While watching a live cricket match online, you’re fully into the excitement — the commentary, the crowd noise, every ball bowled.
But suddenly your internet fluctuates.
The video quality starts dropping…
The screen even freezes for half a second…
and then continues.
The lost part of the video is gone, and you continue watching the match in real time. Why
Because live cricket match streaming uses UDP, a protocol designed for speed rather than perfection.
UDP doesn’t wait to fix lost data — it just keeps sending new packets so that your live match stays “live.”
You click Download, and the file starts saving to your device.
If your internet fluctuates, the download doesn’t get corrupted.
The document, when downloaded, is 100% complete, with no missing words. Why?
Because Google Drive uses TCP.
“If any piece of data is lost, I will bring it back — perfection matters more than speed for me.”
“If a piece of data is lost, I won’t go back. I’ll keep moving — speed matters more than perfection for me.”
TCP (Transmission Control Protocol) is a connection-oriented protocol, meaning it creates a reliable connection before sending data.
Think of TCP like sending a courier with tracking. Every packet is confirmed, tracked, resent if lost, and delivered in order.
UDP (User Datagram Protocol) is a connectionless protocol. It sends data without confirming if the receiver got it or not.
Think of UDP like shouting across a room.
If someone hears it, great. If they don’t—no retry.
| Feature | TCP | UDP |
| Connection | Connection-oriented | Connectionless |
| Speed | Slower | Faster |
| Reliability | High | Low |
| Acknowledge | Packets are acknowledged and Lost Packets are re-transmitted | Packets are not re-transmitted and not acknowledged |
In short: TCP = Reliability UDP = Speed
UDP is faster because it has no handshake, no acknowledgement
UDP is used because real-time speed is important in video calls
Because it uses acknowledgements of data and retransmissions of lost data
Below are some of the applications using TCP and UDP
TCP: http, https, smtp
UDP: DNS, Video calls, Live streaming, Online gaming, Online Meeting
Yes. They work independently and can run together whenever they want.
