What is tender memory and why is it worth it sometimes?

When you turn on your computer, run a browser or start the game, a data storage system works in the background. This is the cache, also called cache, which acts like a processor assistant, providing him with the information he needed at your fingertips.

How does it work?

The heart of every computer is a processor that constantly processes data. The problem is that the main memory of the computer (RAM) does not keep up with its needs. Therefore, there is a cache between RAM and the processor – A super -fast memory that stores used data most often.

Coverage levels – everyone has their own role

• The processor cache works on three levels. Level one (L1) It is a tiny but instant storage space located directly in the processor. It houses little data, but the processor can use it with virtually no delay.
• Level second (L2) It is bigger, although a bit slower. If the processor does not find the necessary data in L1, he checks here. It is not as close as L1, but still at hand.
• Level three (L3) This is a large magazine. It is the slowest of the three, but still faster than ordinary RAM. In modern multi -core L3 processors, he also plays the role of a coordinator, helping cores to exchange data.

Hand memory in the browser – why is it worth cleaning it sometimes?

The Internet browser intensively uses the cache, saving in it pictures, CSS styles and fragments of websites. Thanks to this, on subsequent visits, the page loads fasterbecause some elements are already saved on the disk and you do not need to be downloaded from the Internet again.

Sometimes, however, cache can cause problems. For example, if the page has been updated and the browser still displays its old version of the cache, this can lead to errors in action or outdated content. In some cases, accumulated data may affect the performance of the browser itselfalthough it usually manages the cache automatically.

In such situations, it is worth cleaning the cache to force the current versions of the pages. This can be easily done in the browser settings, a In case of problems with logging in or personalizing pages, it is also worth deleting cookies.

Not only in computers

Cache technology is developing at its best. Modern smartphones contain advanced Cache systems that make us switch between applications quickly. Even our Smart TV TV uses cache to efficiently buffer stream movies or store data from the application.

An interesting case are hard drives. These inconspicuous devices are equipped with its own Cache system. Thanks to it, large files copy much faster and the operating system starts more efficiently. This is why modern SSDs They are so fast – in addition to great recording technology, they also have efficient cache. Players also give a lot of upside down when it comes to performance. In graphics cards, Cache works at full speed when firing demanding titles.
