The World Wide Web (WWW) is a vast network of interconnected computer systems that enables communication and sharing of information across the globe. It is facilitated by a set of interconnected components: the HyperText Markup Language (HTML), the Uniform Resource Locator (URL), and the Domain Name System (DNS).
HTML is the building block of the web. It is a markup language that defines the structure and content of a web page. It consists of tags, which are enclosed by angle brackets, and contains data. For example:
Tag: <p>This is a paragraph.</p>
Content: "This is a paragraph."
URL is a standardized address that identifies a specific web page on the internet. It consists of three parts separated by dots:
Protocol: The protocol specifies the communication method, usually HTTP (HyperText Transfer Protocol).
Domain name: The domain name is the name of the website, like "google.com".
Path: The path specifies the specific location of the page within the website, like "/index.html".
DNS is a distributed system that translates human-readable domain names into machine-readable IP addresses. This allows computers to communicate with each other regardless of their location.
In summary:
The WWW is a network of interconnected computers.
HTML is the language that defines the structure and content of a web page.
URL is a standardized address that identifies a specific web page.
DNS translates human-readable domain names into machine-readable IP addresses.
This is a basic overview of the topic. There are many other aspects to learn about the World Wide Web, but this should give you a good understanding of the fundamental concepts involved
