Unshielded Twisted Pair Cables
In this learning activity you'll identify various types of unshielded twisted pair cables and their networking connectors.
Understanding Cloud Service Types
By Jeff Sonnleitner
You'll explore the three main services of cloud computing: Software as a service, Platform as a Service, and Infrastructure as a Service.
Twisted Pair Cable Noise Immunity
In this learning activity you'll explore how to reduce electromagnetic interference (EMI) and crosstalk between adjacent wires.
The IP Address Format
In this learning activity you'll examine the format of an IP address and interpret the octet by converting between decimal and binary numbers.
The Ethernet Frame
Learners view the seven segments of an Ethernet frame and the types of information each represents.
Switches and Hubs
Learners view animations showing how hubs and switches work in local area network configurations.
Subtracting Binary Numbers by Adding the 2's Complement
By Kevin Ritzman
In this learning activity you'll solve three binary subtraction problems using the 2's complement method.
STP - The Spanning Tree Protocol
By Dawn Rohm
In this learning activity you'll use the Spanning Tree Protocol to correctly set up a loop-free Ethernet local area network.
SSH - Secure Shell
In this activity you will learn the benefits of SSH, Secure shell, versus plain FTP.
Setting Up Your Virtual Private Network (VPN)
The learner will understand how to set up a Virtual Private Network (VPN) using a home computer network.
By Joseph Wetzel, Jeff Sonnleitner
In this interactive activity, learners insert the router terms that each acronym stands for. Each of the acronyms is formed from the key letters in a term that relates to routers.
In this learning activity you'll examine how routers transfer data between local area networks and the Internet.
In this learning activity you'll identify TCP and UDP port states and how they behave during interaction.
Port Scanning - Common Network Protocols
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 explore how port scanning is commonly used by hackers to infiltrate a network and how IT security professionals can detect it.
Peer-to-Peer Operating Systems
In this learning activity you'll examine how computers operate in a peer-to-peer network operating system.
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.
Network Internet Protocol (IPv6)
By Brett Sheleski, Terry Bartelt
In this learning activity you'll explore the IPv4 IP address scheme and the planned conversion to IPv6.
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.
Man in the Middle Attacks with ARP Poisoning
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 routers use routing tables to move data packets from their origin to their destination.
IP Addressing and Subnetting
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.
How the Ethernet Works
In this learning activity you'll explore how computers connected on a network use Ethernet technology.
