Internet protocol suite

Internet protocol suite is the set of communications protocols that implement the protocol stack on which the Internet and most commercial networks run. It has also been referred to as the TCP/IP protocol suite, which is named after two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which were also the first two networking protocols defined. Today’s IP networking represents a synthesis of two developments that began in the 1960s and 1970s, namely LANs (Local Area Networks) and the Internet, both of which have revolutionized computing.

The Internet Protocol suite—like many protocol suites—can be viewed as a set of layers. Each layer solves a set of problems involving the transmission of data, and provides a well-defined service to the upper layer protocols based on using services from some lower layers. Upper layers are logically closer to the user and deal with more abstract data, relying on lower layer protocols to translate data into forms that can eventually be physically transmitted. The TCP/IP reference model consists of four layers [1].

Rudy GiulianiRudy Giuliani makes pitch for personal health insurance and accounts makes pitch for personal health insurance and accounts

Republican Rudy Giuliani is promoting his health care plan in central Iowa.

The presidential candidate spoke today to about 120 people in Fort Dodge. He says his plan would cut by half the nation’s health care costs and let people personalize health insurance policies to meet their needs.

Giuliani says that for his plan to work, he needs more than 60 million Americans to buy their own health insurance and open personal health savings accounts.

Giuliani says he would push for a $15,000 personal income tax exemption to let families buy their own policies. Families could keep whatever amount is left over to open a personal health account.
