A repository is a centralized location where data, files, or resources are stored and managed. It can be physical, like a filing cabinet, or digital, such as a cloud storage service. Repositories are commonly used in software development to store code, documentation, and other project-related materials, making it easier for teams to collaborate and track changes. In the context of software development, a popular type of repository is a Git repository. This allows developers to manage versions of their code, enabling them to revert to previous states or collaborate with others efficiently. Repositories can also include metadata, which provides additional context about the stored items.
