Lastly
Binary Byte Applet
| Binary Byte Simulator |
|---|
Test your understanding of binary numbers (the 8-bit byte sized) and how they represent decimal numbers (signed and unsigned) and ASCII characters.
-
Choose the type of value you want to see generated by clicking the mouse on one of the buttons to the left of the type names.
-
Click on the switches to construct a byte value. Closed switches are ones and open switches are zeros.
-
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.
-
Explore... assuming the switches are ordered left-to-right, zero to seven, which single bit/switch's value differentiates upper and lower case characters?
-
Explore... which switch or switches can you turn on/off to convert between decimal digits and their ASCII representations?
