Grade 7 history of internet

1. I. History of the Internet
GRADE 7- ICT

2. History of the Internet
• Before 1957
• Computer works at one task at a time (Batch Processing)
• Ineffective
• Computers became bigger and bigger
• They must be placed in a cool drums
• Computers produce a lot of bugs
• 1957
• Remote connection have been developed
• Time Sharing came up (One Computer-Multiple Users)

3. History of the Internet
• October 4, 1957 (Cold War)
• First Unmanned Satellite “Sputnik I” was launched by the Soviet
Union
• February, 1958
• US founded DARPA (Defense Advanced Research Project Agency)
• To secure USA’s leading technology
• Data was only transferred by people
• DARPA created ARPANET (Advanced Research Project Agency
Network)

4. History of the Internet
•Foundations of Modern Internet
•ARPANET (Advanced Research ProjectAgency Network) - USA
•RAND (ResearchAnd Development) – USA
•NPL (National Physical Laboratory – England
•CYCLADES - France

5. History of the Internet
• ARPANET (Advanced Research Project Agency Network)
• Developed Mainframe connection to IMP (Interface Message Processor)
• Mainframe as servers took control of program initialization and data
storage.
• IMP network was called IMP subnet
• Network Working group developed NCP (Network Control Protocol) that
later became TCP (Transmission Control Protocol)

6. History of the Internet
• NPL (National Physical Laboratory) –England
• Designed for Commercial work
• A lot of data and file transfer are expected
• Developed “Packet Switching”

7. History of the Internet
• RAND (Research and Development) - USA
• USA discovered long range missiles in Cuba which can reach
USA
• USA transformed centralized network into a decentralized
network
• They uses radio waves as a form of communication
• They must use direct waves which however don’t support long
range communication
• RAND developed “Distributed Network”

8. History of the Internet
• CYCLADES
• Developed interconnection of networks
• The term Inter-net was born
• They used computers as transfer node

9. History of the Internet
• Phone companies in USA developed x.25 protocol and allow service
for internet connection in exchange of monthly charge
• ISO (International Organization for Standardization) – developed
OSI (Open System Intercommunication)- standardizes internet
• TCP was changed into TCP-IP (Transmission Control Protocol-
Internet Protocol) – standard that guaranteed compatibility of all
networks around the globe.
• February 28, 1990 – Arpanet hardware was removed, but Internet
lives on.
