ہماری مدد کریں
اگر آپنے پیپر دیا ہے یا دیں گے تو جو سوالات پیپر دنیے کے
بعد اپکو یاد ہیں پلیز ہمارےساتھ شئیر
کریں بے شک 5 سے 10 ہی کیوں نہ ہوں۔
تاکہ اگلی بار
جب پیپر ہو تو دوسرے لوگوں کو اس میں مدد مل سکے۔ کیونکہ بہت سے لوگوں کو پیپر
پیٹرن سلیبس وپیپر میں سوالات کس طرح کے آسکتے معلوم نہیں ہوتا۔ پاسٹ پیپرز سے
بہت سی معلومات و کنسپٹ کلئیر ہو جاتے۔ اس کام میں پلیز ہماری مدد کریں۔ جزاک اللہ
نوٹ کسی بھی طریقہ سے پیپر کو لیک
کرنا، تصویر بنانا قانو جرم وحرام کام ہے۔
ہم صرف ان سوالات کو شئیرکرنے کی بات کر رہے جو پیپر دینے کے بعد آپکوزبانی
یاد راہ جائیں۔ اللہ آپ کو کامیاب کرے آمیں۔

Image classification
Object detection
Image filtering
Edge enhancement
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Image classification assigns each pixel or regio n in an image to a specific category .
In satellite imagery, categories could i nclude roads, mountains, and houses .
Object detection identifies objects and their locations but may not label all pixels.
Image filtering and edge enhancement improve image quality but don’t classify content.
Higher true positives
Lower true positives
Higher false positives
No effect on model performance
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
False negatives (FN) occur when the model misses positive cases .
Reducing FN usually means the model is more likely to predict positive .
This increases true positives (TP) b ut also can increase false positives (FP) .
To write code faster
To provide guidance for users and developers
To compile the program
To secure software
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Software documentation explains how a program works and how to use it.
It helps developers understand the code for maintenance or updates.
It guides end-users on using software features effectively.
Agile
Waterfall
Spiral
Incremental
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The Waterfall model is a sequential SDLC approach. Each phase (requirements, design, implementation, testing, deployment) is completed before the next begins. It works best when requirements are clear and unlikely to change. Agile and Incremental models are better for changing or evolving requirements . Spiral focuses on risk management and iterative development.
RSA
AES
SHA-256
Diffie-Hellman
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
AES (Advanced Encryption Standard) is a symmetric encryption algorithm. Symmetric encryption uses the same key for encryption and decryption . RSA and Diffie-Hellman are asymmetric algorithms using public/private keys. SHA-256 is a hash function, not an encryption algorithm.
Confidentiality
Integrity
Availability
Authentication
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Integrity ensures that data is accurate and unaltered .
It protects against unauthorized modifications or tampering .
Undefined
Empty string ("")
[]
0
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
In JavaScript, the + operator performs string concatenation if any operand is a string.
[] (an empty array) is converted to an empty string when used with +.
So [] + [] become s "" + "" → "" (empty string).
This is due to type coercion in JavaScript.
The result is not undefined, [], or 0—it’s an empty string.
'hello'
Undefined
['h', 'e', 'l', 'l', 'o']
'lo'
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The spread operator ... in JavaScript expands iterable objects like strings or arrays.
"hello" is a string, which is iterable.
[..."hello"] spreads each character into a new array.
Resulting array: ['h', 'e', 'l', 'l', 'o'].
It is not a single string or 'lo', and definitely not undefined.
Program runs successfully
Compile-time syntax error
Undefined reference (linker error)
Infinite loop
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The extern keyword declares a function without providing its definition.
display() is called in main, but the compiler cannot find its actual implementation.
Compilation passes the syntax check, but linking fails.
The linker reports an undefined reference error.
Default values are not allowed in functions
Default parameters must be declared from right to left
Parameters must be initialized to zero
Function syntax is invalid
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
In C++, default arguments must be assigned from right to left .
If a parameter has a default value, all parameters to its right must also have defaults .
The rule ensure s unambiguous function calls .
