Q31❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
Which rotation operation inserts the Carry Flag into the leftmost position (MSB), shifts all bits one position to the right, and copies the exiting rightmost bit (LSB) into the Carry Flag?
Q32❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
Which conditional jump instruction is taken if the last arithmetic operation produced a result in its destination with even parity (Parity Flag `PF = 1`)?
Q33❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
When an unsigned source operand is subtracted from a smaller unsigned destination operand (`CMP DEST, SRC`), a borrow is required. Which status flag will be set?
Q34❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
True or False: The x86 assembly instructions `SHR` (Shift Logical Right) and `SAL` (Shift Arithmetic Left) perform the same shift operation.
Q35❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
True or False: The `JA` (Jump if Above) instruction cannot trigger a jump after a `CMP` instruction if the unsigned destination operand is greater than the source operand.
Q36❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
The bit shift operation diagram `| 0 | --> | 1 | 1 | 0 | 1 | 0 | 0 | 0 | --> | C |` (inserting 0 into MSB from left, shifting bits right, and dropping LSB into Carry Flag) represents which instruction?
Q37❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
The bit shift operation diagram `| C | <-- | 1 | 1 | 0 | 1 | 0 | 0 | 0 | <-- | 0 |` (inserting 0 into LSB from right, shifting bits left, and dropping MSB into Carry Flag) represents which instruction?
Q38❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
Between the conditional jump mnemonics `JNE` (Jump if Not Equal) and `JNZ` (Jump if Not Zero), the functional difference exists only for the __________.
Q39❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
An instruction that, upon execution, unconditionally branches to a target address regardless of the state of any CPU flags is called a(n) __________.
Q40❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
When performing a comparison (`CMP DEST, SRC`), if the result of subtracting source from destination is zero, the Zero Flag is set (`ZF = 1`). What does this condition indicate?
