What is a Full Stack?

There are two main categories of processes involved in developing a software application: front-end development and back-end development.

Front-end development is all about the client’s side of the application. A front-end developer’s main goal is to make sure the end product looks attractive and is user-friendly in terms of navigation.

Back-end development handles the server side of the application. A back-end developer uses programming languages to exchange information between the browser and back-end databases.

Full-stack development involves developing both the front-end and back-end of a web application or website. A software stack is a collection of various components that work together to ensure the smooth functioning of an application. These components include:

• software products

• coding frameworks

• servers

• operating systems

• database tools

They are stacked on top of each other to enable user interaction, perform calculations, and support back-end functions. This complete collection of components is referred to as a “full stack.”
