In the mid 1980s,another federal agency,the National Science Foundation joined the ARPANET after the department of defense dropped its findings.ARPANET and NSF linked five regional areas with super computers NSF net.The NSF net allowed universities and research agencies to link up with its super computers.Using modern technology, it permitted any computer in the system to link up with any computer connected to the system.The link between ARPANET, NSF and other networks was called the internet.The original ARPANET was shut down in 1990,and government funding for NSF net was discontinued in1995.
