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

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.

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

In this interactive object, learners read how to arrange numerical data manually by using ascending or descending order. They also practice arranging the data using a spreadsheet.

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.

Learners examine the elements of a data file memory of an Allen-Bradley SLC-500 programmable controller. A quiz completes the activity.

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

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

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

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

In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.

In this learning activity you'll use the Empirical Rule to calculate the percentages of data between two data points.

In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.

In this learning activity you'll describe the typical components of a data center.

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.

You'll be introduced to the Go-Back-N ARQ, learn what it is, and find out how it's used to keep track of data sent between networked computers.

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 how database normalization eliminates redundancy and helps maintain consistency within a relational database.

In this learning activity you'll examine how routers transfer data between local area networks and the Internet.

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.
