TCP/UDP

• UDP is used when speed is more important than perfection. It sends data quickly without checking if every single piece gets there, so it’s ideal for things like:

  • Live streaming (like watching videos in real-time)

  • Online gaming (where quick response is key)

  • Voice and video calls (where a little lag is okay as long as it stays smooth)

​UDP (User Datagram Protocol)

• TCP/IP is mainly used when you need reliable and accurate communication. It makes sure all the data arrives in order and without any mistakes. This makes it perfect for things like:

  • Browsing websites

  • Sending emails

  • Downloading files
