Web Development Explained: A Beginner's Guide

Web development is the process of creating and maintaining websites and web applications that run on the Internet. A website is a collection of static pages that you can visit using a web browser while a web application is a dynamic, interactive platform that performs specific functions and tasks. It's a diverse field that involves a wide range of skills and technologies, which are generally divided into front-end, back-end, and full-stack development.

Think of a website like a house. The front end is the visible part – the paint, the furniture, and the layout. The back-end is like the foundation, plumbing, and electrical systems – essential but hidden. Full-stack developers are like architects and builders who can handle everything.

Front-end development, also known as client-side development, focuses on what users see and interact with directly. It's about crafting the user interface (UI) and user experience (UX). Key technologies include:

HTML (HyperText Markup Language): The foundation of web pages, defining the structure and content. Think of it as the skeleton.
CSS (Cascading Style Sheets): Styles the visual presentation, controlling layout, colours, fonts, and overall aesthetics. This is the skin and clothing.
JavaScript: Adds interactivity and dynamic behaviour, enabling animations, form validation, and user event handling. It's the muscles and nervous system. Frameworks like React, Angular, and Vue.js are frequently used for complex applications.

Back-end development, or server-side development, handles the behind-the-scenes functionality. It involves:

Server-side Languages: Languages like Python, Java, PHP, Node.js, Ruby, and Go process data and manage server logic.
Databases: Databases store and retrieve information. Think of them as digital filing cabinets. There are two main types:

Relational Databases (SQL): These organize data into tables with rows and columns, like a spreadsheet. They're great for structured data like customer information, product catalogues, or financial records. Examples include MySQL and PostgreSQL. Imagine a perfectly organized filing cabinet with labelled folders and everything in its place.
NoSQL Databases: These are more flexible and can handle unstructured or semi-structured data like social media posts, photos, or videos. They use different ways to organize information, like documents or key-value pairs. They're ideal when you have lots of different kinds of data that don't fit neatly into tables. Think of a big box where you can put all sorts of things without strict rules.

Servers: Servers host the application and make it accessible. Servers act as the homes where websites and web applications live. They store all the important information and make sure that when you type in a web address, the website shows up on your screen. Without servers, websites wouldn't be able to exist on the internet.

APIs (Application Programming Interfaces): Enable communication between different software systems, allowing the front end to interact with the back end. Imagine you're travelling to a country where you don't speak the language. An interpreter helps you communicate with the locals. Similarly, APIs help different software systems talk to each other and exchange information

Full-stack development combines both front-end and back-end expertise. Full-stack developers can handle all aspects of a project.

The web development process typically involves:

Planning: Defining project goals and requirements.
Design: Creating wireframes and mockups.
Development: Writing the code.
Testing: Identifying and fixing bugs.
Deployment: Making the application live.
Maintenance: Ongoing updates and improvements.
