The purpose of a feature branch in Gitflow is to isolate the development of a new feature. It allows developers to work on a specific feature without affecting the main branch until the feature is complete and ready for integration.

The process of verifying the identity of a user or system is known as authentication. It ensures that the entity trying to access a system is who it claims to be. The correct option corresponds to the authentication process.

Query optimization in databases refers to the process of improving the efficiency of database queries. It involves choosing the most efficient means of executing a SQL query to minimize response time and resource usage.

The main difference between Docker and Kubernetes lies in their primary roles. Docker is primarily a containerization platform, allowing you to package and distribute applications. Kubernetes, on the other hand, is a container orchestration platform, managing the deployment, scaling, and operation of application containers.

Error handling in software development is crucial to identify and manage unexpected issues during program execution. It ensures graceful handling of errors, preventing application crashes and providing a better user experience.

Conflict resolution in Git often involves manually resolving conflicts that arise when merging branches. Developers must review the conflicting changes and decide how to combine them, ensuring the integrity of the codebase. This manual resolution is a crucial step to prevent introducing errors during the merge.

Effective handling of typography in responsive design involves using relative units such as em or rem, setting flexible font sizes with viewport units, and thorough testing across various screen sizes.

Inheritance is a mechanism by which one class inherits the properties and behavior of another class in OOP. It promotes code reuse and establishes a relationship between classes, facilitating the creation of a hierarchy.

One of the primary benefits of CI/CD is a faster feedback loop for developers. With automated testing and continuous integration, developers receive prompt feedback on their code changes, enabling quick identification and resolution of issues.

Apache Cassandra is a highly scalable NoSQL database designed for handling massive write operations with low latency. It is a distributed and decentralized system that excels in write-intensive workloads.
