FSD UNIT-1

## Introduction to Full Stack Development - **Definition**: Full stack development encompasses the complete development of applications, integrating both frontend and backend components. - **Frontend**: The user-facing part of the application accessible by clients. - **Backend**: Core functionality and business logic of the application, including data management. - **Skills Required**: Knowledge of various technologies, programming languages, and databases. ## Modern Application Architecture ### Structure - **3-Tier Architecture**: Consists of three layers, each serving a unique purpose. - **Presentation Layer**: User interface elements, focusing on design and navigation. - **Application Layer**: Contains business logic, processes user input, and executes business rules. - **Data Layer**: Manages persistent data storage and data retrieval. ### Importance of Separation - Separating these components improves efficiency, security, maintenance, and extensibility of applications. ## Technologies Related to Full Stack Development ### Frontend Development - **Definition**: Encompasses all elements visible to users, such as design and user interaction. - **Technologies Used**: - **HTML**: The foundation markup language for web structure. - **CSS**: Styling language for visual aspects of web applications. - **JavaScript**: Adds interactivity to web pages. - **Frameworks**: ReactJS, Angular for enhanced interactivity and development speed. ### Backend Development - **Definition**: Involves server-side coding, database management, and server setup. - **Technologies Used**: - **Languages**: Python, Ruby, PHP, and Node.js for server-side development. - **Database Management Systems**: MySQL, PostgreSQL, MongoDB for storing and accessing data. ## Full Stack Developer Skills - **Versatility**: Manages both frontend and backend tasks. - **Technologies**: Familiarity with HTML, CSS, JavaScript, PHP, MySQL, and additional tools to aid development. ## Frontend Technologies ### Key Components - **HTML**: Structuring web pages and applications. - **CSS**: Styling web elements for desired appearance. - **JavaScript**: Functionality and interactive elements in web applications. ### Libraries and Frameworks - **Bootstrap**: A toolkit for responsive design and mobile application development. - **JQuery**: Simplifies DOM manipulation and enhances web interaction. - **AngularJS and React.js**: Frameworks that facilitate the creation of dynamic web applications. ## Backend Technologies ### Key Languages and Frameworks - **Python**: High-level language, great for backend development, easy syntax. - **PHP**: Popular for server-side scripting, known for flexibility and ease of use. - **Node.js**: Enables JavaScript for server-side programming. ## Process of Full Stack Development ### Stages 1. **Planning and Design**: Requirements gathering and feature specification through collaboration with stakeholders. 2. **Frontend Development**: Setting up project structure and implementing UI/UX designs. 3. **Backend Development**: Coding for server-side logic, database integration, and ensuring data flows appropriately. 4. **Testing and Integration**: Comprehensive testing for functionality and bug detection before deployment. 5. **Deployment and Maintenance**: Monitoring application performance post-deployment and addressing any issues proactively. ## HTML5 New Elements ### Overview - **New Functionalities**: HTML5 introduces several new elements that enhance web design capabilities, making it easier to create dynamic and interactive sites. ### Key HTML5 Elements - **
