  3. 3. Flow Through A Computer <ul><li>Input- when the data starts its journey. </li></ul><ul><li>Memory- when the data is recorded to your computer. </li></ul><ul><li>Processor- when the data is processed to human understanding. </li></ul><ul><li>Output- when the data is translated to the human language, and the product of the process is complete. </li></ul>
  4. 4. Life in Color! <ul><li>The color television came out in color in 1960. This means that the computer may have had color too. </li></ul>
  5. 5. Communication advances: Telstar is launched! <ul><li>the Telstar is a satellite launched for all communication purposes. Telstar 1, launched in 1962, was the first communications satellite capable of both sending and receiving radio, television, and telephone signals. </li></ul>
  6. 6. The ides of the Internet <ul><li>The idea of the Internet was first envisioned by Joseph Carl Robnett Licklider. He e ncouraged research into time-sharing at MIT, SDC, Berkeley, UCLA, etc and distributed enough money to incubate the formation of computer science departments that eventually would be linked up via the ARPNET. </li></ul>
  7. 7. The invention of the Mouse <ul><li>The mouse was first conceived by Doug Engelbart in the early 1960’s, then a scientist at the Stanford Research Institute, in Menlo Park, California. The original mouse had the cord in front, it was a simple mechanical device with two perpendicularly mounted discs on the bottom. You could tilt or rock the mouse to draw perfectly straight horizontal or vertical lines. </li></ul>
  8. 8. Back to The BASICs: the first computer language <ul><li>In 1963-64 Thomas Kurtz and John Kemeny designed and built a time-sharing system, which later became the backbone of the General Electric Time Sharing network. It was a system meant to be easy for ordinary people to use, and one of its ingredients was the new language BASIC. The design goals for BASIC included ease of learning for the beginner or occasional programmer, hardware and operating system independence, the ability to accommodate large programs written by expert users, and sensible error messages in English. </li></ul>
