DNS Server: The DNS Server is a Server which is used to find IP addresses of Domain Names. Every computer or Server connected to internet has a unique IP address. We can only communicate or connect with it by knowing its IP address. But as their are too many Websites having different servers so as different IP addresses. It is too hard to remember their IP addresses. To minimize this, we uses DNS server, which converts Website's address like: www.WikiForU.com into its IP address. DNS stands for Domain Name Server.
Database Server: Database Server is a Server which is used to store Data. It gives advanced features for Data storage and data analysis. It is most secure way to save files. Many languages like MySQL are used to communicate with database servers.
Proxy Server: Proxy Server is used to connect to another Server or Host anonymously. It is used to hide identity of your own host or computer. If you are using a proxy server then all your requests goes through the Proxy Server and proxy server is then connected to the other server or client.
Time Server: Time Servers are simply Servers used for providing Standard Time on the internet. These servers are used for synchronization of time and date according to the locations and time zones.
