=== 7.2.2 TCP (Reliable, Connection-Oriented) ===
TCP (Transmission Control Protocol) is like sending a very important package with a tracking number and signature confirmation. When you send data using TCP, it makes sure that:

* All the data arrives, even if it has to be sent again.
* The data arrives in the correct order.
* The sender gets a confirmation that the receiver got all the data.

It's like a phone call where you make sure the other person heard everything you said. If something is missing or mixed up, TCP will detect it and ask for it to be sent again. This makes TCP reliable and connection-oriented (it sets up a "connection" or conversation before sending data). It's used for things like web Browse, email, and file transfers, where you absolutely need all the information to arrive correctly.
