How internet works?

You will know how internet works step by step

Step 1: the web browser sends a request

The initial process is to confirm the URL. Once the address is done with proper verification, the web browser will use few processes. It will just initiate by seeing up which procedure it will utilize. If the URL begins by http:// it will make use of the HTTP procedure, if it begins with ftp://, the web browser will make use the FTP protocol. It will then start searching where the web server is set. For this it needs to use next service of the Net: the DNS (Domain Name Server).

The DNS are servers that can getconnect a domain name (dlink router login page for example) to an IP address (216.239.39.101). It justas yellow pages that will link a name to a phone number. This IP address is unique and thus the server web is fastidentified. It is the IP address that your web browser will get in touch and will connect with the HTTP or FTP server. The request will have purpose at obtaining the index.html page.

Step 2: the web server takes back the info

The web server has obtained a request from a device that wants to get the index.html file. It will then search the index.html file on its hard drive, let take isdemonstration and the information it grasps, to lastly send the entire to the web browser. The web server distinguishes where to send the information because as you're on the internet you also get a unique IP address.

Step 3: the web browser processes the files

The web browser obtains the text of the index.html file. As the extension is .html, it will be managed as a HTML file. Firstly, the navigator doesn't get the iconographic content of the page. Therefore, it is mandatory, before viewing the page, collect all the images that are arrested in the file. Obviously these entire requests are entirelyobvious to you. Once all the basics are collected the page content will seem on your screen within few seconds.
