The cache is high-speed memory thatuses the processor of a personal computer to store frequently requested information for a certain time. It qualitatively improves performance because it “tells” the processor where to look for the right information and how to get the data in the fastest way.
Кэш-память напрямую влияет на скорость различных operations, since it preserves the necessary data in advance. The principle of its operation can be characterized with a simple example. To optimize their work, any person tries to arrange things on his desktop in a certain logical order. Most likely, there will be pens, a telephone, necessary reference books, current documentation, etc. It is unlikely that every time someone hides the documents he needs under the annual report five years ago, because it takes time and effort. It is on this principle that the cache memory works. What does this mean at the computer level? In fact, a similar process. All information is contained in the PC in a specific hierarchy. If some information is required more often than others, then they are, accordingly, located closer.
The first instance that deals with the deliveryinformation to the processor of a personal computer, memory is running. Nevertheless, although it is several times faster than a disk, it does not always keep up with the specific needs of this chip. That is why the data that is used more often than others, is transferred to the second level of the cache. What it is? In this case, the memory is located on a separate chip with ultra-high speed, which is placed next to the processor, and in new computers it is generally integrated into the chip itself.
Information used most often, for example,the same commands, moved to a special cell of the processor and is a cache memory of the first level. This is the fastest memory in a personal computer.
Как только процессору необходимо выполнить a certain task, it first analyzes its data in the register. If the information is not there, it refers to the cache of the first level, then - to the cache of the second level. If no information is found there either, the processor accesses the RAM. In the final version, if the necessary data was not found anywhere, the chip reads information from the hard disk. Accordingly, the sooner the processor finds the necessary data, the faster it will complete its task.
Caching technology has the following special features:
While the user is on the Internet, the browserloads web pages, various pictures, scripts, sounds, and lots of other information that may come in handy later. This data is known as temporary files, or browser cache files. This is a fairly complex process, which, in addition to the above, includes many other materials:
This whole procedure, on the one hand, is veryuseful because it significantly saves time in the process of downloading certain pages on the world wide web, and also does not require entering a password on frequently visited websites or when entering e-mail.
However, the materials that personal storesA computer using a cache is data that can be made available to third-party users of the Network. This, in turn, makes it possible to track the user's personal information. In addition, various advertising banners, virus-infected scripts, etc., can also be stored in the cache. In this case, you need to clear the cache memory using the browser’s built-in tools.
As mentioned above, cache is extremelyuseful device that allows you to quickly access your favorite sites. However, the materials collected by the browser take up quite a lot of space and over time, especially if a person spends a lot of time on the world wide web, can lead to a decrease in the speed of a personal computer. In addition, in order to receive current information, you will still need to reload the village, so the cache is not so important here.
Individual attention also deserve special attention.user Anyone who has access to the contents of the cache browser can easily see which sites have been visited, as well as learn passwords from mail, online payment systems and much more. You can protect yourself through regular cleaning of temporary Internet files. During the procedure, however, we should not forget that passwords and logins will also be deleted, so you first need to make sure that all of them are saved and recorded.
In order to clear the cache in this browser, you must perform the following steps:
You should also pay attention to the fact that before you install the cache in the browser below 50 MB, you need to think carefully, because many sites after that will not work properly.
To delete temporary files in this browser, you must perform the following steps:
In this browser, the latest version is extremely simple. You only need to select "Menu" - "Settings" - "Delete personal data."
The cache in “Chrome” is also deleted without anyproblems. First you need to go to the settings, which are marked with a wrench icon, then select the "Advanced" tab and click on the "Delete browsing data" button.
In addition, the browser cache can be deleted whenthe help of special programs-cleaners. In addition to temporary Internet files, these programs also clean the registry, which has a positive effect on the operation of the operating system and frees up additional hard disk space.
The cache is high-speed memory, whichallows you to quickly access the processor to the necessary information, thereby qualitatively increasing the performance of the personal computer. The cache is also used by browsers and requires a simple cleaning procedure.
