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

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.

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

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.

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.

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

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

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

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

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 describe the typical components of a data center.

The learner will understand the structural organization of the SDS and be able to find pertinent safety information using the SDS.

In this activity, the learner will understand what denormalization is and when it's an appropriate strategy.

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.

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

In this learning activity you'll examine how database normalization eliminates redundancy and helps maintain consistency within a relational database.

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.

Learners examine the benefits of using blogs in a school setting and then test their knowledge in two exercises.

Learners read an explanation of line graphs and demonstrate their knowledge of the parts of a graph in an interactive exercise.
