 does not regulate the Internet Because of the simplicity of its protocols, IP, TCP, and HTML markup language, the entire world can communicate over the Internet Voice, video, and data are transmitted on the Internet Carriers exchange traffic at peering points Protocols Used on the Internet The single most important factor in the worldwide spread of the Internet is the standard, easily implemented protocols used on the Internet. Worldwide, all countries use the same IP protocols to transmit data across their sections of the Internet. This means that people access broadband in a uniform way regardless of their location. When the Internet was designed, simplicity was purposely kept in mind SO that the networks could be uniformly and easily duplicated. The www.TechnicalPDF.com fact that these designs are accepted worldwide has been a critical factor in adoption. The following are examples of the Internet protocols: Internet Protocol: IP is a "best effort" protocol. When a message is sent over the Internet, it is broken up into packets. Each packet is sent on a different route and reassembled at the receiving end in the correct order. If there is congestion the router drops packets. The dropped packets are not resent. This is why IP is known as a best effort transmission protocol. HTTP: HyperText Transport Protocol links are the standard way documents are moved around the Internet. HTML: HyperText Markup Language is used to compose web pages. It is not, strictly speaking, a protocol. TCP: Transmission Control Protocol provides error checking on messages sent over the Internet. It is a connection-oriented protocol. Messages are sent between sending and receiving computers on the Internet that communicate whether the message was received or whether errors occurred. If there are errors, bits are retransmitted. IPv4 and IPv6: Internet Protocol V4 and v6 define the numeric structure of Internet addresses. The newer IPv6 was launched in 2012. It specifies longer addresses and is being implemented by Internet providers and
