Q37❓ MCQ📑 Lec 3Easy🔁Repeated⭐High-Yield💡Conceptual

What is the standard file extension for assembly language source code files?

Q38❓ MCQ📑 Lec 3Easy🔁Repeated⭐High-Yield💡Conceptual

True or False: In x86 assembly language, Register-to-Register operations (e.g., `mov ax, bx` or `add ax, bx`) are not allowed.

💻 assembly Snippet

mov ax, bx ; Fast register-to-register data transfer

Q39❓ MCQ📑 Lec 3Easy🔁Repeated⭐High-Yield💡Conceptual

In x86 assembly language architecture, the general-purpose register `CX` is primarily used as a __________.

💻 assembly Snippet

mov cx, 10
loop_start:
    ; loop body
    loop loop_start ; Decrements CX and jumps if CX != 0

Q40❓ MCQ📑 Lec 3Easy🔁Repeated⭐High-Yield💡Conceptual

True or False: Executing the data movement instruction `mov ax, 0` will set the Zero Flag (`ZF = 1`).

💻 assembly Snippet

mov ax, 0 ; AX becomes 0, but FLAGS register is unchanged
