Earlier I explained functions of TCP/IPadvantages of UDP over TCP, and advantages of TCP over UDP. Find here the real life uses of both TCP and UDP.

Example Uses of TCP Protocol:

  • Internet (HTTP)
  • Secure Shell (SSH)
  • Email (SMTP/IMAP/POP)
  • File transfer (FTP)
  • Internet banking
  • Remote access to network devices
  • SMS

Uses of UDP protocol:

  • Audio and video streaming
  • Voice over IP (VoIP)
  • Online gaming
  • Trivial File Transfer Protocol (TFTP)
  • Domain Name System (DNS)
  • Radio (AM)
  • WiFi
  • Video conference

These were the real life uses of UDP and TCP. There may be more uses of TCP and UDP, but with the examples above, I hope you now have understood the role of TCP and UDP well.
