Question:
Which protocol in the TCP/IP suite is responsible for breaking data into packets and reassembling them at the destination providing reliable, connection-oriented delivery?
Which protocol in the TCP/IP suite is responsible for breaking data into packets and reassembling them at the destination providing reliable, connection-oriented delivery?
Show Hint
TCP = Reliable + Ordered + Connection-oriented communication.
Updated On: May 20, 2026
- IP (Internet Protocol)
- TCP (Transmission Control Protocol)
- UDP (User Datagram Protocol)
- HTTP (Hypertext Transfer Protocol)

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
In TCP/IP architecture, different protocols perform different tasks:
• TCP → Reliable, connection-oriented communication
• IP → Addressing and routing
• UDP → Fast but unreliable communication
• HTTP → Application layer protocol
Step 1: Role of TCP TCP performs:
• Segmentation (breaking data into packets)
• Sequencing (ordering packets)
• Error detection and correction
• Acknowledgement and retransmission
Step 2: Analyze other options
• IP → only routes packets
• UDP → no reliability
• HTTP → application layer protocol \[ \therefore \text{Correct answer is (B)} \]
