3.4 - CPU Features Flashcards
What are the common CPU architectures for operating systems?
Most of the latest operating systems are 64-bit architectures, but older systems might be 32-bit.
What is the maximum amount of information a 32-bit processor can access?
A 32-bit processor can access up to 2 to the 32nd power of information, which is just over 4 billion values.
What is the maximum amount of information a 64-bit processor can access?
A 64-bit processor can access up to 2 to the 64th power of information, which is an extremely large amount of data.
What is the memory capacity of a 32-bit processor?
A 32-bit processor can access 4 gigabytes of information.
What is the memory capacity of a 64-bit processor?
A 64-bit processor can access up to 17 billion gigabytes of information.
How can you check the system type in Windows?
Go to the Control Panel under the System settings to see the system type.
What type of hardware drivers should you use for a 32-bit operating system?
Use 32-bit hardware drivers for a 32-bit operating system.
What type of hardware drivers should you use for a 64-bit operating system?
Use 64-bit hardware drivers for a 64-bit operating system.
What does x86 software refer to?
x86 software refers to 32-bit software, referencing the Intel 8086 processors.
What does x64 refer to?
x64 refers to 64-bit processors.
Can you run 64-bit applications on a 32-bit operating system?
No, you cannot run 64-bit applications on a 32-bit operating system.
Can you run 32-bit applications on a 64-bit operating system?
Yes, a 64-bit operating system can run both 64-bit and 32-bit applications.
Where are 32-bit applications installed on Windows?
32-bit applications are installed under Program Files (x86).
Where are 64-bit applications installed on Windows?
64-bit applications are installed under Program Files.
What is the ARM architecture?
The ARM architecture is developed by ARM Limited, known for efficiency and is commonly used in mobile devices.
How does ARM architecture compare to traditional 64-bit operating systems?
ARM architecture is expanding its capabilities, blurring lines with traditional 64-bit operating systems.
What does a CPU consist of?
A CPU consists of multiple cores, caches, memory controllers, and sometimes graphics processors.
What is the purpose of CPU caches?
Caches are designed to help speed the processing of information into and out of the CPU.
How does Hyper-Threading Technology (HTT) affect CPU performance?
HTT increases the throughput of processes by 15% to 30%, making a single physical CPU core appear as multiple cores.
How can you check if your CPU supports virtualization?
Check your BIOS for Intel Virtualization Technology (VT) or AMD Virtualization (AMD-V).
What is virtualization and why is it resource-intensive?
Virtualization allows running multiple operating systems on one computer. It is resource-intensive because it involves running multiple OS instances simultaneously.
