[A] To make the pipeline faster

[B] Increase RAM

[C] Format hard disk

[D] Turn off monitor

सही उत्तर: Pipeline को अधिक तेज़ बनाना

व्याख्या: Branch Prediction CPU में पहले से अनुमान लगाकर instruction flow को तेज़ करता है ताकि pipeline stall न हो।

Correct Answer: To make the pipeline faster

Explanation: Branch prediction improves CPU performance by reducing pipeline stalls.

313. Static Branch Prediction किस पर आधारित होती है?

[A] Fixed Rules या Compiler Logic पर

[B] Real-time AI Analysis पर

[C] GPU Processing पर

[D] Cache Memory पर

313. Static branch prediction is based on?

[A] Fixed rules or compiler logic

[B] Real-time AI analysis

[C] GPU processing

[D] Cache memory

सही उत्तर: Fixed Rules या Compiler Logic पर

व्याख्या: Static prediction पहले से तय नियमों पर आधारित होती है, runtime behavior पर नहीं।

Correct Answer: Fixed rules or compiler logic

Explanation: Static branch prediction uses predefined rules instead of runtime behavior.

314. Dynamic Branch Prediction किसका उपयोग करती है?

[A] Runtime History Data

[B] Hard Disk Data

[C] Monitor Data

[D] Keyboard Input

314. Dynamic branch prediction uses?

[A] Runtime history data

[B] Hard disk data

[C] Monitor data

[D] Keyboard input

सही उत्तर: Runtime History Data

व्याख्या: Dynamic prediction पिछले execution history का उपयोग करके सही branch का अनुमान लगाती है।

Correct Answer: Runtime history data

Explanation: Dynamic prediction uses past execution history to predict branches.

315. Branch Target Buffer (BTB) का कार्य क्या है?

[A] Branch Address को Store करना

[B] RAM बढ़ाना

[C] CPU Cooling करना

[D] Monitor Control करना

315. What is the function of Branch Target Buffer (BTB)?

[A] Store branch addresses

[B] Increase RAM

[C] Cool CPU

[D] Control monitor

सही उत्तर: Branch Address को Store करना

व्याख्या: BTB branch instructions के target addresses को store करता है ताकि execution तेज़ हो।

Correct Answer: Store branch addresses

Explanation: BTB stores target addresses of branch instructions for faster execution.

316. CPU में Speculative Execution क्या है?

[A] Possible Instructions को पहले से Execute करना

[B] RAM Format करना

[C] Hard Disk Delete करना

[D] Monitor बंद करना

316. What is speculative execution in CPU?

[A] Executing possible instructions in advance

[B] Formatting RAM

[C] Deleting hard disk

[D] Turning off monitor

सही उत्तर: Possible Instructions को पहले से Execute करना

व्याख्या: Speculative Execution में CPU अनुमानित instructions को पहले से execute करता है।

Correct Answer: Executing possible instructions in advance

Explanation: Speculative execution runs instructions before branch outcome is confirmed.

317. Out-of-Order Execution का मुख्य लाभ क्या है?

[A] Idle CPU Cycles को कम करना

[B] RAM बढ़ाना

[C] Hard Disk Speed बढ़ाना

[D] Change monitor

सही उत्तर: Idle CPU Cycles को कम करना

व्याख्या: Out-of-Order Execution CPU को ready instructions पहले execute करने देता है जिससे efficiency बढ़ती है।

Correct Answer: Reduce idle CPU cycles

Explanation: Out-of-order execution improves CPU utilization by executing ready instructions first.

318. In-Order Execution क्या दर्शाता है?

[A] Instructions का क्रम में निष्पादन
