None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Polymorphism allows objects to be treated as instances of their parent class. This enabling them to take on different forms (e.g., method overriding or overloading). It promotes flexibility and reusability in object-oriented programming.
ہیش ٹیبل میں تلاش کرنے کی وقت کی پیچیدگی کیا ہے؟
O(1)
O(N)
O(log N)
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
On average, searching in a well-implemented hash table has a time complexity of O(1) (constant time) due to direct indexing using the hash function.
In the worst-case scenario , if many elements hash to the same index (collisions), the time complexity can degrade to O(n) (linear time).
کس قسم کے نیٹ ورک اٹیک میں صارف کی حساس معلومات کا انکشاف کرنا شامل ہے؟
Denial of Service (DoS)

0(N²)
O(N)
O(log N)
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
In a nested for-loop , the inner loop executes N times for each iteration of the outer loop.
This results in a total of N × N = N² iterations, making the time complexity O(N²).

Solid State Drive (SSD)
Hard Disk Drive (HDD)
Optical Disk Drive (ODD)
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
SSDs have no moving parts, which results in faster data access speeds and lower latency .
HDDs rely on mechanical components like spinning disks , which make them slower and more prone to delays in data retrieval.

5
10
8
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A base-5 number system uses digits from 0 to 4 , meaning there are 5 different digits in total.
Any number system in base-N uses N unique digits , so base 5 has 5 digits (0, 1, 2, 3, 4) .
