What is network cache?

O network cache It's like a “quick memory” on your computer or cell phone, which temporarily stores information from websites you visit frequently. When you access a page on the internet, your device saves some information from that website so that it can load it more quickly next time. This is like remembering where you saved your notes so you don't look for them again every time you need them. Network caching helps save time and make internet browsing faster.

There is also the Flush DNS. Sometimes your device may store wrong or outdated information about how to find some websites. Flush DNS clears the old information and makes your device re-search the correct addresses for the websites you visit. It's like making sure your computer is using the right GPS to find the right path on the internet.

Both are related to the way systems store and access information to improve the internet browsing experience. But then, how do they relate? Think of the network cache as a kind of “quick notes” to store important information from the internet. Within this memory, there is a part called DNS cache, which stores addresses of the websites you visit. Flush DNS is like pressing a “clear” button on that part of the memory, helping you solve problems when you can't access some websites.

In short, network caching is a broader concept that includes temporary storage of various types of data to improve overall network performance. Flush DNS is a specific action that can be performed to clear the DNS cache and resolve website access problems. They all work together to optimize internet browsing, providing faster and more efficient access to online resources.

You may have also heard about “data cleaning”, right? Although it seems almost the same thing, especially since it involves cleaning the browsing and internet system, cache and data have different scopes and effects. Know the difference:

  • Clear cache: When you clear the cache of an application on your computer or cell phone, you are removing the files temporarily stored by that application. These files may include data such as images, web pages, and more that are stored to speed up loading and access to resources when you use the application. By clearing the cache, you are essentially removing these temporary files but keeping other app settings and data intact. This may help resolve performance issues or free up storage space, but will not affect your personal data or settings.
  • Clear the data: Clearing an application's data is a more drastic action. When you clear an app's data, you are removing not only cached temporary files, but also all data saved by the app, including custom settings, login, preferences, history, and other data related to app usage. This means it will restart as if it were being used for the first time after installation. Clearing the data is a more extreme measure and is useful when you want to resolve serious problems, such as frequent crashes, or when you want to completely reset its settings.

It is interesting to highlight that when we talk about applications, we are also talking about browsers like Chrome, Firefox, Opera etc. To clean one of them, simply access the Settings the one you use and look for Privacy and Security, before clicking the Clear browsing cache ou Clean navigation data.

Remember that it is important to be careful when clearing data as this may result in the loss of important information or the reset complete application settings.
