Data Representation

Logo for Data Representation
The Data Representation Applet shows six different interpretations for the same string of thirty-two bits. The six interpretations are: a binary number, an integer, a hexadecimal number, a real number, a string of four characters and an eight-by-four grid of pixels. Here is a short explanation of each of the six data displays.

I like the program. It allows students to see information in all the different
representations that we are now learning.

This tool is extremely simple to use. It can be used to help a student learn
conversions from one base to another.

Technical Remarks:

The only thing that I may have taken into consideration that is not currently
included would be conversions on the right side of the decimal point.

This is a good way to practice numeric conversions. Once the user has spent
just a couple of minutes using this applet they will feel more confident
converting from hex-to-binary, etc... This applet will have most impact on the
unsure students that are just learning about data representation. Since the
applet strictly limits the length of data being entered, it's use as a data
"calculator" by the more experience students will also hampered.
