When you access a website, the computer will perform DNS caching, which means that the data in the form of domain name and IP address of the website that you access are locally stored in the computer for a period of time, so when you open a web page that has previously been opened it will feel faster because the computer has remembered the IP address and it does not need to contact the DNS server. However, which often be a problem is that the DNS cache can sometimes be corrupted and it causes problems like some websites that can not be accessed when the internet connection has no problem. At this point the DNS flush is needed.
DNS flush will force the computer to clear the DNS cache or in other words it forces the computer to erase all memory of the domain name and the IP address associated with the domain name. Once the DNS cache is empty, the computer will start asking for new data from the DNS server and it will build DNS cache from the beginning.
Many people find that the fastest DNS Server list on this page is indeed the fastest DNS Server of all DNS servers that have ever been used. However, not everyone feels the same. The speed of a DNS Server is not only determined by how fast the DNS server to resolve domain names into IP addresses but also the distance between the DNS server and your computer. That’s why sometimes a DNS server that is used by someone is not necessarily appropriate when it is used by others in different locations and networks.
Everyone supposes to look for the fastest DNS and the one that is closest to the location because with the combination, the process of domain “resolving” to the ip address would be much faster and it will be more convenient for you to browse the internet since it feels faster and responsive. Actually, most of ISP (Internet Service Provider) has provided DNS servers to be used by the client and maybe this is the fastest DNS as its location clearly closest to your computer. But, is the DNS reliable enough if it is compared to other public DNS servers? We need to benchmark to find out.
Windows 8 as the latest operating system from Microsoft does have nice interface, effectiveness and better security. However, sometimes we still use the old software that is made in the period of Windows XP and that is not updated by the author.
Indeed, there is a feature “Compatibility Mode” in Windows 8, but this feature is not perfect. There are some older programs that really have to be run in Windows XP.
Windows XP in Windows 8
Dual boot? That’s what you definitely think right now. This dual boot system (Windows XP & Windows 8) on your computer will solve this problem. You can run your old programs in Windows XP and when you will just surf or do other works, you can use Windows 8. But of course this will make the time wasted due to the process of switching between Windows 8 and Windows XP and vice versa that requires a fairly long time. There’s another deficiency in dual boot system. You need a license for Windows XP. Isn’t that bothering?
