  2. 2. What is the history of the Internet? • The design of the Internet was done in 1973 and published in 1974. • The Internet is a worldwide network of thousands of computers and computer networks. • The Internet has revolutionized the computer and communications world like nothing before. • The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities. • The Internet got its start in the United States more than 50 years ago as a government weapon in the Cold War. 2 History of the internetory of
  3. 3. Reasons why people use the internet! • 1st Reason. To be a part of society. • 2nd Reason. To get information they need. • 3rd Reason. To communicate with each other. • 4th Reason. To relax and to have fun. • 5th Reason. To watch movies, to read books etc. 3 History of the internet
  4. 4. Who invented the internet? • The initial idea is credited as being Leonard Kleinrock's after he published his first paper entitled "Information Flow in Large Communication Nets" on May 31, 1961. • In 1962, J.C.R. Licklider became the first Director of IPTO and gave his vision of a galactic network. In addition to ideas from Licklider and Kleinrock, Robert Taylor helped create the idea of a network. 4 History of the internet
  5. 5. How was the 1st generation of computers like? • • The 1st generation of computers was from 1940 to 1955. Computers were powered by vacuum tubes and used magnetic drums to store data and memory. • The vacuum tube controlled the electric current through a sealed container. • The magnetic drum is a metal coated cylinder with magnetic iron-oxide material which stored data and programs. • There were many problems with the first generation computers, like many things when they start out. • They were very expensive to make and run, slow and had limited application capabilities. • They also generated a lot of heat and used large amounts of electricity, the ENIAC used 160 kilowatts of electrical power. 5 History of the internet
  6. 6. The 2nd Generation • Then in 1956, the second generation of computers hit. • The vacuum tubes were no longer the best thing for running a computer, the latest component to replace the vacuum tubes is a transistor. • The transistor had a major influence on the development of electronics as it was more reliable than the first generation. • It made the computers smaller, faster, cheaper and more efficient to run. • They were still generating a lot of heat which resulted in the damage of sensitive internal parts of the computer 6 History of the internet
  7. 7. The 3rd Generation • The era of transistors was short lived because in 1964, integrated circuits became the next great thing in developing semiconductor technology. • Computers were made to be more accessible and affordable to a mass audience. • Punched cards and printouts were replaced by keyboards and monitors and the first operating system was created to allow multiple applications to run on one computer. 7 History of the internet
  8. 8. The 4t h 4th Generation • The 4th generation is still the present generation of computers. • When microprocessors where invented in 1971, the era of mass usage of computers began! • The 4th generation was started by the Intel 4004 chip. • Microprocessors have thousands of integrated circuits on one silicon chip. • This chip contained the CPU, memory and input/output controls – a lot more advanced that the last 3 generations. 10 years later, IBM introduced the first computer that was dedicated to the home user 8 History of the internet
  9. 9. How do computers look like today? • Now computers are very thin and weight nothing for example some two or three pounds. Some of the newest computers are: • Samsung - Series 5 Ultrabook 13.3" Touch-Screen Laptop - 4GB Memory - 500GB Hard Drive • Apple 27" iMac Desktop Computer • My favorite is the Microsoft RT Surface 9 History of the internet
  10. 10. Where is the internet used in daily lives of people? • In different places such as schools, hospitals, offices, homes, etc… • In a smart phone internet is the main point, because if it doesn’t have internet then there isn’t that much you can do • I pads, tablets, etc… • Stores to keep things running • Something I found awesome is that now you can even order your subway sandwiches online with the free subway app. 10 History of the internet
