The Internet is an international computer network in accordance with certain communication protocols. Internet is a two computers or two or more computer terminals, the results of the client, server linked to each other by means of computer information technology, people with friends thousands of miles away can send each other e-mail, completed a work, common entertainment.

In the 1950s, communication researchers recognize the need to allow for regular communication between different computer users and communication networks. This prompted the study of decentralized networks, queuing theory and packet-switched. U.S. Department of Defense Defense Frontier Research Projects Agency (ARPA) for the Cold War to consider the establishment of the ARPA network in 1960 led to technological progress and make it become the center of the development of the Internet. 1973 ARPA network expanded into the Internet access in the first batch of the United Kingdom and Norway computer.

ARPA in 1974, Bob Kane and Stanford Whedon Zeff TCP / IP protocol defines the method of transmission of packets between computer networks. January 1, 1983, the ARPAnet to the core of the network protocol from NCP to change the TCP / IP protocol.

The bottom of the IP protocol for packet-switched network to a data-oriented protocol, this protocol defines the format of the packets in the Internet transmission. Currently the most used is the IPv4 version, this version is used as defined in 32 IP address, address a total of 4.3 billion, but still can not meet the needs of today's global network of rapid development, so the IPv6 version came into being. IPv6 version, IP address, a total of 128, almost every grain of sand on Earth to assign an IPv6 address. IPv6 and the current popularity of the Internet service provider does not support connection to the IPv6 protocol. However, it is foreseeable, the help of IPv6 in the future, any household appliances are likely connected to the Internet.
