1. *SYN (Synchronize):* Like saying "Hello?" to check if someone's there.
2. *SYN-ACK (Synchronize-Acknowledge):* The other person responds with "Hi, I'm here!"
3. *ACK (Acknowledge):* You confirm with "Great, let's talk!"

This three-way handshake ensures both parties are ready to communicate. According to [RFC 793](https://tools.ietf.org/html/rfc793), this process minimizes data loss, much like how a good conversation ensures both parties are on the same page.

But here's the kicker: TCP also has flow control. If one side is talking too fast (sending too much data), the other can say "Whoa, slow down!" (via window size adjustment). It's like asking someone to repeat themselves when they're speaking too quickly.

In 2022, TCP accounted for 90% of internet traffic, proving its reliability. So next time you're in a smooth conversation, thank TCP for setting the standard!
