2. What is cache memory for?
As the name suggests, cache is responsible for storing browsing data and information , whether from websites or applications, on computers, notebooks, tablets and cell phones.

3. In general, how does it work on digital devices?
To understand the action as a whole, let's use a very practical off page seo service and common example... Every time you access a website for the first time, the cache memory saves all the information (text, layout, images, etc.) in codes within your equipment. That's why we also refer to it as a library.

4. But, after all, what is the importance of all this?
What happens is that, if it weren't for the cache — to access any web page or mobile application — the equipment would have to resort to RAM memory, a more complex process that, consequently, takes more time.



So, to simplify and optimize everything, the cache memory takes over the role and displays all the information and data quickly.

What are the types of cache?
Now that you know what cache is, what it is for and how it works, we can talk about the types that exist. Yes, this type of digital library is divided into three levels in relation to RAM memory.

Just look:

L1: the closest;
L2: is “in the middle of the road”;
L3: the furthest.
But what does this mean? The fact is that the closer the cache is to RAM, the faster it is at collecting data and responding to user commands.

5. How to clear cache memory?
When it comes to cache memory, one of the most common questions is exactly this. This is because cleaning it frees up more space and optimizes the performance of devices.

To clean it up, simply access your browser or mobile app settings. But at the same time, it's also important to remember that this makes web browsing and using apps less instantaneous, as we explained earlier.

Furthermore, it is worth noting that there are other ways to save storage space on your devices. One of them is to save photos, videos, documents and more in the cloud or on an external hard drive.
