What does it mean to clear the cache: why to clear it + 3 ways to clean 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 another reason why it is necessary to clean the memory: by pulling data from the hard drive, 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 Windows cleaning 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
DNS cache cleaning is performed using the command line. Go to "Start", select "All Programs", after "Standard", from the drop-down menu open "Command Prompt".
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
Clearing the thumbnails of the cache is done using a standard program.To launch it, follow this path:
- Go to the start menu.
- Find "All Programs" in it.

- 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?

Have you encountered any difficulties clearing your browser cache?
In Moguta.CMS, to speed up the work of the site, some of the content is remembered and in order to see the changes made on the site, you need to reset the engine cache!
If information about a product, category, page or other section has been changed in the admin panel, but the changes have not been applied on the site itself, you need to reset the engine cache.
In Moguta.CMS it is very simple - on the admin panel, in the upper right corner of the page, there is a button "Reset cache".
If you do not manually reset the cache, it will happen automatically after the time specified in the engine settings, by default after 86400 seconds (1 day).
What to do if the changes did not apply anyway
If, after resetting the engine cache, the changes were not applied, then the reason may be in the browser cache.
The browser cache is a place specially allocated in memory where copies of visited pages, pictures and other files necessary for viewing sites are stored.
This procedure is used to decrease traffic and increase page loading speed. In short, when accessing a page, the browser checks for the presence of previously saved copies of the same files in memory, and if there are any, it does not download them from the server again.
So, once visiting any site, its fragments (style files, images, js-scripts) will be stored on your hard disk.
While serving a useful purpose, the cache can play a negative role as well. For example, if you changed the design of the page, but did not see the changes after refreshing it, then most likely the matter is in the cache. Instead of downloading the updated page from the server, the browser simply opens its saved copy.
In this case, you need to reset the browser cache.
In most modern browsers, you need to use the keyboard shortcut to reset the cache ctrl + shift + delete, after clicking, a window will open with the ability to clear the cache.
Google chrome: Keyboard shortcut Ctrl + Shift + Del → Delete the following items: all time → Images and other files saved in the cache → Clear history.
Firefox: Keyboard shortcut Ctrl + Shift + Del → Cache → Clear now.
Internet Explorer: Keyboard shortcut Ctrl + Shift + Del → Temporary Internet Files → Delete.
Safari: Keyboard shortcut ⌘ +, (or ⌘ + b) → Privacy → Delete all website data
Opera 12.16: Keyboard shortcut Ctrl + F12 → Advanced → History → Disk cache → Clear.
Opera 15+: Menu → Other tools → Clear browsing history → Destroy the following items: from the very beginning → Clear cache → Clear browsing history.
Yandex browser: Keyboard shortcut Ctrl + Shift + Del → Delete the following items: all time → check the box: files saved in the cache → Clear history.
When constantly surfing the Internet, the user may notice a number of problems with the web explorer, to fix which you need to know an important thing - how to clear the browser cache. Timely solution of this task allows you to eliminate many problems in the operation of the browser and cleanse the PC of unnecessary "junk". The question is how to do it correctly, because each software has its own interface and features. Below we will consider how to clear the cache memory in the browser, why and when it is necessary to do this work. Knowing these points reduces the likelihood of problems occurring when working with different conductors.
What is cache
To begin with, we note that the word "cache" comes from the English "cache", which in direct translation means "cache". In simple words, these are temporary files with information about visited sites or a copy of web pages. This option is provided to speed up the loading of portals. For example, if the user has previously visited the page, it is not downloaded from the Internet, but pulled from the browser cache. As a result, traffic is saved and download speed is increased.
An equally important question is where the browser cache is stored. In all browsers, the path is identical - C: UsersAdminAppDataLocal. Further "tail" is individual. Let's consider several options for an example:
- Opera - Opera SoftwareOpera StableCache.
- Google Chrome - GoogleChromeUser DataDefaultCache.
- Mozilla Firefox - FirefoxProfileszxcvb5678.defaultcache2entries.
- Yandex.Browser - YandexBrowserUser DataDefaultCache.
- Internet Explorer - MicrosoftWindowsINetCache
In the folders indicated above, you can go to the browser cache and clear it there. So that users do not waste time on searches, the developers of web browsers have provided another way to remove unnecessary "junk" - using the internal capabilities of the software. Alternatively, you can use special software (for example, CCleaner).
How to clear browser cache - all options
Before deleting cookies and clearing your browser cache, you need to understand how your web browser works. Below are the instructions for the most popular browsers.
Yandex browser
The web explorer manufacturer warns that clearing the cache alone is not enough to maintain privacy. A more reliable way is to work in Incognito mode, in which attackers “do not see” the user and cannot identify him. At the same time, you should not ignore cleaning anyway.
The algorithm of actions is as follows:
- click on three horizontal stripes;
- go to the Additional section;
- select Clear history;
- in the Delete entries list, select the time period for which you want to clear the cache;
- activate the option Files saved in the cache;
- turn off all other options (if the task is to clear the browser cache);
- Click on the corresponding clear button.

If you want, you can clear only one of the items (for example, downloaded files, history records, etc.). If you need to clear data from a specific device, turn off synchronization, and then do the cleaning according to the scheme described above.
Mozilla Firefox

Clearing history deletes all files that are retained while browsing the Internet. This category includes not only the cache, but also the list of jumps, page icons, visit history, etc. When deleting, you need to be careful and remove only those data that are no longer useful.
Why clean?
The importance of removing the cache from the browser cannot be overemphasized. These actions are necessary to solve the following tasks:
- Protection of confidential information from outsiders. An attacker will not be able to view the history of visited pages and "extract" classified information.
- Clearing the memory of a PC or laptop from unnecessary files that accumulate over time and slow down (including the browser itself).
- Keeping data up to date. If you don't clean the cache periodically, the web explorer will constantly load old data from different resources. In this case, you might accidentally miss important updates on the portal.
- A guarantee of the correct operation of programs and services. Crashes in the work of various programs or difficulties with loading often occur due to untimely clearing of the cache.
Ignoring the rules discussed above can lead to a number of problems - hacking of software by cybercriminals.
When to clean?
If a person is engaged in website development, clearing the cache is the most mundane and familiar procedure, without which not a single day of work is complete. A common user should have a similar approach. To avoid the accumulation of unnecessary data and reduce the level of security, you need to clear the cache daily. You can use the internal capabilities of your browser to do this work. Alternatively, set automatic cleaning when the program is closed (in some browsers this option is provided). In addition, there are a number of special software with which you can open the browser cache, delete unnecessary information, or quickly remove all unnecessary information with one click of a button.
Have a great day!
