Day 1 – Learn the basics
I was a client of https://htmlacademy.com and started from the basics.
I learned how it works when I type a website name into the address bar and the website loads.
How does it works?
- Imagine a website is a house where all the information you want to access lives.
- The IP address is like the exact address of the house: street, building, apartment number. Without it, the mail carrier can’t find the right house.
- When you type a website name (example.com), your computer looks into the internet’s phone book (DNS).
It translates the name (example.com) into the precise house address (IP address, like 93.184.216.34). - The browser acts like a mail carrier who travels to that address to pick up a letter (information from the website).
- The mail carrier knocks on the door and asks: “Hello, I’d like to get the main page information of this house!”
This is called an HTTP request. - The server is the homeowner. They check that the mail carrier has the correct request.Then, they prepare and hand over a letter with the requested information.
- The homeowner gives a letter filled with photos, text, and instructions (HTML, CSS, JavaScript).
- The mail carrier returns home (to your computer) and unpacks the letter.
The browser reads the instructions (HTML, CSS, JavaScript) and neatly displays the content on your screen.
To sum up:
🏠 Server → A house with information
📍 IP Address → The house’s address
📖 DNS → A phone book for finding the address
📬 Browser → A mail carrier delivering the request and retrieving the response
🚚 IP (Internet Protocol) → The GPS and address system guiding the carrier.
📦 TCP (Transmission Control Protocol) → The rules ensuring every page (packet) is delivered correctly, in order, and without loss.
📝 HTTP Request → An order for the letter
📄 HTML, CSS, JS → The content of the letter
💻 Browser Screen → The unpacked letter you can read
