caching

Caching is a technique used to store copies of frequently accessed data in a location that's quicker to reach than the original source. Imagine a library where some popular books are kept at the front desk for easy access instead of searching the shelves each time. This way, when you need a book often, you can get it faster. Similarly, in computers, caching helps speed up processes by temporarily storing data so programs can retrieve it more efficiently, reducing wait times and improving overall performance.
