"The forerunner of today's Internet network ARPANET. Agency project management research and development under the Department of Defense ARPA link 4 first place in July 1969 include: Stanford Research Institute, University of California, Los Angeles, University of Utah and the University of California , Santa Barbara. It is the inter-regional network (Wide Area Network - WAN) first built.
The term "Internet" first appeared around 1974. At that time still called ARPANET network. In 1983, TCP / IP is officially regarded as a benchmark for the US military and all the computers connected to ARPANET had to use this new standard. In 1984, the ARPANET was split into two parts: the first part was called ARPANET, devoted to research and development; the second part is called MILNET, the network used for military purposes.
TCP / IP is increasingly demonstrated its strengths, the most important is the ability to link to other networks together simple bitter. This, together with the open-door policy has allowed the network for research and commercial connected to ARPANET, promote the creation of a superlattice (SuperNetwork). In 1980, the ARPANET network is considered the backbone of the Internet.
Milestones importance of the Internet is established in the mid 1980s when the national scientific organizations USA NSF established affiliate network centers with mainframes several called NSFNET. Many businesses have moved from ARPANET to NSFNET and so after almost 20 years, is no longer effective ARPANET was decommissioned in about 1990.
The formation of the NSFNET backbone network and other regional networks have created a favorable environment for the development of the Internet. By the year 1995, the NSFNET collected into a research network, the Internet also continues to grow.
With the ability to connect to open such, the Internet has become one of the largest networks in the world, the network of networks, appear in all areas of commerce, politics, military, research, educational, cultural, social ... And since then, the service on the Internet is constantly evolving to create for mankind a new era: the era of trade e-commerce on the Internet.
