The Internet is a global network of interconnected computers that allows users to access and share information. It is composed of the World Wide WEB (WWW), which is a system of interlinked hypertext documents, and the underlying infrastructure of the Internet Protocol Suite (TCP/IP). The term 'Internet' is often used interchangeably with 'WEB, ' but it also includes other services such as email, file sharing, and online gaming. The term 'CYBERSPACE' is often used to refer to the virtual world created by the Internet. The term 'ERA' is used to refer to the period of time in which the Internet has been in existence. Finally, the term 'meme' is used to describe an idea, behavior, or style that spreads from person to person within a culture.
