The term ‘caching’ refers to the process of storing frequently accessed data in a temporary storage area, known as a cache, to speed up data retrieval. When users request data, the system first checks the cache; if the requested information is available, it can be delivered much faster compared to retrieving it from the original source. Caching is commonly used in web applications, databases, and operating systems to enhance performance and reduce latency. Effective caching strategies can significantly improve user experience and resource efficiency by minimizing response times.
