A cache memory provides the ability to temporarily store and save data for use at a later time. One often finds usernames, search-engine searches, and websites present in the cache memory.


A cache is practically a reserved storage place that gathers temporary data to help browsers, websites, and applications load quicker. All devices and software have cache - computers, laptops, phones, applications, and web browsers. The cache is responsible for quickly retrieving data, which helps devices function faster. Just like a memory bank, a cache makes it easier to gain access to local data rather than redownloading the data every single time one visits a site or runs an application.
