Did you know that your browser stores temporary files on your computer whenever you visit any webpage? This is done so that the browser can load the page faster when you visit it next time. This is the reason you will notice that pages you visit often load faster than others on your computer. Even though this seems like an advantage in the beginning, the problem begins when your browser stores too many temporary files known as cache in your computer. This can eat up a lot of space in your computer and slow down the performance. In this regard, it becomes essential to get rid of the browser cache from your system.

What is DNS cache?
The Domain Name System of the browser stores all the IP addresses of the websites accessed by the users on the computer. This is done so that the computer can easily access the IP addresses in the future, even if the servers are changed. In some cases, when websites change their servers, users will get a DNS error. This is where your DNS cache will come in handy and help you locate the new IP address easily. However, you may need to delete the DNS cache if you repeatedly get such errors while visiting such sites. Once you clear the DNS cache, your computer will be able to update the latest IP address of web pages and store them in the cache. Let us see how this can be done in an easy way.
