Week 1 - Introduction to Internet



It is amazing how far the internet has come today, and what impacts it has made. It has definitely shaped many of people's lives and changed many things. Look at the number of users of the internet that has increased drastically over a short amount of time. Hours and hours are spent on the internet, millions are using it.

What exactly does the word 'Internet' mean? It is a collection of computers connected to form a global networked environment. And we use a medium called the Web. Not spider-WEB but just Web, which is a system of interlinked hypertext documents contained on the Internet. Thru this we can see images, text, videos, GIFs, etc... and we navigate through to the next 'page' via hyperlinks.

Which looks like this:




What I learnt most was the evolution of the web from web 1.0 to web 2.0 and currently web 3.0




Web 1.0
It is the “readable” phrase of the World Wide Web with flat data. In Web 1.0, there is only limited interaction between sites and web users. Web 1.0 is simply an information portal where users passively receive information without being given the opportunity to post reviews, comments, and feedback.
Web 2.0
It is the “writable” phrase of the World Wide Web with interactive data. Unlike Web 1.0, Web 2.0 facilitates interaction between web users and sites, so it allows users to interact more freely with each other. Web 2.0 encourages participation, collaboration, and information sharing. Examples of Web 2.0 applications are Youtube, Wiki, Flickr, Facebook, and so on.
Web 3.0
It is the “executable” phrase of Word Wide Web with dynamic applications, interactive services, and “machine-to-machine” interaction. Web 3.0 is a semantic web which refers to the future. In Web 3.0, computers can interpret information like humans and intelligently generate and distribute useful content tailored to the needs of users. One example of Web 3.0 is Tivo, a digital video recorder. Its recording program can search the web and read what it finds to you based on your preferences.
