World Wild Web
Internet is a net with which we are able to communicate with each other without regard to distance. You can use Internet not only to search documents, which are usually written using a code known as Hypertext Markup Language (HTML), but also to use applications like e-mail, internet telephony, file sharing... Every machine in Internet (computer, mobile phone...) has a unique address whose name is IP address. It is a group of 4 numbers separated by dot which identifies and distinguishes the user.
