History Of The Internet

How did the internet originate?
The Internet originated from a defense project called ARPANET. A group of scientists who had access to supercomputers needed to share information across large distances and what they came up with was the Internet.it all began with a satellite.It was 1957 when the then Soviet Union launched Sputnik, the first man-made satellite. Americans were shocked by the news. The Cold War was at its peak, and the United States and the Soviet Union considered each other enemies. If the Soviet Union could launch a satellite into space, it was possible it could launch a missile at North America.President Dwight D. Eisenhower created the Advanced Research Projects Agency (ARPA) in 1958 as a direct response to Sputnik's launch. ARPA's purpose was to give the United States a technological edge over other countries. One important part of ARPA's mission was computer science.In the 1950s, computers were enormous devices that filled entire rooms. They had a fraction of the power and processing ability you can find in a modern PC. Many computers could only read magnetic tape or punch cards, and there was no way to network computers together.ARPA aimed to change that. It enlisted the help of the company Bolt, Beranek and Newman (BBN) to create a computer network. The network had to connect four computers running on four different operating systems. They called the network ARPANET.Without ARPANET, the Internet wouldn't look or behave the way it does today -- it might not even exist. Although other groups were working on ways to network computers, ARPANET established the protocols used on the Internet today. Moreover, without ARPANET, it may have taken many more years before anyone tried to find ways to join regional networks together into a larger system.
Who were the people most responsible for creating it?







Notes From The Videos..
through the US Military. They were worried about attacks taking their computers. They thought it would be a good idea if the computer could talk to each other. Therefore they started a network called "arpa net" which stands for advanced research project agency.2009-50 years 1957, internet started compueteer only worked on one taks at a time. macth processing. They had to be stored in cold rooms.a remote connecteion had to be installed so that the sdelvelopers could work speratly on computers. TIME SHARING where people can work on a main computer all at once.the first un man satillete was sent into orbit. in order to secure americas technonogloy.ARPANET.
military finacnical commercial 4 netwroks arounf the world that shaterd toshare networks. Instead of duplicatly things they could be shared around the world.


TCP transmission control protocol where data is chopped into bpackets and sent off.
for sending packets and assemblying.
communicastions worked trhoguh radio waves
then they used direct waves which didnt have a long range.
Internet the term was bONMR CHECK IT OUT
to keep all the informayion systems functionings that was the need of the internet. they deleveloped prototcols to talk to each other. s agreed way of doing something.
compueter have protocols of commmunicating with other servers.
protocols are very important.TCP/IP is agreed way of sending data
EVERY COMPUTER AHAS  a address called IP address.Its like a packet of information.
It travels around the network from different bits of hardware.TCP/ip is a protocol transmission control protocol.  Is how computer works Internet proptocols
 MAIN FRAME very powerfulmcomputers
