=== checks type + value → boolean ≠ number → false
- 4
- 5
- 6
- 10
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Start value = 0
-
Increment by +2 each time
Iterations:
-
1 → 2
-
2 → 4
-
3 → 6
-
4 → 8
-
5 → 10
-
After 5 iterations, value reaches 10 (limit).
-
It should not exceed 10, so we stop here.
-
Total iterations = 5.
- for loop
- while loop
- do-while loop
- if statement

Explanation
An if statement checks a condition and executes once if it is true.
It does not loop repeatedly, unlike for, while, or do-while loops.
It effectively stops after the first true condition is evaluated.
- 4
- 5
- 6
- 7

Explanation
- Initial value: x = 0
-
Loop runs while x < 5
Iterations:
-
1st: x = 0 + 2 = 2
-
2nd: x = 2 + 2 = 4
-
3rd: x = 4 + 2 = 6
-
Now x = 6, condition x < 5 becomes false, loop stops.
-
Final value printed is 6.
- System shutdown
- Turn firewall off
- Switch off power abruptly
- Implement load balancing or throttling
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Load balancing distributes incoming data across multiple systems to reduce overload.
Throttling limits the rate of incoming requests to keep the system stable.
These methods help prevent crashes while keeping services running.

- UDP
- FTP
- HTTP

Explanation
UDP (User Datagram Protocol) is a connectionless protocol.
It sends data without establishing a connection between sender and receiver.
UDP is faster but less reliable than TCP.
TCP is connection-oriented and ensures data delivery.

کون سا سیکیورٹی سسٹم صرف خطرات کا پتہ لگاتا ہے لیکن کوئی ایکشن نہیں لیتا؟
- Intrusion Detection System (IDS)
- Intrusion Prevention System (IPS)
- Antivirus with firewall
- Firewall
اس سوال کو وضاحت کے ساتھ پڑھیں

An IDS monitors network or system activities to detect potential threats.
It does not block or prevent attacks; it only alerts administrators.
An IPS (Intrusion Prevention System) can take action to stop threats.
Antivirus and firewalls actively block or remove malicious activity.
