In this learning activity you'll examine how a data file is broken into packets and transmitted over the Internet.

In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.

Explore what DML is including its main commands INSERT, UPDATE, DELETE, and SELECT.

Learners observe animations showing how data is converted between serial and parallel flow.

In this activity, you'll learn about the different data types associated with databases.

In this learning activity, you'll discover and then follow established rules when naming database objects.

Datum precedence is a fundamental principle in the design and manufacture of mechanical parts and assemblies.

It refers to the order of importance assigned to different datums, which are specific points, lines, or planes on a part, which are used as references for measurement and geometric tolerances.

Learners follow the route of the Danube River as it flows through Europe. A map exercise completes this activity.

Learners view step-by-step instructions for how to set up and sharpen a drill bit in the Darex drill grinder, model SP2000.

In this document you'll review the Darex Drill Grinder.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.

Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.

In this animated learning object, students examine the addresses of PLC elements and how they pertain to I/O connections and internal memory files.

The learner listens to and sees Chinese vocabulary words used to describe hobbies, sports, and other pastimes.

Students read about the characteristics of the ideal operational amplifier and compare them with the industry standard LM741C.

Students read an explanation of the summing amplifier and the formulas for closed-loop gain. An example is given.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

In this screencast, learners read how microbes in such items as yogurt, bread, insulin, and insect sprays improve our lives.

Students view a dc analysis of a base-biased NPN transistor.

Learners read about the different uses of the word "data." They will test themselves on examples of data that is singular, plural, qualitative, quantitative, nominal, ordinal, interval, rational, discrete, or continuous.
