At the present, the internet has turned out to be a significant part of people’s lives.

In other words, this huge and significant software component of the Internet is responsible for distributing data, information and content in the form of HTML pages. In addition, these web pages and information are accessed and viewed by using free software known as web browsers (Gil, 2013).

The DNS and Directories As discussed above, the data and information on the Internet can be accessed through web sites and these web sites use proper names, which are known as domain.

Moreover, these directories allow people to connect to computers by making use of names instead of numbers.

Navigational Tools and Search Engines Basically, the navigational tools are software applications that are used to navigate a web site.
