A framework is a collection of tools, libraries, and rules that help software developers build applications more quickly, efficiently, and with higher quality. Frameworks provide a pre-defined structure and standards for software development, allowing developers to focus on the unique features and logic of their applications rather than starting from scratch.

Key features of a framework include:

1. Pre-defined structure: Frameworks offer a ready-made framework for organizing code and project files, guiding developers along the right path.
2. Built-in tools and libraries: Many frameworks come with tools and libraries that simplify common tasks like data management, database interaction, authentication, and request handling.
3. Faster development: With a framework, a significant portion of the coding is already done, which greatly speeds up the development process.
4. Standardization: Frameworks promote coding standards, making projects easier to manage, maintain, and ensuring that code is more organized and understandable.
5. Security features: Many frameworks have built-in security features that help protect applications from common attacks.

Overall, frameworks allow developers to create complex applications with less code, while also improving the quality, security, and maintainability of the project.
