CPU FACTS EXAM QUESTIONS WITH 100% RATED
ANSWERS, GET A+
What must be matched when selecting a CPU? - You must match the CPU to the motherboard or
select a motherboard that supports the chosen CPU.
Who are the two main CPU manufacturers? - Intel and AMD are the two major producers of
processors for modern PCs.
Do both Intel and AMD processors support Windows? - Yes, both work in PC systems and
support Windows software.
How do Intel and AMD differ in market share and cost? - Intel has a larger market share, while
AMD processors generally cost less.
What is the main difference between 32-bit and 64-bit processors? - A 32-bit processor processes
32 bits at a time; a 64-bit processor processes 64 bits at a time.
What is the memory limit of a 32-bit processor? - A 32-bit processor is limited to accessing 4GB
of memory.
What is the theoretical memory limit of a 64-bit processor? - A 64-bit processor can theoretically
access up to 16 exabytes of memory.
Why can't we use the full 16 EB memory limit of a 64-bit processor? - Current hardware and
operating system limitations impose much lower practical limits.
What must be true for software to use 64-bit processing? - The operating system and applications
must be written for 64-bit CPUs.
What is a processor instruction set? - It identifies all the instructions (operations) that a processor
can perform.
, What instruction set do 32-bit processors use? - 32-bit processors use the IA-32 instruction set,
also known as x86.
What instruction set do Intel Itanium processors use? - Itanium processors use the IA-64
instruction set.
What instruction set do AMD64 and Intel 64 processors use? - They use the x86-64 instruction
set, also referred to as x64.
Can 32-bit applications run on 64-bit processors? - Yes, 32-bit apps can run using specific
methods depending on the processor architecture.
How do Itanium processors run 32-bit applications? - They use a software layer to translate
between IA-32 and IA-64.
How do x64 processors run 32-bit applications? - They execute both 32-bit and 64-bit
instructions directly in hardware.
Can a 32-bit operating system run on a 64-bit processor? - Yes, but it will not utilize the full 64-
bit capabilities.
Do applications generally perform better on 64-bit systems? - Yes, especially if they are 64-bit
applications.
Can 32-bit applications sometimes perform better on 64-bit systems? - Yes, in some cases 32-bit
applications may perform better on 64-bit hardware.
What is a multi-core processor? - A multi-core processor contains multiple processors within a
single chip.
