

of all the applications and system processes that will execute

different codes to display. The applications are the ones that are

tailor-made for various purposes to be used by a user. And lastly, the user

will be the performer upon doing a task using the computer system.

Where does the CPU store its computations?

• Binary

• Registers

• Processor

• External Data Bus

Answer explanation

After your CPU is done with the registers, it stores its computations in the CPU cache. This is because the processor cache is the second-fastest memory on your computer. The main similarity between the data cache and registers is that they're located on the CPU chip, and are smaller than the system ram.

What is the last step in booting a computer?

• Load up drivers

• Perform a POST

• Execute the bootloader

• User space is launched

• Windows logo shines

Answer explanation

After the operating system is successfully loaded and evaluated to ensure full compliance with onboard hardware, full control of the machine is transferred to it as part of the final stage of the boot process. At this point, the operating system begins to launch any specific applications that it relies on to function successfully.

Which of these are considered I/O devices?, Check all that apply.
