 What is Cash?

A cache is a form of temporary memory that computers access first to retrieve information immediately. The processes and storage of a cache are much better and faster when compared to the functioning of other memories such as RAM (Random Access Memory) in a computer. However, since the storage memory in cache is limited, it’s not preferable to store old data in cache. The new and more essential data is often stored successfully in it. The type of cache found in computers is known as CPU Cache.

A cache is not only found in computers or phones, but is also found in websites, applications, stored files, and much more. The prime function of cache is the storage of memory. It also includes improving the speed of the programming system, saving data, and duplication of files.

While accessing memory or data in the computer, the device first accesses the cache. If the data from the cache is unretrievable, then the device proceeds to collect it from the RAM. A ‘Cache Miss’ happens when the computer cannot access memory from the cache. The cache memory is often expensive to obtain, hence it is used only by multinational companies or conglomerates.
