One of the main ones is the Transmission Control Protocol (TCP). This protocol ensures that data sent from one computer to another arrives safely and in the correct order. It breaks large pieces of data into smaller parts, sends them, and then puts them back together at the other end. This is helpful for things like web browsing and email, where missing or out-of-order data would be a problem.

Another important protocol is the Internet Protocol (IP). This one is responsible for sending data to the right place. Every device on a network has a unique IP address, and the Internet Protocol uses that address to figure out where to send information. It’s kind of like writing an address on a letter to make sure it gets to the right house.

A third key protocol is the Hypertext Transfer Protocol (HTTP). This is used when you visit websites. It tells your browser how to ask for web pages and how the web server should respond. Without HTTP, we wouldn’t be able to view or interact with websites like we do every day. These three protocols work together to make online communication possible
