U.S government agencies have realized the importance and potential of internet technology for many years and have been funding research that has made possible a global internet. The ARPA (Advanced Research Projects Agency)
technology included a set of networl standards that specify the details of how computers communicate, as well as a set of conventions for interconnecting networks and routing traffic. Officially named the TCP/IP Internet Protocol Suite and commonly referred to as TCP/IP (after the names of its two main standards), is can be used to communicate across any set of interconnected network. For example, some corporations use TCP/IP to interconnect all network within their corporation, even thogh the corporation has no connection to outside networks. Other groups use TCP/IP for communication among geographically distant sites.
Although the TCP/IP technology is noteworthy bi itself, it is especially interesting because its viability has been demonstrated on a large scale. It forms the base technology for a global internet that connects homes, university campuses and others schools, corporations, and goverment labs in more 61 countreis. In the U.S. The National Science Foundation (NSF), the Department of Energy (DOE), the Health and Human Services Agency (HHS) and the National Aeronatics and Space Administrations (NASA) have all participated in funding the Internet, and use TCP/IP Internet, the global Internet, or just the Internet, the resulting internet allows sesearchers at connected institutions to share information with colleagues around the world as easily as they share it with researchers in the next room. An outstanding success, the Internet demonstrates the viability of the TCP/IP technology and shows how it can accomodate a wide variety of undeliying network technologies.
