What is cache?

Cache is a storage area dedicated to temporarily storing data that helps websites, browsers, or applications load faster. Cache helps to retrieve data quickly by storing frequently used data, and it won’t take time for a website or application to reload that data.

Where is cache used?

Cache, also known as cache memory, is an indispensable component in modern devices, computer software or phone applications.

Cache used in hardware devices

Cache memory is used in both software and hardware. CPU (Central Processing Unit) is the core component responsible for processing information from software in computers or mobile devices.

CPU Cache is a small block of memory designed to make it easy for the CPU to access frequently used information at a very fast rate to keep up with the CPU’s processing speed. It stores data from frequently used main memory to execute instructions much faster than main memory access speed.

Cache used in software and applications

Apps on your phone or software on your computer also regularly maintain their own cache. Like the CPU’s Cache, applications or software save files or data that they consider most important or frequently used so that when the CPU needs them, they will be available to access and process.

However, applications or software are different and therefore the type of data they store in the Cache also differs. Be it files, thumbnails, search history or other user preferences…

Cache used in web browser

Every web browser maintains their own Cache. It stores the files your browser needs to display the website you visit. It can include an HTML file, a cookie, or an image.

For example, if you go to a Tiki shopping site, it will download everything the Tiki website has to offer such as images, HTML files to display the page layout, elements for presentation and interaction. page and even search history on the Tiki site. That’s why if you clear your browser’s cache, your search history will disappear and you’ll have to wait longer for the web page to reload and show up in the browser.

Benefits of Cache

There are 2 main benefits of using Cache.

Cache makes everything run faster

Cache improves the performance of the entire system. For example, by storing the necessary data of the web page on your computer that the browser has loaded on the first visit and it can be used immediately for the next visit and only downloads new data. or change from the internet to help the page load speed faster.

Cache saves data

Since Cache stores data for later use, it reduces the amount of data that needs to be reloaded like the example given above. The most common is the Facebook application when there is no network, it can still watch some new videos or posts when there is no internet connection. That’s because it has preloaded data in the past and cached it for use.

Disadvantages of Cache

Although devices and software today rely heavily on the use of Cache, they also have some disadvantages.

Cache can take up a lot of storage space

Not to mention the Cache of hardware devices such as CPUs that do not need much capacity, just need extremely fast access speed to keep up with the CPU’s processing speed, the Cache memory for software or applications is The data is stored locally on main memory. This data often includes both new and old data that is no longer in use, grows larger and takes up a large amount of memory space on the device.

Corrupt Cache can cause the application to work unstable

Since the application or software will usually use the downloaded data in the cache first, a problem with the data in the cache will cause the application or software to often behave unstable or not start. get that application.

Does clearing the Cache have any effect?

With the disadvantages mentioned above, clearing the Cache regularly is considered a very effective device maintenance. In addition to deleting corrupted cached files in the Cache, making the application unstable, the Cache memory is too large or the device does not have too much storage space, which will affect the performance of the device. Friend.

Unfortunately, clearing the Cache will also delete files designed to make your device faster and more efficient. For example, clearing your browser’s cache will make it take longer to visit your web pages again, as well as re-login to your account or settings on that site.

Software and applications each have a different way of clearing the Cache, usually it will be easy to find in the settings of that program. Readers can refer to some articles on how to clear the cache memory that GhienCongList has introduced below.
