How does caching improve the performance of RESTful APIs?

Caching in RESTful APIs refers to storing frequently accessed responses so that they can be quickly retrieved without re-executing the entire request. This reduces server load by serving cached responses instead of processing requests repeatedly. It speeds up data retrieval by providing quick access to pre-generated responses, minimizing the time taken to fetch data from databases or external services. Caching also helps minimize network latency as cached responses are served closer to the client, reducing the round-trip time for data transmission. However, caching doesn't directly relate to data encryption; it focuses on improving response time and reducing server overhead.
