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 explore the IPv4 IP address scheme and the planned conversion to IPv6.

In this learning activity you'll examine the format of an IP address and interpret the octet by converting between decimal and binary numbers.

In this learning activity, you’ll explore how routers use routing tables to move data packets from their origin to their destination.

In this learning activity you'll explore the process that servers follow to take a name entered on a computer browser and convert it to an IP address.

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

In this learning activity you'll create a packet filter.

Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.

In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.

Learners click on the root word of a medical term in the left-hand column and drag it to its definition in the right-hand column. There is a time limit, so students will need to train themselves to recognize these root words quickly. Students may repeat the activity as often as they wish. A total of 74 terms are given in random order.

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.

Students look at the power dissipated by a single gate and by an IC. The concept of average current draw is introduced and examples are provided.

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

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

Instructors complete a simple, informal inventory that helps them to see how they use the Seven Principles of Good Practice in Undergraduate Education developed by Chickering and Gamson (supported by AAHE, ACE, Johnson and Lilly foundations) in 1987.

In this animated activity, learners examine the construction of a binary counter using a JK flip-flop. The ability of the JK flip-flop to "toggle" Q is also viewed.

Learners examine the correct method for calculating complex reciprocals. The solution for total impedance of a parallel circuit in rectangular form is shown.

In this learning object you'll review the basic quality principles of customers, suppliers, customer satisfaction, and customer expectations.

In this animated object, learners examine the recommended procedure for troubleshooting a defective JK flip-flop using a logic pulser and probe.
