What happens when you click on a URL
What type of click?
There are multiple ways to click an item including Single-click, Double-click, Right-click, Click and drag and Click twice. In this article, I am talking about Single-click.
Browser, Operating System and URL
When you click on a link, the browser and operating system will figure out where you’ve clicked. The URL(Uniform resource locator) has hidden information associated and indicates the next web page that you want view.
A URL consists of five parts — the scheme, subdomain, top-level domain, second-level domain, and subdirectory.
“https://” — Scheme, tells web server which protocol to use.
“blog” — Subdomain, indicates which particular page of the website the browser should serve up.
“maeema” — Second level domain(SLD), the name of your website.
“.com” — Top level domain(TLD), specifies what type of entity your organization registers as on the internet.
“/stories/” — Subdirectory, helps people understand which particular section of a webpage they’re on.
DNS and TCP/IP
Domain Name System (DNS) maps URL to Internet Protocol (IP), and will get an IP address back for the site. The browser will opens a Transmission Control Protocol (TCP) connection to the web site over IP address. It asks to speak to Hypertext Transfer Protocol (HTTP) server, or HTTPS for secure connections.
HTTP and HTTPS are rules that are defined to send and receive data packets over the web. The client sends a request message to an HTTP/HTTPS server, which hosts a website, the server then responds with the response message, along with completion status information such as HTTP/1.1 200 OK.
Which then provides the web page in Hyper Markup Language(HTML) that your browser renders.
