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

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 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 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).

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 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 examine two methods for converting a binary number to a decimal number.

In this screencast, 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.

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.

In this learning activity you'll solve three binary subtraction problems using the 2's complement method.

Learners examine a table containing the names of common cations and anions.

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

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

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

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

Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.

In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.

In this learning activity you'll examine the format of an IP address and interpret the octet by converting between decimal and binary numbers.
