What are examples of TCP and UDP in real life?
Solution 1:
UDP: Anything where you don't care too much if you get all data always
- Tunneling/VPN (lost packets are ok - the tunneled protocol takes care of it)
- Media streaming (lost frames are ok)
- Games that don't care if you get every update
- Local broadcast mechanisms (same application running on different machines "discovering" each other)
TCP: Almost anything where you have to get all transmitted data
- Web
- SSH, FTP, telnet
- SMTP, sending mail
- IMAP/POP, receiving mail
EDIT: I'm not going to bother explaining the differences, since you state that you already know and every other answer explains it anyway :)
Solution 2:
UDP is mailing a letter at the post office.
TCP is mailing a letter with a return receipt at the post office, except that the post master will organize the letters in-order-of mailing and only deliver them in-order.
Well, it was an attempt anyway.
Solution 3:
TCP:
- World Wide Web(HTTP)
- E-mail (SMTP TCP)
- File Transfer Protocol (FTP)
- Secure Shell (SSH)
UDP:
- Domain Name System (DNS)
- Streaming media applications such as movies
- Online multiplayer games
- Voice over IP (VoIP)
- Trivial File Transfer Protocol (TFTP)
Solution 4:
REAL TIME APPLICATION FOR TCP:
Email:
Reason: suppose if some packet(words/statement) is missing we cannot understand the content.It should be reliable.
REAL TIME APPLICATION FOR UDP:
video streaming:
* **Reason: ***suppose if some packet(frame/sequence) is missing we can understand the content.Because video is collection of frames.For 1 second video there should be 25 frames(image).Even though we can understand some frames are missing due to our imagination skills. Thats why UDP is used for video streaming.
