The internet is a globally connected network system that uses TCP/IP to transmit data via various types of media. The internet is a network of global exchanges – including private, public, business, academic and government networks – connected by guided, wireless and fiber-optic technologies.
The terms internet and World Wide Web are often used interchangeably, but they are not exactly the same thing the internet refers to the global communication system, including hardware and infrastructure, while the web is one of the services communicated over the internet.
The internet is a massive network of networks, a networking infrastructure. It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the internet. Information that travels over the internet does so via a variety of languages known as protocols.
