The learner follows a step-by-step procedure for testing a computer ground circuit.

In this learning activity you'll define what a variable is, how they're used in the C# programming language, and how the computer works with variables under the hood.

In this learning activity you'll review what a variable is, how to use variables in JavaScript, and how the computer works with variables.

Explore Intrusion Detection Systems, what they are, how they're configured, and the types of protection the provide.

In this interactive exercise, learners label the components of a workstation, a Windows desktop, and an application window.

In this learning activity you'll review how a local area network computer uses a subnet mask to determine if its message is intended for a computer on the same network or on a remote network.

In this learning activity you'll examine how a large computer network is configured.

Learners read definitions of terms related to legal, insurance, and advocacy issues regarding the elderly. At the end of the activity, learners test their knowledge in three matching exercises. Some of the programs and groups discussed are Medicare, Medicaid, Social Security, long-term care insurance, OBRA, SSI, and CWAG.

In this learning activity you'll identify Man-in-the-middle attacks and discuss how they affect network security.

This activity is cognitive. Learners will actively listen to a story activated by the computer. Then learners will take a quiz on their comprehension. Lastly, learners will compare their chosen answers against the answer key to determine how well they really did "actively" listen. (Credit given to Tom E. Wirkus, University Of Wisconsin-LaCrosse for this activity.)

In this animated activity, learners listen to instructions for simplifying a complex fraction by finding the least common denominator. This learning object requires a computer that is equipped with speakers.

In this activity we will discover when recursion is the best solution for your computer programming task.

Explore repetition structures, which are commonly referred to as “Looping” statements, are a vital component of programming computer and industrial applications.

Explore repetition structures, which are commonly referred to as “Looping” statements, are a vital component of programming computer and industrial applications.

In this interactive game, learners review emergency medications. For every right answer, the learner earns a square on the tic-tac-toe board while playing against the computer or another contestant.

In this interactive learning object, the student matches the names of software with their definitions and categorizes computer terms according to the appropriate software.

The learner will understand how to set up a Virtual Private Network (VPN) using a home computer network.

Understand the pseudocode structure of variable declarations, a vital component of programming computer and industrial applications.

In this learning activity you'll examine how computers operate in a peer-to-peer network operating system.

In this learning activity you'll explore three common network protocols that computers use to communicate in a network.
