What is Cache?

Cache on mobile devices is a small-sized type of volatile memory that stores copies of frequently accessed data to speed up applications. Think of it like a fast lane on a highway.

When you use an app, that app sends requests to the device's storage space. However, the data isn't fetched from the main memory every time. Instead, the cache serves it up straight away for commonly used data, reducing wait times and enhancing the responsiveness of the device.

Types of Cache

There are generally two types of cache that are prominently featured in mobile devices:

Application Cache: This cache stores data from specific applications to speed up interactions. For example, web browsers use cache to save images and files for quicker access next time you visit a page.
System Cache: The system cache is managed at the device level and holds files used by the operating system, helping in loading system functions quickly.

How Cache Works in Mobile Devices

When you access an app, your device first looks at the cache. If the required data isn’t in cache, it then seeks it in the main storage. This layered approach minimizes delay and makes operations snappier.

The retrieval process can start to bog down when multiple apps create excessive cache, leading to performance hiccups. Regular maintenance, like clearing cache, can alleviate these slowdowns, ensuring your device retains its speed.

Benefits of Cache
