The internet is a mesh of networks. It is a network infrastructure. The internet is responsible for the interconnection of billions of computer globally. It forms a network in which computers are able to communicate with one another as long as these computers are connected to the internet.
The World Wide Web, on the other hand, is one of the several modes of information dissemination over the internet. It is a model of sharing information, which is built on the internet. The web uses the Hypertext Transfer Protocol [HTTP] to transmit data over the internet. The HTTP protocol allows the communication of applications in order to share information. Web browsers such as internet explorer, Firefox and Google chrome are used to access the documents in the form of web pages, which are linked together by hyperlinks. In conclusion, the web is just one of the channels of disseminating information over the internet. Other uses of the internet include e-mail [which utilizes Simple Mail Transfer Protocol (SMTP)], Instant Messaging and the File Transfer Protocol [FTP]. The internet is therefore bigger than the World Wide Web.

Wi Fi uses unlicensed radio spectrum, which does not need regulatory approval for deployment. Wi Fi eliminates the need to run cables especially in areas where it would be difficult to do so. In addition, there are a variety of products in the market that one can choose from depending on the uses of the Wi Fi network. Wi fi is a structured infrastructure that has a set of global standards, this makes it easy to use by users at different countries around the world at all times.
Much as Wi Fi has become ubiquitous, it also has privacy risks associated with it. Many people who set up private Wi Fi networks do not take any appreciable steps to secure them.
This might be as a result of their lack of knowledge on how to do this. Unsecured networks can be a source of loss of private data including bank details, personal details or even company information. In mitigating this risk, it is important for users to secure their Wi Fi network by setting up a password and even making the network invisible to others so that only authorized individuals can have access to the network. It is also important to edit all default accounts and passwords set up by the manufacturer so that they are not used to have illegal access to one’s Wi Fi network.
