Definition of Memory Cache

When in computing we are talking about cache or cache we are talking about that amount of information that remains temporarily in the computer and that helps the acquisition of velocity and efficiency when it is necessary to resort to certain types of data. The name of cache memory comes from French, which means "hidden" or "hidden".

The cache memory system is specially designed to serve the appropriate and organized storage of information on a computer. Its function is basically to keep temporarily and accessible those data that are required to perform certain functions or tasks. Is availability allows each program or file have immediate access to the necessary information and can thus dedicate yourself to raising the level of efficiency of normal functions. Thus, the main memory has a great help that allows you to acquire higher performance speed and better results outside of its limited capacities.

The cache memory is normally structured in small fields where the necessary data is stored (up to one byte of space for each field or

cell). It can take place as an integral part of the main memory as well as it can be located outside it and be activated autonomously. Through the hit rate method or the average number of orders that each data receives, an order of the most important elements is established. required and therefore become more available, eventually erasing those that are no longer available. used.

When one speaks of the disk cache memory, he is referring to a process similar to that of the RAM cache memory that occurs in the same main memory. This procedure is another way to implement the cache memory system avoiding using the slow memory of the HDD but keeping your interior active and providing you with data in a much more direct way.
