The Internet is a wide area computer network using IP. In other words, the Internet is a global information communication network formed by a communication system with IP addresses assigned to computers as destinations.

From the viewpoint of a computer network, the Internet is a WAN (network of networks) that connects LANs (networks) that can communicate with each other using MAC addresses or the like. As long as communication exchanges between LANs are established, interconnection between networks using IP can be realized, that is, connection to the Internet is possible.

The establishment of the Internet has facilitated communication between computers on a global level. As a result, various applications are developed on the Internet. From early file transfer, e-mail, hypertext documents (Web), and more, to P2P file sharing, voice communication, web applications, and media streaming, the evolution continues.
