What is cache?
Let us take up an example to understand caching better. Whenever you visit a place for the very first time, your brain stores some information about the routes you followed as well as some rough pictures in the mind of the visited place so when you visit the same place again, it is simpler to recall the place. The same way your cached data behaves. Whenever a device visits a website, some data regarding the website is stored in the device and next time when you access the website it is easier and faster for the website to load as the website data is already stored in your device.
You might be wondering if you can access the site with your browser and internet connection again, why there is a need to having cached data?
Why cached data exist?
The vital reason that cache data exist is to improve your load speed of pages and website. If a device already has your layout of the website saved in their device in the form of cached data, it becomes easier to load the data again. This helps in the quick processing and loading of the website.
Cached data can be useful for your devices such as mobile phones, laptops, tablets, etc but it may take up space over the device for storage and over a while, cached data can be corrupted over your device. Though cached data is helpful for the websites that you visit regularly, it is a waste of storage for the websites you visit only a few times.
Android devices can manage data efficiently, but for most of the users that don’t manage their data manually can be a problem. Their device may be facing some issues while you are trying to fix the problems, and you may come across steps that may ask you to clear the cache.
Cache data still exists on your device even if you are not visiting the sites. All websites and applications have cached data for faster load time for users. Since cached data is automatically created and does not include any confidential or important data it is harmless at some point.
Whenever you delete previous data from your website, you will notice some slight changes while you access the website and have an experience that you are using the website for the first time. But the cached data will be created again on your device as soon as you visit the site again. Hence, again when you visit your website again you will notice that your website is faster and smoother again.
How should we clear the system cache?
System cache all the data of the websites you may have even visited once. There can be a possibility that you may have stopped visiting that page or website but the data still exist in your system. It is good to clear the system cache every time so you can free up space on your device.
The website may have saved lots of information on your devices that eventually need more space over your device and cause problems such as being corrupted. Therefore, even it can make your website load time faster it can cause these issues that arise a need to delete the system cache.
How does CMS use caching?
CMS (Content Management System) uses website caching at certain levels. It may cache some individual contents or elements of an entire page that display. It caches files such as images or URLs and is used to optimize their speed. It caches configurations that are used in the backend of the page template for better load speed of your website.
Caching reduces the time taken to display any page in your Web Browser. To display a page for the first time, CMS requires,
- For retrieval of page template from the database
- Easy to assemble auto-generated navigation by skipping hidden menu pages
- Retrieve reusable content easily and faster
- Fast retrieval of visible content such as images or handlers
- Resizing of necessary elements
- Assembling content from plugins
Retrieving and processing data faster to your site is the main reason CMS uses caching that would lower the load over the browser and doesn’t delay viewing pages. Saving the page that will be generated later can be retrieved quickly.
The expenses of using this occasionally clearing cache from your device and forcing CMS to rebuild the pages for displaying the visitors. CMS usually clears the internal caches at midnight daily and be visible back with new pages on your site.
With the only drawback of corrupted memory that can be avoided by manually clearing the cache let us discuss the benefit of caching,
What are some benefits of cache clearing?
As you know, visiting a browser website for the first time on Internet, stores information from the site as temporary files. All web browsers consist of this standard feature, so next time you visit the website the cache copy is loaded from the DNS server over the internet.
The benefits of caching are,
- Enhance System and Application Performance
The cache slows down your system and applications, as it acquires memory on your device. Many times, it is filled with information that is irrelevant and not usable by the user in the future.
The main purpose is to improve the site performance by reducing the data while fetching the website. With a proper amount of cache stored, the speed and optimization are hampered. Your system and website have the benefit of clearing cache.
- New Updated Version of Page is Fetched
As we discussed earlier, the stored data of the webpage is loaded while you search the site. Any changes that are done to the site are neglected due to cache memory and the same old site stored on the cache memory is loaded. This is the reason developers usually insist on cleaning the cache for accessing the newly updated website where changes have been implemented.
Cache clearing will make your browser fetch the latest version of the site.
- Privacy Threat Mitigated
The cache memory also contains private data that is sensitive, such as, login credentials, mobile number, etc. In the case of a public device, the next user after you may get access ver the confidential information that you want to keep private.
If you are worried about your privacy, deleting cache is a great option and it reduces the privacy threat for you.
