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

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 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 network address translation works.

In this learning activity, you'll examine the different ways in which computers and other equipment are physically connected in local area networks and the advantages and disadvantages of each topology.

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.

Fibre Channel storage area networks can play a pivotal role in the performance of cloud computing. This learning activity

will explain the benefits, components, and some basic configurations of fibre channel networks.

In this learning activity you'll explore how VPN is used to create a secure connection between two networks.

In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.

In this learning activity you'll explore the IPv4 IP address scheme and the planned conversion to IPv6.

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.

In this learning activity you'll use the Spanning Tree Protocol to correctly set up a loop-free Ethernet local area network.

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

Learners view animations showing how hubs and switches work in local area network configurations.

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

In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.

This interactive activity represents the grid modeling technique, a heuristic model for choosing a centralized location for a manufacturing or distribution center within a supply chain network. The formula calculates a central point between the suppliers and the markets. This object requires the latest version of Flash Player.

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

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

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