Introduction to Web Development and Ruby on Rails

Web development is the process of creating and maintaining websites and web applications that are accessible via the internet. It encompasses a wide range of tasks, including web design, content creation, client-side scripting, server-side scripting, network security configuration, and database management.

At its core, web development involves translating a concept or idea into a functional website or web application. This typically involves collaboration between various professionals, including web designers, developers, and content creators.

Web development can be broadly categorized into two main components: front-end development and back-end development. Front-end development focuses on the user interface and user experience, involving the creation of visually appealing and interactive elements that users interact with directly in their web browsers. This includes HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript.

On the other hand, back-end development involves building and maintaining the server-side logic and database interactions that power the website or web application. This includes programming languages such as Ruby, Python, PHP, and frameworks like Ruby on Rails, Django, Laravel, etc. Back-end developers handle tasks such as data storage, user authentication, and server configuration.

In addition to front-end and back-end development, web development also encompasses other aspects such as web accessibility, search engine optimization (SEO), and web security. Accessibility ensures that websites are usable by people of all abilities, while SEO helps improve a website's visibility on search engines. Web security involves protecting websites and web applications from malicious attacks and unauthorized access.

Overall, web development is a dynamic and ever-evolving field that plays a crucial role in shaping the digital landscape. It requires a combination of technical skills, creativity, and problem-solving abilities to create compelling and functional web experiences for users across the globe.

Introduction to Ruby on Rails

Ruby on Rails, often simply referred to as Rails, is a powerful and popular web application framework written in the Ruby programming language. It was created by David Heinemeier Hansson and first released in 2004 as an open-source project.

Rails follows the Model-View-Controller (MVC) architectural pattern, which separates the application logic into three interconnected components:

Model: Represents the data and business logic of the application. In Rails, models are typically used to interact with the database and encapsulate the behavior associated with the application's data.

View: Handles the presentation layer of the application. Views in Rails are responsible for generating HTML, XML, or other formats to be served to the user's web browser.

Controller: Acts as an intermediary between the model and the view. Controllers receive requests from the web browser, interact with the appropriate models to retrieve or manipulate data, and then render the corresponding views to generate a response.

One of the key principles of Ruby on Rails is convention over configuration, which means that Rails makes assumptions about the best way to structure and configure a web application, reducing the need for developers to write repetitive code and allowing them to focus on solving business
