To reach a website we usually type in the website address that’s unique that computers recognize it and able to connect you to the location of where it is. ICANN coordinates these unique identifiers across the web. This coordination is irreplaceable incredibly valuable for it is what makes the existence of global internet possible.



What is ICANN?

ICANN was born in 1998. It is a nonprofit organization of those who are present across the world and dedicated in maintenance and coordinating the spaces of the internet for secure and stable network operation. ICANN performs technical maintenance work of the Central internet Address pools and DNS root zone registries which who pursue IANA (Internet Assigned Numbers Authority) function contract. When you make a website and register a domain on the internet the fee you pay to the domain name registrar who pays a small fee to ICANN to register your domain as part of the domain registration process.

ICANN does not control what content goes on the internet for it does not regulate internet access or help to stop spam from occurring. The main objectives is to help keep web safe with development and enforcement of policy on the internet’s unique identifiers. ICANN plays a vital role in the expansion and revolution of the internet.

What are Domain Names?

DNS (Domain Name System) is a system designed to make the internet accessible to the public. Computers make up the internet using series of numbers called IP address. Each number correlates to a different device finding one another. DNS use letters converted from series of numbers and links a precise series of letters using the same method. Another advantage to this system is that domain names don’t have to be tied to one particular computer because the between domain and an IP address can changed very quickly. This change will be recognized by the entire internet due to the constantly updating DNS infrastructure. This makes the internet an extremely flexible system. Domains are made of two elements which includes what comes before and after the dot.

Examples such as “com”, “org”, or “net”, are known as a top-level domain or TDL. The part before the dot is likely to be the name of a company or organization which is the domain name that you register. This is used for websites, emails, and other convenient online functions of the internet.

HTML

HTML was invented by Tim Berners-Lee the inventor of the Web. He created the idea of an internet-based hypertext system, this means a text contains links to other text that viewers can access very quickly.

HTML stands for Hyper Text Markup Language it is a language one would use to tell a web browser how to make a page look like. This allows the users to create and structure sections, paragraphs, headings, links, and blockquotes for web pages and applications. HTML is not a programming language since it does not have the ability to create dynamic functionality. It makes it possible to organize and format documents for the process of creating a webpage

published the first version of HTML in 1991 with 18 HTML tags. Each new version of HTML came with new tags and attributes to the markup. The most current and the biggest upgrade was the introduction of HTML5 in 2014.

HTML works as documents that are files that end with a .html of .htm extension. The average website includes several different html pages such as standard home page, about page, contact pages all in separate HTML documents. Tags, also called elements have an opening and a closing that use the syntax.

CSS

Cascading Style Sheet or CSS is a “stylesheet” language that alters how your website elements look like. One can create the design, layout, font, and the colors of the content by embedding a CSS file to your HTML document. The CSS syntax consists of a selector and a declaration block. The selector is the HTML element that you will control. Declaration block will contain the property name and the value of the HTML element all separated by a colon and set of curly brackets. CSS comes through and specifies your document’s style—page layouts, colors, and fonts are all determined with CSS. Think of HTML as the foundation (every house has one), and CSS as the aesthetic choices.



Why we use HTML and CSS

HTML code ensures the proper formatting of text and images so that your Internet browser may display them as they are intended to look. Without HTML, a browser would not know how to display text as elements or load images or other elements.
