Learners are introduced to the binary-coded decimal, a common way of encoding decimal digits in computing and electronic systems. A brief quiz completes the activity.

In this learning activity you'll practice calculating the between the binary number system and the decimal number system.

In this learning activity you'll examine a systematic method for converting a decimal number (base 10) into a binary number (base 2).

In this learning activity you'll examine two methods for converting a binary number to a decimal number.

Students test their skill at converting binary numbers to decimal numbers. Immediate feedback is provided.

Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.

Learners will understand how binary-coded decimal information is decoded and used to drive a seven-segment display.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

In this animated activity, learners examine the construction of a binary counter using a JK flip-flop. The ability of the JK flip-flop to "toggle" Q is also viewed.

Learners examine two methods for converting an octal number to a decimal number. Exercises are provided at the end of the learning object.
