This unit reveals how the Internet was designed to connect billions of devices and people to one another. Learn how the different protocols of the Internet work and actually build them yourself using the Internet Simulator. Then consider the impacts the Internet has had, both good and bad, on modern life.
Students will be able to:
Identify questions they have about how the Internet works
Use the Internet Simulator to communicate information with a partner
Students will be able to:
Identify the path(s) connecting two devices in a simulated network
Explain how computing devices can be connected to form a network
Students will be able to:
Explain the need for open and shared protocols for communicating on the Internet
Describe the way the Internet Protocol helps uniquely identify one another on the Internet
Students will be able to:
Explain how data is routed through the Internet
Describe how the redundant nature of networks can lead to dynamic, fault tolerant routes
Students will be able to:
Describe how information flows through the Internet as a datastream of packets
Explain how packet numbering and re-ordering can allow for large messages to reliably be sent even if packets are dropped or arrive out of order
Explain the differences between the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP)
Students will be able to:
Describe how HTTP is used for sharing the files and pages that make up the World Wide Web
Describe how the Domain Name System helps the Internet scale by allowing devices to find the IP addresses associated with a domain name
Explain how different layers of protocols on the Internet build upon and rely on one another
Students will be able to:
Identify how an internet dilemma has the potential to benefit and harm different stakeholders
Identify the ways the technical structure and design of the Internet contributes to a social dilemma
