How Does TCP connection walkthrough | Networking tutorial (13 of 13) Work?

Imagine you're sending a big bag of candy to your friend across town, but instead of just tossing it over the fence, you make sure every piece gets there safely and in order.

TCP connection walkthrough is like setting up a funny little delivery route between two friends (or computers), so they can send messages back and forth without losing any letters or getting confused about which one came first.

1. First, you knock on your friend's door, this is called handshaking, like saying “Hello! Are you ready to receive candy?”
2. Once they say yes, you start sending candies (data) in little boxes (packets), each with a number so your friend knows which one came first.
3. Your friend checks every box and sends back a message, acknowledgment, saying “Got it! Next one please!”
4. If any candy gets lost, you just send that one again, like when you shout “Did you get my letter?” if you don’t hear them reply.

This way, even if some candies are delayed or dropped, your friend still gets the whole bag, all in order, and you both have a great time sharing sweets!
