    In public key cryptography, the sender uses the recipient's public key to encrypt a message. Which of the following is needed to decrypt the message? What is the "key" to a Caesar Cipher that someone needs to know or discover to decrypt the message? Which of the following is the most accurate description of what is known as the "digital divide". The digital divide is about how Public key encryption is an encryption method which relies on separate keys for encrypting and decrypting information. Public key encryption is a highly secure encryption scheme that in which a single shared key is used by both the sender and receiver of the message.

    Public key encryption makes use of certain types of problems which are easier for humans to solve than computers. Public key encryption makes use of mathematical problems which no algorithm can be used to solve.

    A coffee shop is considering accepting orders and payments through their phone app and have decided to use public key encryption to encrypt their customers' credit card information.

    Is this a secure form of payment? No, the internet protocols are open standards and thus everything sent over the internet is sent "in the clear". Yes, public key encryption is built upon computationally hard problems that even powerful computers cannot easily solve. Pick the two expressions involving the Modulo operation that compute to the exact same value choose 2. A programmer is writing a system that is intended to be able to store large amounts of personal data.

    As the programmer develops the data system, which of the following is LEAST likely to impact the programmer's choices in designing the structure of the system? A coordinated effort by a group to simultaneously attempt to gain entry to foreign government's servers or systems. An effort by network engineers to focus all systems on catching a user or computer that has illegally gained access. You accidentally run a piece of code that automatically spreads from one computer to another, exploiting a common vulnerability.

    What is this website potentially useful for? What kinds of problems could the provided information be used to solve? Is the provided visualization useful? Does it provide insight into the data? How does it help you look at a lot of information at once? How could it improve? Where is the data coming from? You may also need to do a web search. Is the data from one source or many?

    Is it static or live? Is the source reputable? Why or why not? Add a link to the raw data if you can find one. Explain your reasoning.

    Unit 4 Lesson Activity Guide - Research Yourself. Suppose someone were to research you online. What would they be able to find? What connections could they make from the existing data out there to learn even more about you? You should look through any publicly available pieces of information online.

    Start by simply looking up your name in a search engine but then refine your results by adding more specific information, like the place you live. In the space below record the information you find about yourself. If you need more space, you can record your findings on the back of this sheet as well. Where you found it. Now connect the dots. If someone really wanted to find out about you online, given the information above, what would they know about you?

    Of the pieces of information you found above, which do you think poses the biggest threat to your security or privacy? Why do you think so? Goals :. Understand how the Vigenere Cipher Algorithm works. Figure out what makes for a good v. Instructions :. You should have a partner for this exploration.

    Your textbook will be online. There will be simulations, widgets, and videos, as well as assessments and frequent vocabulary tests. Timeline may be adjusted as we work through the course.

    The unit then explores the structure and design of the internet and the implications of those design decisions. Being able to digitally manipulate data, visualize it, and identify patterns, trends and possible meanings are important practical skills that computer scientists do every day. Understanding where data comes from, having intuitions about what could be learned or extracted from it, and being able to use computational tools to manipulate data and communicate about it are the primary skills addressed in the unit.

    This course uses JavaScript as the programming language, and App Lab as the programming environment to build apps, but the concepts learned in these lessons span all programming languages and tools. The goals of this unit are to develop a well-rounded and balanced view about data in the world, including the positive and negative effects of it, and to understand the basics of how and why modern encryption works.

    Student Prerequisites. The course introduces students to the creative aspects of programming, abstractions, algorithms, large data sets, the Internet, cybersecurity, and how computing impacts our world. Students will develop the computational thinking skills needed to fully exploit the power of digital technology and help build a strong foundation in core programming and problem-solving. Curriculum The year-long course consists of seven units, carefully structured to guide novice students through the study of computational technology.

    Each unit is sequenced to first establish a context for course material, then teaching the core skills for creating and using computational tools, followed by demonstrating real-world applications of digital technology, and finally allowing students to exhibit skills they have developed.

    Term 1. In Term 1, students will learn core computational thinking skills and explore the vital role of information in computing and how data can be codified, expressed, stored, and manipulated. Term 2. In Term 2, students will further explore how digital computing revolutionizes industries and enables new forms of expression, communication, and discovery.

Trace the code and plot the movements of the robot for the 3 scenarios shown to the right of the code. There are a few patterns to the ways if-statements are typically used:. Basic If-statements. Sequential If-statements. Basic If-else statements.

    Nested If and if-else statements.

    Combinations of all of the above. Each section below presents an example of one of these common patterns, followed by a few problems for you to try. For each type study, and make sure you understand, the example and why each of the 3 scenarios ends up in the state shown. Code is executed sequentially from top to bottom. The code inside the if-block executes ONLY if the condition is true, otherwise the block is skipped and execution picks up on the first line after the if-block.

    Scenario Use the diagram to trace each robot move. Lines of code, including if statements, are evaluated separately, one at a time, in order from top to bottom.

    An if-block executes ONLY if the expression is true. Note that an earlier if-statement might change the state of the of world for an if-statement that comes later. This makes it hard to predict what will happen unless you trace the robot moves and take each line one at a time. The code in the if-block executes ONLY if the expression is true, otherwise the code in the else block will run.

    But one or the other must execute. An else statement can be attached to a single if-statement. Here is a block-based. You can put if- and if-else statements inside other if-statements. All previous rules apply, but tracing the code can be tricky.K - University grade. Played times. Print Share Edit Delete. Live Game Live. Finish Editing. This quiz is incomplete!
