Q61❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
After the execution of a Shift Arithmetic Right (`SAR`) instruction on a signed binary operand, what happens to the Most Significant Bit (MSB / sign bit)?
Q62❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
Unlike a short or near jump which is position-relative to the current Instruction Pointer (`IP`), a far jump instruction is __________ because it explicitly specifies both segment and offset target addresses.
Q63📝 Short Q📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
Briefly describe what the following assembly code sequence accomplishes in a single line:
`mov cx, 0xffff`

Q64❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
The bit diagram `| 0 | --> | 1 | 1 | 0 | 1 | 0 | 0 | 0 | --> | C |` illustrates which right-shift operation where 0 enters the MSB and the LSB is shifted into the Carry Flag?
Q65❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
The bit diagram `| C | <-- | 1 | 1 | 0 | 1 | 0 | 0 | 0 | <-- | 0 |` illustrates which left-shift operation where 0 enters the LSB and the MSB is shifted into the Carry Flag?
Q66❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
Since `JNE` (Jump if Not Equal) and `JNZ` (Jump if Not Zero) assemble into the exact same machine opcode (`0x75`), the distinction between these two mnemonics exists strictly for __________.
Q67❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
An instruction that upon execution transfers control unconditionally to a target address regardless of processor flags is called a(n) __________.
Q68❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
When comparing two numbers (`CMP DEST, SRC`), if subtracting the source from the destination yields zero, the Zero Flag is set (`ZF = 1`). This indicates that __________.
Q69❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
When an unsigned source operand is subtracted from an unsigned destination operand (`CMP DEST, SRC`) and the destination is smaller (`DEST < SRC`), a borrow occurs, which sets the __________.
Q70❓ MCQ📑 Lec 6Easy🔁Repeated⭐High-Yield💡Conceptual
In unsigned comparison (`CMP DEST, SRC`), if the result produces `ZF = 1` OR `CF = 1`, which relationship condition between unsigned destination (`UDEST`) and unsigned source (`USRC`) is satisfied?
