Version control is a system that manages changes to a set of files or codebase over time, allowing multiple users to collaborate efficiently. It enables tracking of revisions, facilitates branching and merging, and provides a historical record of changes, which is crucial for debugging and maintaining project integrity.
Time to Live (TTL) is a mechanism that limits the lifespan or duration of data in a computer network or system, ensuring that outdated or stale information is removed. It is commonly used in caching, DNS records, and IP packets to optimize performance and resource usage by preventing unnecessary data retention.
