Study Notes
-
In the early 1960s, the U.S. government was worried that the Soviet Union might attack U.S. military bases, so they developed a system to share information between different parts of the government.
-
This system became known as the ARPANET, and it started operating in 1969.
-
The ARPANET was divided into two networks: the MILNET network was for military sites, and the new ARPANET network was for non-military sites.
-
The development of the ARPANET allowed researchers to work on defense projects without having to worry about the security of their data.
-
The ARPANET was eventually divided into two networks: the MILNET network was for military sites, and the new ARPANET network was for non-military sites.
-
The development of the ARPANET allowed researchers to work on defense projects without having to worry about the security of their data.
-
In the 1990s, the internet began to spread beyond just defense research.
-
The Internet is a system of interconnected networks that allows for the sharing of information between different parts of the world.
-
The development of the Internet was spurred by the need for a system that could handle the large amounts of data that were being shared between different parts of the world.
-
The first network to be developed was the ARPANET, which was created in 1969.
-
The ARPANET was later replaced by the Internet, which is a system of interconnected networks that allows for the sharing of information between different parts of the world.
-
The main purpose of the Internet is to allow for the sharing of information between different parts of the world.
-
The main network that the Internet is based on is the TCP/IP protocol.
-
The TCP/IP protocol is used to allow for the communication of data between different parts of the world.
-
The development of the TCP/IP protocol was spurred by the need for a system that could handle the large amounts of data that were being shared between different parts of the world.
-
In 1966, the Michigan Educational Research Information Triad was formed by the universities Michigan State University, the University of Michigan, and Wayne State University.
-
In 1973, the network was redesigned to hide the network's differences and the responsibility for its reliability was placed on the hosts.
-
In 1978, TCP/IP was finalized and adopted as the networking protocol for the ARPANET.
-
The first UUCP network was built at the University of North Carolina at Chapel Hill in 1979.
-
The UUCPnet was later renamed the Usenet network.
-
In 1981, the UUCP network had grown to 550 hosts.
-
In 1984, UUCP networks had grown to 940 hosts.
-
In 1987, the Rede Sublink network was founded, using UUCP to connect bulletin board systems (BBSs) in Italy.
-
In 1989, the PUUG started selling UUCP connections to the Internet in Portugal.
-
In 1992, the FCCN started registering domain names in .pt.
-
In 1993, the University of Minho opened access to the Internet to its students.
-
In 1996, there were 10 telecommunications companies with license to provide complementary fixed-line telecommunications services.
-
In 1997, the increase in Internet access and the need for a more robust and fast infrastructure led to investments in new technologies.
-
However, due to the lack of an infrastructure for fiber optic cables that covered the entire national territory, initially, networks were set up locally using high-speed local networks.
-
As part of these investments, the backbone was opened to the public in 1995, and has been providing connectivity to commercial providers ever since.
-
Since 1997, there has been a new phase in the development of the Brazilian Internet, with an increase in access to the network and the need for a more robust and fast infrastructure. However, due to the lack of a fiber optic cable infrastructure that covers the entire national territory, initially, networks were set up locally using high-speed local networks.
