What is cache meaning?

Cache refers to a high-speed temporary storage location where frequently accessed data is stored. It is a hardware or software component that stores recently accessed data so that it can be quickly accessed the next time it is required, without having to retrieve the data from the original source. Cache can be found in various computing devices such as CPU chips, hard drives, web browsers, and operating systems. The purpose of cache is to improve the performance of a system by reducing the amount of time it takes to access data. It helps to reduce the latency associated with accessing data from the main memory or storage device, which can be a critical factor in the performance of many computer applications, especially those that require quick response times.
