How Web Works?

What is Web?

The World Wide Web (also known as the "web") is a global network of interconnected documents and other resources, linked by hyperlinks and URLs. It is a platform that allows people to access and share information, communicate with one another, and conduct business online.

The web is built on top of the Internet, which is a global network of computers that are connected to each other and can communicate with one another. The Internet allows computers to send and receive data, such as emails, files, and web pages, to and from one another.

The web was invented in 1989 by Tim Berners-Lee, a computer scientist working at CERN, the European Organization for Nuclear Research. He developed a system called the World Wide Web, which allowed scientists at CERN to share and access information easily. Today, the web is used by billions of people around the world for a wide range of purposes, including communication, education, entertainment, and commerce.

To access the web, you need a device that is connected to the Internet, such as a computer, smartphone, or tablet. You also need a web browser, which is a software program that allows you to view and interact with web pages and other resources on the web. Some examples of popular web browsers include Google Chrome, Mozilla Firefox, and Safari.

Defining Technical terms for Web

Here are some technical terms related to the web −

HTML (Hypertext Markup Language) - A programming language used to create and structure content on the web. HTML uses tags to mark up text, images, and other content, which can then be displayed in a web browser.

CSS (Cascading Style Sheets) - A programming language used to control the appearance of web pages and applications.CSS is used to style HTML elements, such as colors, fonts, and layout.

JavaScript - A programming language used to add interactivity and dynamic behavior to web pages and applications. JavaScript can be used to create effects such as animations, form validation, and event handling.

HTTP (Hypertext Transfer Protocol) - A protocol used to transfer data, such as web pages, between a server and a client. HTTP is the foundation of data communication on the web.

URL (Uniform Resource Locator) - A unique address that identifies a specific resource on the web, such as a web page or image. URLs typically start with "http −//" or "https −//" and are typed into a web browser's address bar to access a specific web page.

Web server - A computer that stores and serves web pages and other resources to clients over the Internet. Web servers are responsible for hosting and delivering content on the web.

Web client - A device or software program that sends requests for web resources to a web server and displays the results. Web clients include web browsers, such as Google Chrome or Mozilla Firefox, as well as other types of software programs that access the web, such as search engines and mobile apps.

Web page - A document or resource that can be accessed on the web using a web browser. Web pages are typically written in HTML and can include text, images, videos, and other types of media.

Web application - A software program that is accessed through a web browser and runs on a web server. Web applications can provide a wide range of functionality, from simple tasks like sending email to more complex tasks like managing a database.

How the web works?

The web works by using a combination of technologies, including the Internet, web servers, web clients, and web browsers. Here's a basic overview of how the web works −

A user opens a web browser on their device and types in a URL, or clicks on a link to a web page.

The web browser sends a request for the web page to the appropriate web server using the Hypertext Transfer Protocol (HTTP).

The web server receives the request and responds by sending the web page back to the web browser. The web page is typically written in HTML (Hypertext Markup Language) and may include other resources, such as images, videos, and style sheets written in CSS (Cascading Style Sheets).

The web browser receives the web page and renders it for the user to view. The web browser also runs any JavaScript code included in the web page, which may add interactivity or other dynamic behavior.

The user can interact with the web page by clicking on links, filling out forms, or performing other actions. These actions may trigger additional requests to the web server, which the server responds to in the same way as the initial request.

This process happens quickly and seamlessly, allowing users to access and interact with web pages and applications in real-time. The web is a global network of interconnected resources, and this process allows users to access and share information and resources with one another from anywhere in the world.
