What is Web Technology?

Web technology is a set of various tools, techniques and programming languages used to design, develop and maintain websites and web applications. It includes both frontend (client-side) and backend (server-side) development, which are used to create a dynamic and user-friendly website.

In today's time, web technology is used in all kinds of online platforms such as business websites, e-commerce portals, social media sites, and learning management systems. Without them, no website or web application can function properly.

What is Web?

The Web, also known as the World Wide Web (WWW), is a globally connected digital network through which we access webpages and resources available on the internet. These webpages are connected to each other through hyperlinks, which we can easily view using a web browser (such as Google Chrome, Mozilla Firefox, Safari).

Key Points Related to the Web

  • The Web is an information-sharing platform that connects computers around the world.
  • It is a medium to access HTML pages, multimedia content, and online services.

The Web is used daily for searching, communication, shopping, and education.

Definition of Web

The World Wide Web (WWW) is a digital platform that provides the facility to access webpages, multimedia content, and information through the internet.

How Does the Web Work?

  • The user enters a URL (Uniform Resource Locator) into the browser.
  • The browser sends that request to a web server.
  • The server sends back the page or data according to the URL.
  • The browser displays that data in a visual format, such as a website or web page.

Types of Web Technology

The structure of web technology is mainly divided into two parts: Frontend (Client-Side) and Backend (Server-Side).

In addition to these, there are some supporting technologies that make a website more powerful, secure, and user-friendly.

What do beginners learn from Web Technologies?

1. Frontend Development

In web development, the very first and important step for beginners is Frontend Development. This is the phase where beginners learn how to create a webpage, how to design a webpage, and how to run the webpage in a browser.

  • HTML (HyperText Markup Language): HTML defines the structure of any webpage. It is a markup language that logically arranges elements like headings, paragraphs, images, buttons, links, tables, and forms on a web page. Beginners learn to prepare the framework of a webpage through HTML.
  • CSS (Cascading Style Sheets): CSS is used to make HTML elements attractive and responsive. Simply put, it is used to design the webpage. Through CSS, colors, fonts, layout, spacing, and alignment of a webpage or website are controlled. With the help of CSS, a webpage is made responsive according to SEO and user experience for devices like mobile, tablet, and desktop.
  • JavaScript (Basics): JavaScript is a scripting language that adds interactivity to a webpage. Beginners learn to create features like form validation and verification, alerts, dropdown menus using JavaScript. They also learn how to handle events like what action to take on a button click, mouseover, or input field response.

2. Backend Development

After frontend, beginners move towards backend development where they learn the logic and data processing aspects.

  • PHP (Hypertext Preprocessor): PHP is a widely used server-side scripting language used to create dynamic and interactive websites. With the help of PHP, data is retrieved from the server and processed to display real-time content on webpages. When a user fills a form or clicks a button, PHP handles that input and generates an appropriate response from the server. In backend development, PHP is not limited to form processing only. Through it, beginners learn how to connect form data to the database, how to implement user login/logout systems, authentication, and personalization features using sessions and cookies.
  • Database: In backend development, the role of the database is very important because it securely stores all user information and the dynamic data of the website. Beginners learn how to create tables in the database and how to insert, retrieve, update, and delete data in it.
