In this learning activity you'll explore how port scanning is commonly used by hackers to infiltrate a network and how IT security professionals can detect it.

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

In this learning activity you'll identify TCP and UDP port states and how they behave during interaction.

In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.

Learners examine how metal detectors function. This object includes animation and sound.

Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.

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 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 examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using if-then-else, calls, unconditional jumps, and counters in this learning activity.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

In this module, we'll be introducing you to SIPOC, a powerful tool that can help you improve your business processes. It's a high-level process mapping tool that helps you identify the key components of a process and how they relate to each other. SIPOC diagrams are often used in Six Sigma and Lean methodologies, but they can be useful for any process improvement initiative. We’ll explain the key SIPOC components and demonstrate how to build one. Then, we’ll walk through a few scenarios and let you build your own.

Learners follow design steps incorporating a bleed, a technique used to allow for inaccuracies in the printing and trimming processes.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

In this learning activity you'll explore how computers connected on a network use Ethernet technology.

The learner examines what it means to listen respectively and how to become a better listener.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.
