Bandwidth is a term that describes the amount of data that can be sent and received over a network connection in a given period of time. It must not be confused with the term “Data Transfer”. Bandwidth is measured in bits per second (bps), kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps).

A higher bandwidth results in more data being transmitted in a shorter time frame, allowing for faster communication and data transfer.

Bandwidth depends on the quality of the network connection, the number of users sharing the connection, the type of data being transmitted, and other factors. Bandwidth is often a key factor when organizations choose any web hosting or cloud service provider.

The Domain Name System is an Internet naming system that makes it possible to assign domain names to groups of Internet resources and users, independent of each entity’s physical location. Domain names are easier to remember than IP addresses such as 207.75.188.166 (IPv4) or 2001:db6:1f70::999:de8:7648:6e8 (IPv6). Internet users use domain names to recite meaningful Uniform Resource Locators (URLs) and e-mail addresses.

The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating name servers for each domain. Name servers are responsible for their particular domains. The are DNS distributed and fault tolerant. This makes possible for the WWW to avoid keeping everything in a single central register which has to be continually consulted and updated.

Domain Name System also stores information about the list of mail servers that accept email for web addresses. Domain Name System is a very important component of the Internet as we know it because it provides a distributed keyword-based redirection service.
