The Internet is a global network that connects multiple devices (including computers, mobile phones, game consoles, tablets etc.) and forms a virtual world that allows people to communicate or exchange information with each other. There are different ways for users to communicate over the Internet, including electronic mails (e-mails), Internet telephony, instant messaging, social media, peer-to-peer file transfer or text and video chatting. The most known and widely used application of the internet is the World Wide Web (WWW) that uses the hypertext, which allows the user to access a large number of pages of information. The Internet has reshaped multiple services including telephony, television, newspaper, books publishing, personal interactions, shopping, and finances. However, certain aspects of the Internet can also have negative impacts on people's life.
