User: Camacho epis INTERNET AND THE SITUATION IN PERU In the Internet, specific communications are established between two points: one is the personal computer from which you access and the other is any of the servers in the network that will facilitate information and services such as email, access to the huge existing database cyberspace. One of the important features of the Internet is that it is an interactive communication medium. The core of the Internet is TCP / IP, a transmission protocol that assigns to each machine that connects a specific number that uniquely identifies each computer on the internet. The Internet address is 4 numbers separated by periods in which each number can range between 0 and 255, called “IP number” (which acts as a “single phone number”) such as 161.132.70.7, (Municipality of Miraflores – Lima) would become your email address assigned by your service provider.Another example would be 200.48.26.79 / corresponding to the Virtual Health Library of the University of San Marcos (http://200.48.26.79/BVRevistas/Revista.htm) Region or Country Company Provider of User Company No. Machines in Emp .

When necessary, an automated service called DNS automatically converts these cryptic IP numbers more intelligible words (like www.universidad.edu) to be memorable. INTERNET HISTORY a) General Background 1960, emerges as Draft U.S. Defense DARPA (Defense Advanced Research Projects Agency). ARPA (Research Projects Agency Advanced) Defense Department created a small network that allowed computers to transfer secret information.He defined the TCP / IP with the idea of using this system to ensure communication between remote locations in case of nuclear attack by former Soviet Union. In late 1969 four hosts were connected to this initial network, which grew rapidly during the following years. “There is no doubt that the Internet has grown enormously since the day he was born, as claimed Kleinrock. Until the beginning of the 70s did not begin to create the first applications. Technological progress has continued to grow, one hand the ability of computers to store data and the emergence of optical fiber opening the world of telecommunications: the same support that could carry digital information, images, sounds and texts. Since 1972 when it began investigate how that information packets can move through several different networks and not necessarily compatible. In 1975, ARPAnet began operating as a network, serving as a basis for joining military research centers and universities, and worked on developing more advanced protocols for different types of computers and specific issues. The 80’s spread internationally. Connecting universities and research and education institutions, governmental or nongovernmental, and private and commercial networks In 1983 he adopted the TCP / IP as the primary standard for all communications In fact responsible for the recent explosive popularity of the Internet is with the advent of World Wide Web WWW (website) and hypertext conceived by Tim Berners-Lee with the need to disseminate advances in CERN to the global scientific community. 1990 ARPAnet disappeared to make way with other TCP / IP Internet. Private organizations have begun operating on the Web From this date when the Internet has become a revolutionary new means of communication worldwide.New media developed to make Internet access much easier and enjoyable for anyone have influenced this expansion, turning to the Internet at large global network. From 90, World Wide Web, making the connotation revolutionary paradigm of universal information source. It is estimated that there are thousands of networks of all sizes connected to the Internet, over six million servers and 50 to 60 million people who access their contents 1995, was held in Geneva a conference on “The Use Internet and World Wide Web in telematics and healthcare. Among the decisions taken was to create a foundation. From it emerges Health on the Net Foundation was created to advance the application of new information technologies in the fields of health and medicine. 1996 (May) we made a demonstration of telemedicine via satellite at the Regional Conference on Telecommunications in Africa (Abidjan, Ivory Coast).
