Cache

Pay

The money that artists, TV presenters and other professionals charge for their work is called cache.

The concept of cache , which comes from the French word cachet , can be used in different ways. The first meaning mentioned in the dictionary of the Royal Spanish Academy ( RAE ) refers to the money that is paid to an artist or certain professionals for carrying out a presentation or work.

For example: “We were thinking of hiring an American band for the closing of the festival, but the cachet was very high” , “We have not yet agreed on the singer's cachet” , “The coach would agree to lower his cachet to continue in the club” .

A rock group, to cite one case, charges a fee to perform live. Television presenters and football technical directors, among many other workers, also perceive a cachet.

Cache as refinement

Caché, on the other hand, can be used as a synonym for elegance or refinement .

“It will be a party with a lot of cachet” y “The living room still retains its cachet” son expresiones que muestran este uso del término.

Meal

Caché is a conjugation of the verb cachar: "I caught you taking cookies from the fountain when I had asked you not to."

A conjugation of cachar

Caché can also be a conjugation of cachar : a verb that refers to catching, grabbing or getting something .

In phrases like “I caught you! “I saw how you took the cookies from the jar!” , “I caught Nina kissing with Pablo” and “I haven't caught it yet, but I'm going to forget about it…” this use can be seen.

Cache in computing

In the field of computing , finally, a cache is called a quickly accessible temporary memory that stores data that was recently processed.

Although the dictionary of the Royal Spanish Academy indicates that the term cache should be written with an accent , because it is an acute word ending in a vowel, it is common to find it without an accent in computer books, since they use it as an Anglicism; In these cases, it must be written in italics ( cache ) like any other term of foreign origin.

This cache works as a buffer . When accessing data for the first time, the system makes a copy in the cache. In this way, subsequent accesses are made to that copy to save time.

Differences with RAM

Although in terms of technology there is not much difference between the cache memory and the main system memory (that is, RAM), the former has much less capacity and allows considerably faster access. Precisely because of this last aspect, its price is very high, and that is why it is not used in large quantities; To speak in more specific terms, while current computers usually have a minimum of 16 GB of RAM, their processors do not reach 30 MB of cache memory (note that 1 GB is 1024 MB, so the difference is abysmal ).

Since the cache memory is so much smaller than the main one, it goes without saying that it is not possible to store all the data of a current program in it (let's not forget that some usually require several hundred megabytes to execute, an amount that exceeds the capacity of the cache dozens of times). For this reason, the microprocessor stores only the data that it will need to use most frequently, leaving RAM for the rest.

One of the secrets of the access speed that the cache memory can boast over the main one is its location: processor manufacturers place it next to them, while the RAM memory must be installed manually on the motherboard, several centimeters away. of the processor and its performance depends in part on the speed of the components that connect it to it.

Since the microprocessor makes a copy of certain data in the cache memory the first time it accesses it, when it needs to read it again it looks for it there before in RAM; If you find them, then you can work much more efficiently.
