Cache
Temporary storage of data or information that can be quickly accessed for later use. Caching is used to improve system performance by reducing data access time. This is achieved by preloading the most frequently used or likely data into the cache. When the system needs to access data, it first checks whether the data is in the cache, which can significantly reduce latency. Caching is widely used in various areas, including web servers, databases, applications and other systems where fast access to data is important.
