L.O: STUDENTS WILL LEARN ABOUT THE INTERNET AND

ITS GLOBAL IMPACT.DO NOW:

What is “The Internet”?

The Internet is the global system of interconnected computer networks that use the Internet protocol suite (“IP addresses”) to link

devices worldwide.

The internet is a network of networks that consists of private, public, academic, business, and

government networks of local to global scope, linked by a broad array of electronic, wireless, and optical

networking technologies.

The internet is private computers linked to public computers linked to

college/university computers linked to business computers linked to government

computers….

In this unit:• We will learn the structure of the

internet.• We will learn about the protocols that

run the internet.• We will learn about the implications of

internet technology.• We will learn how the internet and its

systems have had a profound impact on society.

Also….• You will learn how the internet

operates.• You will study the characteristics of

the internet and the systems built on it.• Last, you will analyze concerns such

as cybersecurity

Our programming labs will focus on:Number Bases, Binary Data,

Network Protocols, Cybersecurity

This is 151

You will learn what this means

Note: • We will be seeing several videos from

code.org included in this unit. If you have difficulty accessing the videos, you can use this link:

• https://code.org/educate/resources/videos.

The Social Implications labs will focus on: Censorship and Computing around

the World

We will focus on Big Ideas 2 and 6.• The primary focus of this unit is the Internet (Big Idea 6).• Students learn about the power of the fundamental

abstractions (Big Idea 2) of the Internet including the two most essential protocols:

• IP, which builds one Internet out of a vast collection of local networks;

• and TCP, which allows the Internet to function reliably despite the lack of reliability of the physical infrastructure.

• You will also learn how the hierarchies of domain names and IP addresses make scalability possible.

Computational Thinking Practices P1, P3, P5, P6

You will learn to:• identify and describe the abstractions

(P3) of the Internet,• continue to collaborate (P6) as they pair

program, • and communicate (P5) as they connect

computing (P1) to society in the Social Implications labs.

Time permitting and also on your own we will watch several edX BJC Videos

The following are our student labs:

• Lab 1: Number Representation• 3-6 days (120-240 minutes) for required pages• Lab 2: Reliable Communication• 2-3 days (55-110 minutes) for required pages• Lab 3: Communication Protocols• 2-4 days (60-170 minutes)• Lab 4: Cybersecurity• 1-3 days (45-90 minutes) for required pages• Lab 5: Censorship and Computing around the World• 3-4 days (150-200 minutes)
