DISK CACHE Meaning and
Definition
-
Disk cache is a hardware or software component in a computer system that works as a temporary storage area for frequently accessed data. It is used to improve the overall performance of the system by reducing the time it takes to retrieve data from the slower main storage devices like hard disk drives (HDDs) or solid-state drives (SSDs).
In terms of hardware, disk cache refers to a designated portion of a computer's memory, specifically the Random Access Memory (RAM) or a separate cache memory chip, that stores data that has been read from the disk. This data is stored in the cache to enable quicker access when needed later, instead of retrieving it directly from the disk. As RAM is significantly faster than disk storage, accessing data from the cache reduces the latency and improves the overall system responsiveness.
Software disk cache, on the other hand, is a technique used by the operating system or applications to keep recently accessed data in the computer's RAM. It works by predicting what data will be needed next and preloading it into the cache, making it readily available for subsequent requests. This caching technique is often used for frequently accessed files, such as operating system files, application libraries, or web browser data, to optimize the system's performance by reducing disk I/O operations.
Overall, disk cache helps to bridge the gap between the slower disk storage and the faster CPU, enabling quicker access and retrieval of data for processing, resulting in improved overall system performance.

Etymology of DISK CACHE
The word "disk cache" comprises two parts: "disk" and "cache".
The word "disk" stems from the Middle English "disk" or "diske", which originated from the Latin "discus", meaning "disk" or "quoit". The Latin term was borrowed from the Greek word "diskos", which referred to a flat round object or a plate.
The word "cache" has its origins in the French noun "cacher", meaning "to hide". It later evolved into the verb "cacher" in English, which means "to store or hide something". The term "cache" is widely used in computer science to refer to a temporary storage space that holds frequently accessed data for faster retrieval.
Therefore, the etymology of "disk cache" combines the concept of a circular storage medium ("disk") and the notion of storing or hiding data ("cache").
