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.

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.

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

In this interactive and animated object, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts. A quiz completes the activity.

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

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 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 solve three binary subtraction problems using the 2's complement method.

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

Students use the Base Minus One Complement method to perform binary subtraction. This learning activity has audio content and immediate feedback.

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

Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.

Learners examine a table containing the names of common cations and anions. They then check their knowledge by answering a series of questions.

Learners read how to calculate the MOD number and how it is used.

In this rapid-fire game you'll be challenged to identify various database field types.

You'll be introduced to the basics of quantifying Bits and Bytes.

In this learning activity you'll practice using the 4-input truth table.

In this learning activity you'll explore the operation of frequency division using several different types of counters.

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