Understanding the Web by Udemie
What happens when you read a webpage on a web browser on your computer or phone can be simplified by understanding how the web works. While this theory isn’t necessary to write web code, knowing what’s going on behind the scenes will be quite helpful in the long run.
Understanding the Web Synopsis
Clients and Servers (Users and Hosts)
Clients and servers are computers linked to the internet. Clients can access resources and services from a central computer via a client-server network. For example, web browsers act as clients, sending HTTP requests to servers to get resources such as images, audio, text, and fonts. They also create a Document Object Model (DOM) and render the page to the user.
Let’s say you are a Facebook user with an account. Whenever you visit https://facebook.com on your web browser (Chrome, Firefox, Internet Explorer, etc.), your browser (client) sends a request to Facebook’s server to get the home page of the address. The server sends back an HTTP response to the client. The response contains an HTML file that represents the home page of the website (Facebook). The browser converts the HTML file to a DOM and displays/renders the home page.
