CompTIA A+ Certification Core 1 (220-1101) - 32-Bit Versus 64-Bit Computing

The video tutorial discusses the importance of standards in hardware and software, focusing on X86 and X64 architectures. It explains the difference between 32-bit and 64-bit systems, highlighting the exponential increase in data handling capacity with 64-bit. The tutorial also covers the instruction set architectures, including X86, X86X64, and X64, and mentions Intel's IA32. It concludes by emphasizing the modern shift towards 64-bit systems due to better security, graphics, and overall performance.

What is the primary difference between X86 and X64 architectures?

• X86 is for mobile devices, X64 is for desktops

• X86 is faster than X64

• X86 handles 32-bit data, X64 handles 64-bit data

• X86 is used for gaming, X64 is not

How much more data can a 64-bit system handle compared to a 32-bit system?

• Four times as much

• Twice as much

• One billion times as much

• Four billion times as much

What does the acronym IA-32 stand for?

• Internet Architecture 32-bit

• Integrated Architecture 32-bit

• International Architecture 32-bit

• Intel Architecture 32-bit

Why is 64-bit preferred over 32-bit in modern systems?

• It is cheaper

• It offers better security and performance

• It is more compatible with older software

• It uses less power

Which of the following is true about modern PCs and applications?

• They are equally 32-bit and 64-bit

• They are mostly 64-bit

• They are mostly 32-bit

• They do not support 64-bit
