Let's do it, let's first learn the basics of networking.

Before you start.

• Remember that notes are important.
• If you don't understand something feel free to google it and try to understand it.

Networking

This is a THM room, that will explain some basic concepts about networks.

Here is the link : Networking

After you finished

Networking Concepts

In this section we'll cover some important Networking concepts that are worth to understand. This will allow you to understand how networks work and how data goes through the network.

Before you start

• Notes!
• Occasionally review your notes, this will help you to remember and memorize.
• Try to understand everything, research somewhere else if something is not clear.
• Theoretical concepts are just as important as practice.

OSI Model

The first thing you should now is the OSI Model and how it works. You'll find what you need in here: OSI Model

TCP/IP Model

Then lets go to the next model: TCP/IP Model

TCP vs UDP

Now let's undestand the protocols: TCP vs UDP

IP address

Now your IP address: What is an IP address?

Now find your ip address: How to find your IP address in Linux

HTTP

Finally the HTTP and requests: What is HTTP?

Using CURL to do HTTP requests:: The curl guide to HTTP requests

After you finished

Now at this point you already know:

• What does each OSI model layer do.
• What does each TCP/IP model layer do.
• Which is the main protocol used in all Internet operations.
• How does TCP work.
• How does UDP work.
• When using TCP.
• When using UDP.
• Difference between UDP and TCP.
• What is an IP address.
• How to display your IP address.
• What is HTTP protocol and how it works.
• What is curl.
• The parts of an HTTP request.
• How to send GET and POST requests.
