What does it mean to clear the cache: why to clear it + 3 ways to clear the computer + clear the cache 4 types of browsers + 2 ways to clear memory on Android + 3 ways to clean iPhone.

Computers, tablets, phones need competent operation and technical support if you want their work to be correct, fast and smooth.

One of the most important manipulations to keep the PC "fit" is the decision to clear the cache.

Let's consider, what does it mean to clear the cache and how to do it on different browsers and operating systems.

What is cache?

Cache Is a cache memory (buffer) for temporary data with a high access speed and limited volume.

It is needed to speed up access to data that is often used. Caching is used by the PC's central processor, hard drives, browsers.

Browser cache- storage of temporary data loaded from network resources. The Internet browser saves temporary documents on the hard drive of the PC.

When pages from the Internet are viewed in the browser, it automatically saves some parts of the page in the computer's memory in order to take data not from the site server, but from the system memory when re-viewing the page, which significantly increases the speed of opening the page.

It is easy to verify that the caching process is working.
Open any site that is new to the browser, then close it.
When you reopen the site, it will load much faster than the first time.

The Internet browser does not cache all files and data. It depends on the settings of each site that the webmaster sets.

What does it mean to clear the cache?

The cleaning process involves the removal of temporary files saved when working with data, sites. What does "clear cache" mean? Erase all graphics and text files.

In the next session of the browser, it will again take information from the site server, and again will save the received data to the system memory.

Why clear the cache?

Since temporary documents are saved on the hard drive of the computer, over time they take up unnecessary space, which affects the speed of the operating system.

This is reflected both in the operation of the computer itself and in the operation of the browser.

If several browsers are used, each of them saves data to the system memory, thus the information is duplicated.
Accordingly, it takes up more space.

There is one more reason why it is necessary to clean up memory: pulling data from hard disk, and not from the server, the Internet browser may not show the updates that have occurred on the site.

How do I clear the cache on my computer?

Cleaning unnecessary computer files cannot be called a simple procedure, in contrast to a similar cleaning of the browser.

But if your PC starts to freeze, you can most likely say that such a cleaning will help restore performance to it.

Let's consider the process of deleting temporary documents for the most popular operating system - Windows.

When cleaning, you can use the built-in tools or special programs. Standard cleaning with Windows tools is considered more effective, but it takes more time and skill.

Standard cleaning windows consists of 3 points:

• clear the cached DNS memory (the system for obtaining information about domains);
• deleting cached files from thumbnails (folder with thumbnails of viewed images);
• clear cache memory.

a) Clear DNS cache

Enter the "ipconfig / flushdns" command into the appeared program without brackets.

As a result, the computer itself cleans DNS from unnecessary data.

b) Clearing the thumbnails of the cache

To launch it, follow this path:

1. Go to the start menu.
2. Find "All Programs" in it.
3. Then " Standard programs».
4. Then "Service".
5. And finally, "Disk Cleanup".

You will see the "Select Disk" window. Choose the hard drive where Windows is located (usually on the C drive).

Your thumbnails cache is now empty.

c) Clear cache

Another way to delete unnecessary temporary documents from your computer

shown in the video:

And do not forget to empty the "Trash", the data in it can also take up a lot of space.

d) Special programs for clearing the cache

To clear unnecessary data in the "RAM" of the computer, it is convenient to use special programs.

There are many such services, but the most popular is Ccleaner.

This program is free. Finding it on the Internet and downloading it to your computer is not difficult.

The official website of the developers, from which you can also download free version programs: http://www.piriform.com/CCLEANER

You can also use the online version without installing on a PC.

To clean your PC with Ccleaner, open the program on the "Cleaning" tab.

On the Windows tab, you can select the data you want to delete. Typically, automatic setup is fairly accurate in identifying such documents.

The program will remove unnecessary files from your computer, including those saved by Internet browsers and other software.

Click on the "Analysis" button and wait for it to finish. Then click "Cleanup".

They also need to dispose of unnecessary documents. And this should be done more often than on a PC, since the amount of "RAM" is less and the system quickly starts to slow down.

1) Clean up memory on Android

V operating system Android has 3 kinds of cached memory:

The essence of the problem

Probably already faced with the fact that when the design or content was changed on the site (information was replaced), then go to the page, and you see the same thing there, no changes, although the programmer reported that the work had been done.

You have already visited this page before, so now you see not the current version of the page, but its cache copy, which is stored in order to more quickly serve it at the user's request.

The problem is solved - by clearing the cache, which allows you to download the page to your computer or smartphone up-to-date, with all the fresh changes.

What is website cache

A site cache is a collection of the most frequently used objects in the process of work: images, html templates, js, css files, as well as the results of queries to the site database.

The process of caching resource objects into the cache is called site caching. The cache has its own storage period, usually no more than a month, after that, a new download of all files from the server occurs.

Caching works to increase the speed of loading pages of the site by users, in situations where typical data can not be loaded from the original source (from hosting), but loaded faster from the saved cache (history). That is, caching allows you not to download the same files several times, which decently speeds up the performance of the site.

What is caching for

The main purpose of the site cache, like any other, is to speed up the work of a web resource, program, service and other products that use it.

The increase in performance is achieved due to the fact that retrieving data from the cache takes much less time than requesting it from direct storage.

In addition, before placing data in the cache, they are often processed, compressed, reduced in size, which further increases the speed of work.

Applications interact with the cache as follows:

1. when the data is requested for the first time, they are entered into the cache;
2. when called again, they are already taken from the cache, and not from the source;

If the cache is empty or the data is considered obsolete, then it is requested along a direct path and this algorithm is repeated.

Site cache retention settings are stored in the configuration files of the web servers and the resource itself.

Types of caching

There are two types of caching, server and client (depending on the hosting capabilities and the site itself), sometimes these two types of caching are used together.

Server site caching

With this type of caching, files are stored on the server (hosting) side. For this, the caching mechanism inherent in the platform of your resource (CMS, framework, etc.) is used.

In this case, as a rule, static html pages and the results of queries in the database are cached. In this case, the cache of sites can be stored both in the form of separate files and placed in the RAM of your remote server.

On some high-load projects, even a separate server is allocated to store the site cache.

Site caching settings in this case are located in the code and special configuration files of your resource.

Client site caching

In this case, the site cache is stored on the client side, i.e. it is your users' web browser cache through which they access the resource (i.e. in the browser).

The browser cache stores only static files (those that do not change during operation) - these are css, js and media files (images, videos, etc.).

But these are not the cache settings on the hosting itself, as you might think at first. That is, the hosting itself does not create a cache of sites on the Internet, but simply tells the clients' web browsers how they need to cache.

Now the most interesting thing is how to reset the cache of the site?

• How to reset the cache to view the changes made on the site - open the site and the desired pages, just press the refresh button in the browser window or press the F5 key on the keyboard.
• If the first option does not help, then there is a universal method: while on the site page (in any browser), press the Ctrl + F5 key combination on the keyboard - this means an absolute reset of the cache and a full download of the site files again. This method is recommended to be advised by your client if they have problems with the project cache. A very simple and effective method, in rare cases, it may not help, and then we use the following options.
• Another cache option occurs when using special plugins and modules for CMS (content management system, engine, for example WordPress, Bitrix, OprnCart, etc.) - usually this cache is reset in the browser when the Ctrl + F5 keys are combined. If, you use such plugins in your site (plugins for each control system are completely different and there are quite a few of them), you need to generally throw off the project cache, then this is done from the site admin panel (for each plugin and engine this is done differently, the developer must explain how to do this in a particular case). It is not difficult, literally in two or three mouse clicks to get to the desired button in the admin panel and press it.
• There are complex caching at the server level, when using it, in rare cases, it may not be enough to use the Ctrl + F5 key combination, completely reset the cache in the browser or in the admin panel of the site, in this case, you need to ask the developer to reset the cache at the server and hosting level ( this happens very rarely).

We will also tell you how to clear the cache in the most popular browsers.

Clearing the cache in the Opera browser

Press the keyboard shortcut: Ctrl + F12. A window will open in which we find a tab with advanced settings, then open the "History" section, select "clear" next to the "cache" item and click "Ok".

Clearing the cache in Google Chrome and other Chromium flavors

Let's use the keyboard shortcut Ctrl + Shift + Delete, which will bring up the history clear window. In it, we need to check the box next to the inscription: "Clear cache" and select the time period for which we will clear the cache. Most often, all-time cleaning is sufficient. Then we confirm the deletion? by clicking the corresponding button - "Delete data"

Clearing the cache in the Mozilla Firefox browser

All actions here are very similar to the previous browser. Again, press the combination Ctrl + Shift + Delete, then in the window that opens, select the "Delete" tab, and then select the "All" item. And finally, you need to put a check mark next to "Cash" and click on the "Clear now" button.

Deleting cache in Yandex browser

A very similar procedure as in the aforementioned Chrome. We need to use the keyboard shortcut Ctrl + Shift + Delete, in the dialog box that has opened, it is necessary to mark the checkbox next to the "Clear cache" item, select how long we want to erase and click "Clear history".

Clearing the cache in Internet Explorer

We find the "Service" tab, in which we select "Internet Options".

We will open a window in which you will find the "General" tab. Find the browsing history in it and click the "Delete" button there.

A new window will open, in it we find the item "Temporary Internet files" and click "Delete files", after which we again confirm the deletion.

Conclusions and generalizations

You can now clear the cache specific page site or the entire browser!

Caching - this is ensuring the speed of the site, speeding up the loading of the site and its pages, it is a very useful and effective tool.

The problems that can be minimal with the cache are the following:

• changes on the site are not displayed;
• the site page and objects on it are not displayed correctly.
• sometimes there may be problems with the site's shopping cart (feedback forms, online calculators), it is impossible to place a new order with a client, send a message to the site administrator, or calculate the order in the calculator.

In conclusion, it is worth noting that on most modern site engines and hosting, the cache is configured and reset very easily, without the use of special knowledge. That is, it is enough to press the key combination Ctrl + F5 on the keyboard, while being on the desired page of the site.

First of all, let's figure out what is browser cache... The web pages that you browse on the Internet are made up of many files:

• CSS styles,
• JavaScript scripts,
• pictures and photos,
• audio and video,
• the web page itself is a text document marked up in a special way, collecting all these files into a common whole.

The first time you visit the site, the browser saves the files that make up the web pages to disk. This special storage on your computer is called browser cache... When you visit the site again, there is no need to re-download all this economy to your computer, since the browser has already saved them in cache... This saves traffic and valuable time.

Over time, however, this repository can grow to monstrous proportions. And even if you no longer visit the pages that own most of the files, they are still stored on your computer. Do you need it?

So if you ask me: "Do I need to clear the browser cache?". I will answer you: "It is necessary!"

Have you encountered any difficulties clearing your browser cache?

I think every PC user has come across such a concept as the browser cache (cache), and also heard about the fact that it needs to be periodically cleaned. But how to clear the browser cache and why do it at all?) We will talk about this in today's article.

In this regard, an unpleasant situation often arises: the page of the site that you recently visited has already changed after your last visit (for example, its design has changed), but you continue to see its old version! Refreshing the page by pressing the F5 key often helps in these cases, but sometimes it does not work. It is very famous for this unpleasant feature of Google Chrome, which is very reluctant to update the cache on its own, without user intervention.

Moreover, if you do not clear your browser cache for a long time, then it will take up a lot of space on your computer's hard drive - up to several gigabytes! In addition, the fragmentation of files on the disk will grow, and, consequently, the speed of the HDD will decrease.

How do I clear my browser cache? This is no big deal! Below you will find a description of the keyboard shortcuts and actions for each type of browser, as they are slightly different.

Ctrl + Shift + Del >> Clear Cache >> Clear History

Ctrl + Shift + Del >> Temporary Internet Files >> Delete

Opera

Ctrl + F12 >> Advanced >> History >> Disk Cache >> Clear

Ctrl + Alt + E >> Clear

Perform the procedure for clearing the browser cache regularly - this will help you avoid many glitches that you periodically encounter. I also recommend that you familiarize yourself with the rest of the list.

P.S. At my last job, cleaning the cache of one of the applications was carried out so regularly and without fail that we have a playful name for this operation "clean the cache"). First of all, if something was buggy, the testers asked: "Did you clean the cache and how long ago?")
