Question 2

In the classic top-level structure of a computer, which component performs arithmetic and logical decisions inside the CPU?

Accepted Answer

Arithmetic logic unit

Answer

Control unit

Answer

Output unit

Answer

Memory unit

Question 3

Why is studying computer architecture especially important for computing professionals?

Accepted Answer

It helps them understand performance trade-offs between hardware components and software behavior

Answer

It explains why high-level languages never need hardware support

Answer

It proves that software performance depends only on algorithm choice

Answer

It removes the need to learn operating systems or compilers

Question 4

Which operation is best described as data movement rather than storage or processing?

Accepted Answer

Keyboard input appearing on the screen

Answer

Updating a bank statement in memory

Answer

Internet download to disk

Answer

Sending processed records from storage to a printer

Question 5

What is the key idea of the stored-program principle associated with the Von Neumann model?

Accepted Answer

Instructions are stored in memory alongside data and fetched for execution

Answer

Programs must be permanently wired into the control unit

Answer

Only input devices may supply instructions to the CPU

Answer

Each arithmetic operation requires a separate processor core
