Introduction to Web Development

Junior Science Teacher – JST Test Preparation | Computer Section

Introduction

In today’s digital world, websites play a very important role in communication, education, business, and information sharing. The process of creating and maintaining websites is called Web Development. In the Junior Science Teacher (JST) test conducted by SIBA Testing Services, basic concepts of web development may appear in the Computer section.

Web development includes designing websites, writing code, creating web pages, and maintaining online platforms. Every website on the internet—from educational blogs to social media platforms—is developed using web technologies.

For teachers and students, understanding web development is important because it explains how websites work and how information is shared online. Even many educational platforms and blogs are created using web development technologies.

Since you are creating educational content on your website for test preparation, knowledge of web development can also help in managing and improving online learning resources.

What is Web Development?

Web Development refers to the process of creating, designing, and maintaining websites and web applications that run on the internet.

It includes tasks such as:

• Designing web pages
• Writing code for websites
• Managing web servers
• Maintaining website content

What is a Website?

A website is a collection of web pages that are connected together and available on the internet.

Examples of popular websites include:

• Google
• YouTube
• Wikipedia

These websites provide different services such as searching information, watching videos, and learning online.

What is a Web Page?

A web page is a single page of a website that contains information such as text, images, videos, and links.

Web pages are written using special languages like HTML and are displayed through a web browser.

What is a Web Browser?

A web browser is a software application used to access and display websites on the internet.

Examples of web browsers include:

• Google Chrome
• Mozilla Firefox
• Microsoft Edge

Browsers allow users to view web pages, search for information, and interact with websites.

Types of Web Development

1. Front-End Development

Front-end development refers to the part of the website that users see and interact with. It focuses on the visual design and layout of a website.

Front-end developers use technologies such as:

• HTML (HyperText Markup Language)
• CSS (Cascading Style Sheets)
• JavaScript

These technologies help create attractive and interactive web pages.

2. Back-End Development

Back-end development refers to the server-side part of a website.

It deals with:

• Databases
• Server operations
• Application logic

Back-end developers use programming languages such as:

• PHP
• Python
• Java
• Node.js

The back-end ensures that the website works properly and processes user requests.

3. Full-Stack Development

Full-stack development refers to working on both the front-end and back-end parts of a website.

Full-stack developers are skilled in multiple technologies and can build complete web applications.

Important Web Technologies

HTML (HyperText Markup Language)

HTML is the basic language used to create web pages. It defines the structure of the content on a webpage.

HTML elements include:

• Headings
• Paragraphs
• Images
• Links

Every website uses HTML as its foundation.

CSS (Cascading Style Sheets)

CSS is used to design and style web pages.

It controls the appearance of elements such as:

• Colors
• Fonts
• Layouts
• Spacing

CSS makes websites visually attractive.

JavaScript

JavaScript is used to make websites interactive.

It allows features such as:

• Buttons
• Animations
• Dynamic content
• Form validation

Most modern websites use JavaScript for improved user experience.

Web Servers

A web server is a computer system that stores websites and delivers web pages to users when they request them.

When a user enters a website address in a browser, the request is sent to the web server, which then sends the webpage back to the browser.

Domain Name

A domain name is the address of a website on the internet.

Example: www.example.com

Domain names make it easier for users to find websites without remembering numerical IP addresses.

Web development plays a major role in modern digital communication. It allows individuals and organizations to:

• Share information globally
