These are my notes taken while learning how the internet works. Here I have left everything that is essential for a software development student who wants to learn the internet concepts and applications necessary for web development. The topics of these notes are:
- What is a network and how does it work?
- How is data sent to another device outside the local network?
- What protection does the internet and other types of networks have?
- How is communication on the internet organized?
- What are the layers of communication over the internet?
- What are protocols and why do we need them?
- What is the OSI model and TCP/IP model?
- Detailed guide (with everything you need to know) about each layer of the practical model (TCP/IP).
- Detailed guide (with everything you need to know) to the main protocols present in each layer.
