What is TCP/UDP? Give me an example of each

TCP (Transmission Control Protocol)

  • Connection-oriented: Establishes a connection before data transfer.

  • Reliable: Guarantees delivery, order, and error-checking of data.

  • Slower: Due to overhead from connection setup, acknowledgments, and retransmissions.

  • Use cases: Web browsing (HTTP/HTTPS), email (SMTP), file transfers (FTP).

UDP (User Datagram Protocol)

  • Connectionless: No need to establish a connection before sending data.

  • Unreliable: No guarantee of delivery, order, or error correction.

  • Faster: Minimal overhead, suitable for real-time or loss-tolerant applications.

  • Use cases: Streaming (video/audio), online gaming, DNS queries, VoIP.
