Frequent Questions with Technical Answers
The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.
The basic job of DNS is to convert a user-friendly domain name into an IP address that computers use to identify one another. It works like your phone contact list: when tapping the name, the phone actually sets out to call a phone number behind the scene.
Most of the ISPs (Internet Service Providers) from all over the world offer broadband internet subscriptions. Some of them do it through a technology called PPPoE (Point-to-Point Protocol over Ethernet).
Typical use of PPPoE involves leveraging the PPP facilities for authenticating the user with a username and password.
It also offers an ISP an easier way to track exactly how much bandwidth you are using.
Throughput tells you how much data was transferred from a source at any given time.
Bandwidth tells you how much data could theoretically be transferred from a source at any given time.
