Binary System by Bray Avila

  1. 1. The Binary Number System Everyone’s favorite topic!!
  2. 2. Why do we learn about the Binary System? <ul><li>Because this is how computers process information. </li></ul><ul><li>Understanding this system will give us a better understanding of how computers work and communicate with other devices. </li></ul>
  3. 3. Brief History of the Binary Code <ul><li>Binary numbers were first described in Chandashutram written by Pingala in 100 BC. </li></ul><ul><li>Binary Code was first introduced by the German mathematician and philosopher Gottfried Wilhelm Leibniz during the 17th century. </li></ul><ul><li>In 1937 Claude Shannon used the Boolean algebra he learned at MIT in his thesis, which became a starting point for the use of the binary code in practical applications such as computers, electric circuits, etc. </li></ul>
  4. 4. Can you tell me one common form of the binary code? <ul><li>Almost everyone has seen or heard of it… </li></ul><ul><li>It’s extremely common in public buildings….. </li></ul><ul><li>Can anyone guess it?? </li></ul><ul><li>It’s BRAILLE!!! </li></ul>
  5. 5. What is the Binary Code? <ul><li>It’s a set of numbers used to transmit data using only 1s and 0s </li></ul><ul><li>They can be broken down into bits and bytes. </li></ul><ul><li>One binary digit is called a bit. </li></ul><ul><li>Eight “bits” = One “byte” </li></ul>
  6. 6. Base 10 v. Base 2 <ul><li>Numbers today are counted in what’s called a base 10 system. </li></ul><ul><li>We use the digits 0-9 to represent all numbers </li></ul><ul><li>Base 2 uses only two digits (1s and 0s) to represent all numbers. </li></ul>
  7. 7. Translating numbers into binary <ul><li>0 </li></ul><ul><li>1 </li></ul><ul><li>2 </li></ul><ul><li>3 </li></ul><ul><li>4 </li></ul><ul><li>5 </li></ul><ul><li>6 </li></ul><ul><li>7 </li></ul><ul><li>8 </li></ul><ul><li>9 </li></ul><ul><li>0 </li></ul><ul><li>1 </li></ul><ul><li>10 </li></ul><ul><li>11 </li></ul><ul><li>100 </li></ul><ul><li>101 </li></ul><ul><li>110 </li></ul><ul><li>111 </li></ul><ul><li>1000 </li></ul><ul><li>1001 </li></ul>

  9. 9. Group Work <ul><li>Now it’s time to practice what we learned </li></ul><ul><li>Each group will get two worksheets that contain numbers, words, and puzzles to translate into or out of binary code. </li></ul><ul><li>Good luck!! </li></ul>
