DNS Domain Name System
The DNS translates memorable Domain Names/Hostnames into corresponding IP Addresses. Routers across a network route traffic utilising IP Addresses which are unsuitable for use by humans as a means to access websites, email addresses, etc. Instead more suitable representations in the form of HTTP URL (Uniform Resource Locator) or SMTP email addresses are used. This function is carried out utilising DNS Servers operating in a hierarchical architecture.
