When browsing the internet you encounter a large number of 404 errors, or web pages fail to load.
This issue maybe related to a problem with your DNS (Domain Name System) and maybe fixed by forcing the computer to clear/reset DNS.
DNS is like a digital Yellow Pages, but rather than matching peoples names, addresses and telephone numbers. DNS is used to convert IP addresses to domain names. These addresses are stored locally on your computer in something called a “Cache“. Clearing DNS will force your computer to re-download the IP addresses and domain names, thus updating the Cache.
