Backend
The backend is the part of a computer system, software, or website that stores and processes data, but is not directly used by the user.

- In a computer system
- In a website
- In application development
The backend is where data is stored or processed, rather than the parts that are seen and used by the user.
The backend is everything that happens behind the scenes, including the servers and databases. It's responsible for storing and organizing data, and ensuring that everything on the client-side works.
The backend is the data and infrastructure that make an application work. It stores and processes application data for users.
Back-end developers work on the server-side software of a website or mobile app. They focus on the databases, back-end logic, application programming interface (APIs), architecture, and servers. Back-end developers use code to help browsers communicate with databases, store, understand, and delete data.
Some popular backend frameworks include: Django for Python, Ruby on Rails for Ruby, Spring Boot for Java, and Gin for Go.
Python is a popular language for backend development because it's simple and easy to learn and use.
