Imagine this:
You’ve got a friend named TCP. He’s a real gentleman. 👔
You send a message, “hey, what’s up?” and he replies,
“Got it, I’ll deliver it perfectly, every word, every punctuation mark.”
Yep, he’s Mr. Reliable. 📦📬
On the other side, you’ve got another buddy, UDP.
He’s a total speed junkie. 🏎️
You send, “hey, what’s up?”
He’s like, “Cool, I sent it. Did it arrive? Missing parts? Don’t care, bro. I’m fast, that’s all that matters.”
Basically, he’s the wild one. ⚡
📜 Who is TCP?
- Reliability king → Your message never gets lost.
- Connection-oriented → Knocks before entering: “Hi, I’m here.”
- Keeps order → Message 1, Message 2… all delivered in sequence, no mix-ups.
- But kinda slow → Because he’s a control freak.
Use cases: Websites 🌐, emails 📧, file downloads 📂
(Because nobody likes a half-downloaded file!)
📜 Who is UDP?
- Speed demon → No “better late than never,” just pure speed.
- Connectionless → Doesn’t knock, just bursts into the room. 🚪💨
- Doesn’t care about order → Message 1 arriving after Message 3? Meh.
- But lightweight & fast → No extra baggage.
Use cases: Online games 🎮, live streaming 📺, voice calls 📞
(Because speed matters more than perfection—no one cries over a missing second of video.)
