Binary Numbers and Computing

  1. 1. The Keyto Binary Numbers and Computing<br />
  2. 2. First, some key terms:<br />Computer<br />Bits<br />Bytes<br />Binary Counting<br />Decimal<br />
  3. 3. What is a Computer?<br />Simply put,<br />a machine that flips binary digits on and off.<br />
  4. 4. Bits and Bytes<br />A bit is a single binary digit. (This is a useless amount of information)<br />But, when you group them together and have 8 bits, this makes 1 byte. <br />
  5. 5. Bits and Bytes<br />A single byte can have up to 256 different combinations of 1s and 0s. <br />Typically information is broken up into bytes to be stored, calculated, or transmitted. <br />
  6. 6. Binary Counting<br />We count by using the numbers <br />0 through 9. <br />Then when we start all over again, <br />we put a 1 for the first digit and increment the second digit from 0 to 9 again. <br />
  7. 7. Binary Counting<br />The same goes for binary, except that we can only use the numbers 0 through 1. <br />Check out this counting:<br />
  8. 8. Binary Counting<br />Decimal<br />0<br />1<br />2<br />3<br />4<br />5<br />6<br />7<br />8<br />9<br />Binary<br />0<br />1<br />10<br />11<br />100<br />101<br />110<br />111<br />1000<br />1001<br />
  9. 9. If you can count, you can learn the binary system!<br />
  10. 10. First, let’s watch this...<br />http://www.youtube.com/watch?v=b6vHZ95XDwU<br />
  11. 11. Now, let’s do this...<br />http://www.youtube.com/watch?v=Pz7dLWvi2w0<br />(This movie will not be viewed, it will be acted out by the class as it is on the video.)<br />
