Description: The ‘App Cache’ is a storage mechanism that allows applications to store data locally for faster access. This temporary storage system is used to enhance application performance by reducing load times and latency in data retrieval. It stores frequently used data, such as images, settings, and query results, allowing the application to access them without constantly making requests to a server or database. Key features of the cache include its ability to store data in fast-access memory, its volatile nature, and its automatic management, which allows applications to decide which data to keep and which to discard. The relevance of the cache lies in its direct impact on user experience; an application that uses an efficient cache can provide faster response times and smoother operation, which is crucial in an environment where users expect instant interactions. Additionally, using a cache can reduce the load on servers, thus optimizing resource use and improving application scalability.
