Current and Voltage Parameters of Digital Circuitry (Screencast)
In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.
In this learning activity you'll explore normal distribution and enter values for the mean and the standard deviation of normally distributed data and observe the resulting changes in the shape of the normal curve.
In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.
The Operation of a Multiplexer/Demultiplexer Circuit
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 animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.
In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.
Grouped Numerical Frequency Distributions: An Overview -- First in a Series
In this interactive object, students read about organizing data in a tabular form. A brief quiz completes the activity. This is the first in a series of six learning objects.
In this learning activity you'll explore why the FTP protocol is often used to transfer data across the network and more importantly, why it should not be.
Learners use peripheral vascular assessment data to examine characteristics of these four conditions: peripheral arterial disease, deep vein thrombosis, chronic venous insufficiency, and acute arterial occlusion. A matching exercise completes the learning object.
