Computer Architecture, Memory, and
Cyber Security Fundamentals Exam
Questions & Answers (Grade A+)
What is the purpose of a translator in programming? -
correct answer ✅To convert source code from high-level languages
into machine code.
What is the difference between a compiler and an interpreter? -
correct answer ✅A compiler translates the entire program into
machine code before execution, while an interpreter translates
code instruction by instruction.
What components make up the Von Neumann architecture? -
correct answer ✅Control Unit (CU), Arithmetic and Logic Unit
(ALU), Memory Unit (typically RAM), Inputs and Outputs.
What is the role of the CPU? -
correct answer ✅To fetch, decode, and execute instructions.
What does the Control Unit (CU) do? -
correct answer ✅Sends signals to control how data moves around
the CPU.

Cyber Security Fundamentals Exam
Questions & Answers (Grade A+)
What is the function of the Arithmetic Logic Unit (ALU)? -
correct answer ✅Performs calculations and logical decisions.
What is cache memory? -
correct answer ✅A temporary storage that provides fast access to
frequently used instructions and data.
How does clock speed affect CPU performance? -
correct answer ✅It measures the number of cycles per second,
affecting how quickly the CPU can process instructions.
What is the difference between RAM and ROM? -
correct answer ✅RAM is volatile and used for temporary storage
while the computer is running, whereas ROM is non-volatile and
stores permanent instructions.
What is an embedded system? -
correct answer ✅A computer system with a dedicated function
within a larger mechanical system.
