Question 1

How many bytes can a computer with a 64-bit data bus transfer at one time?

Accepted Answer

A 64-bit data bus can transfer 8 bytes at one time, as there are 8 bits in a byte.

Question 2

Which of the following can be described as the description of a CPU's internal circuitry, the technology used to create the chip, and its supported instruction set?

Accepted Answer

Microarchitecture refers to the way a CPU's internal circuitry is designed, the technology used to manufacture the CPU, and the instruction set it supports. This includes how instructions are interpreted, the CPU's internal components, and how they interact.

Question 3

What are the numeric values created by an assembler that represent CPU machine instructions?

Accepted Answer

Opcodes are the numeric values created by an assembler that directly represent the instructions a CPU can execute. These are the machine-level codes that tell the processor what operation to perform.

Question 4

You are interested in seeing the assembly language instructions created when you write C++ code on your Windows 10 computer. What do you need to install on your computer to see the assembly language created by C++ code?

Accepted Answer

A compiler is necessary to translate C++ code into assembly language or machine code. The process involves compiling the high-level C++ code into a lower-level form that can be understood by the computer's processor.

Question 5

When a CPU is executing a program and the current instruction needs four bytes of data, where does the CPU first look for the needed data?

Accepted Answer

The CPU first looks for the needed data in the cache, as it is the fastest memory component that stores frequently accessed data to speed up the data retrieval process.
