You may have cleaned up your browsing data on your computer, mobile phone, or any other device, or you might have come across an option prompting you to clear cache, and you probably did several times over.

You have come to think of it. What exactly is cache? We have packed together everything you need to know about caches and how they are important to modern-day technology.

What is Cache?

What is Cache?

Cache, pronounced as “cash,” is like a bank that provides temporary storage for data to aid a faster loading rate of websites, browsers, and apps. It makes it very easy for you to access data and retrieve data from your computer, mobile device, apps, or visit a website. This is managed by the operating system, which keeps a page cache in unused memory space (RAM), which aids faster access to the contents of the already cached page.


Cache stores information, unlike content delivery networks which are geographically distributed networks of proxy servers to bring contents to users quickly.

A CPU cache is a small block of memory designed to store temporary files and assist the CPU in retrieving data. A cache is stored in hardware and software. It stores data that your device’s main memory can execute instructions. Software cache is stored in the CPU.

Is It Safe To Clear Browser History?

Is It Safe To Clear Browser History?

Given the drawbacks of cache, it makes a lot of sense for you to clear your cache as routine checkups on your device. The solution is to routinely clear your cache, which deletes the files stored previously in the cache.

In theory, a cache is a small repository of files of use by an app. Caches take up a lot of storage space. Some caches can grow extremely large, limiting your device’s amount of free space. Clearing the cache can erase files and recover memory.

A corrupted cache can cause the app to behave poorly. The app may display data incorrectly, glitch, or even crash. As a result, clearing the cache is a common solution for browser problems.

Caches can prevent apps from loading the most recent web page or other data only if you prefer an older version.

How Can I Cache A Website?

Keep in mind that you would not navigate other sites while doing this. If you wish to view other sites, it automatically becomes a live version. With that in mind, let’s proceed.

  1. On your device, perform a Google search for the page you want to find.
  2. When the search results page loads, click the down arrow next to the site’s URL and choose “Cached.”
  3. The page’s cached version will be loaded. You have the option of viewing the “Full Version,” the “Text-Only Version,” or the “View Source.”


If you begin to notice that your application performance on your pc, tablet, Mac, or Android is below par, it is ideal that you clear cache, although this may probably mean that your stored files, saved passwords of some sites, and some more have to go.
