Full-stack web development refers to the practice of developing both the front-end (client-side) and back-end (server-side) components of a web application. A full-stack developer is proficient in both the technologies and frameworks used for front-end development (such as HTML, CSS, and JavaScript) and those used for back-end development (such as databases, server-side languages, and web servers).

Front-End Development: Front-end development involves creating the user interface and user experience of a web application. This includes designing and coding the visual elements that users interact with, such as layouts, forms, buttons, and menus. Front-end developers use languages like HTML for markup, CSS for styling, and JavaScript for interactivity and dynamic behavior.

Back-End Development: Back-end development focuses on the server-side logic and database management of a web application. This includes writing server-side code to handle requests from clients, process data, interact with databases, and generate dynamic content
Databases: Databases are used to store and manage the data required by web applications.

APIs (Application Programming Interfaces): APIs are used to facilitate communication and data exchange between different components of a web application, as well as between the application and external services or systems.

Overall, full-stack web development requires a diverse skill set and a deep understanding of both front-end and back-end technologies. Full-stack developers are versatile professionals who can work on all aspects of web development, from designing user interfaces to managing server infrastructure, and they play a crucial role in bringing web applications to life.
