Answer 15

The ARM architecture is developed by ARM Limited, known for efficiency and is commonly used in mobile devices.

Question 16

How does ARM architecture compare to traditional 64-bit operating systems?

Answer 16

ARM architecture is expanding its capabilities, blurring lines with traditional 64-bit operating systems.

Question 17

What does a CPU consist of?

Answer 17

A CPU consists of multiple cores, caches, memory controllers, and sometimes graphics processors.

Question 18

What is the purpose of CPU caches?

Answer 18

Caches are designed to help speed the processing of information into and out of the CPU.

Question 19

How does Hyper-Threading Technology (HTT) affect CPU performance?

Answer 19

HTT increases the throughput of processes by 15% to 30%, making a single physical CPU core appear as multiple cores.

Question 20

How can you check if your CPU supports virtualization?

Answer 20

Check your BIOS for Intel Virtualization Technology (VT) or AMD Virtualization (AMD-V).

Question 21

What is virtualization and why is it resource-intensive?

Answer 21

Virtualization allows running multiple operating systems on one computer. It is resource-intensive because it involves running multiple OS instances simultaneously.
