Essential Question: How does the Internet work?
Mastery Objectives:
SWBAT use technical terminology to describe how the Internet works.
SWBAT describe how packets are sent via protocols.
Directions: Create a slide show presentation that defines each vocabulary word in your own language and displays a picture of something that is not technology related that can be used to compare the vocabulary word. For instance, a picture of a brain could be used to explain how a computer works. Your final slides should be diagrams that help you describe how the Internet works. You will be graded on how well you are able to describe how it works and how well each of your group members are able to answer questions about the vocabulary words and how the Internet works. If you do not understand how the Internet works, you need to know how to explain it.
Ticket-to-Leave:
In the comments below, write one concept about the Internet that you are still struggling with.
In the comments below, write two vocab words you understand.
In the comments below, describe the video that best explains how the Internet works.
Requirements:
A slide show presentation created in Google Slides or Jamboard
1 slide for each vocabulary word with the definition below AND the definition in YOUR OWN WORDS.
1 slide for each vocabulary word with a nontechnical image to describe that vocabulary word.
2-3 slides to describe how the Internet works. You are not allowed to use a diagram from the Internet, all diagrams need to be created by your group.
A poster with a diagram of how the Internet works.
Vocabulary Words and Definitions:
IP Address - A number assigned to any item that is connected to the Internet
DNS (Domain Name Service) - The service that translates URLs to IP addresses
URL (Universal Resource Locator) - An easy-to-remember address for calling a web page (like www.code.org)
Internet - A group of computers and servers that are connected to each other
Servers - Computers that exist only to provide things to others
Cloud - Storing data in the cloud means storing it somewhere on the Internet
World Wide Web - the collection of interlinked website documents (such as HTML files) that you can view with a web browser by typing addresses like http://bjc.berkeley.edu/website/privacy.html.
Protocol - the standard for communication between browsers and servers (usually "http" or "https")
Domain Name - the name of the server that hosts the data
IP - (Internet Protocol) an addressing system that finds paths to distant computers and splits data into small packets sent separately
TCP - (Transmission Control Protocol), a reliable system of transmitting data packets
Bit - the smallest unit of data, which can only have one of two values (such as a 1 or 0).
Bandwidth - is the transmission capacity of a system (for digital data, it is measured by bit rate). Higher bandwidth is better; the data will travel more quickly.
Latency - time between the transmission and the receipt of a message. Lower latency is better; the data will take less time to start transmitting.
Redundant - here are multiple pathways among the physical connections of the Internet to create redundancy. Even if one pathway is unavailable, there is still another way to transmit a message from sender to receiver (as shown right).
Wi-Fi - A wireless method of sending information using radio waves
DSL/Cable - A method of sending information using telephone or television cables
Packets - Small chunks of information that have been carefully formed from larger chunks of information
