Binary Byte Applet

Test your understanding of binary numbers (the 8-bit byte sized) and how they represent decimal numbers (signed and unsigned) and ASCII characters.

  1. Choose the type of value you want to see generated by clicking the mouse on one of the boxes to the left of the type names.

  2. Click on the switches to construct a byte value. Closed switches are ones and open switches are zeros.

  3. After you tell yourself what the value should be, click on the equals sign to get the program to do the conversion and verify your answer.
