In this learning activity you'll observe how computers operate in a client-server network operating system and consider the advantages and disadvantages of such a system.
This animated lesson demonstrates hydraulic pressure switch applications when the switch is connected to a ladder circuit to operate in a hydraulic system.
In this animated activity, users examine the causes of malfunctions in a hydraulic pressure-reducing valve and the problems that result. A short quiz completes the learning object.
In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.
In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.
In this learning activity you'll explore how an Exclusive-OR gate operates by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
