Answer:

1/ Ensure data is clean and reliable

2/ Understand the contents of database

3/ Combine data from more than one source

Explanation:

I remember learning this in Computer class. If I am wrong, I am sorry; it has been a long time since I learned this!

When working with data from an external source, the metadata helps data analysts do is ensure data is clean and reliable, understand the contents of the database, and combine data from more than one source. The correct options are a, b and d.

Big Data can be meaningfully interpreted by analysts using metadata. The ability to identify, discover, and associate data throughout a business eventually raises the value of an organization's data resources.

Many types of Big Data are useless or difficult to manage without metadata. Understanding the structure, nature, and context of the data is made easier by the metadata.

Therefore, the correct options are

a. Ensure accurate and trustworthy data.

m comparators are required for an m-way set associate cache to locatre a block that has n words.

What exactly are comparators?

When two input voltages are compared, a comparator determines which is greater and outputs a binary signal.

              When the non-inverting (+) input exceeds the inverting (-) input, a high output is produced. The output becomes low if the inverting input exceeds the non-inverting.

Comparators belong to what class of circuit?

Two voltage values are compared by a voltage comparator circuit, and the results are output as an output.

                              One of two values is always the output (i.e., the output is digital). For illustration, let's say we have two A and B-labeled voltage comparator inputs.

The answers to the Introduction to Project Based Learning (PBL) is given below

To "fail forward" means to learn from mistakes and use those lessons to move forward and improve in the future. It means to see failure as an opportunity to grow and improve, rather than as a roadblock.

2. Employees in today's workplace are expected to have the skills of problem-solving and collaboration.

3. Project Based Learning (PBL) courses are typically taught by having students work on real-world projects that require them to apply their knowledge and skills to solve a problem or complete a task. The course content typically provides guidance and resources to help students complete the projects, but the students are responsible for managing their own learning and completing the projects independently.

4. Two examples of PBL projects might be designing a new app to help people track their fitness goals, or creating a marketing plan for a new product.

Question 5 is False. Every project will not follow the same format. PBL projects are flexible and allow students to design their own approaches to completing the project.

6. The entry event is the beginning of the PBL project, and it is designed to introduce the project challenge or problem that students will be working on. The purpose of the entry event is to engage students' curiosity and motivation, and to provide context and background information about the project.

7. In a PBL project, a student could play the role of a researcher, designer, developer, or project manager, among others.

8. The entry event is an important part of the PBL process because it sets the stage for the rest of the project and helps students understand what they will be working on and why it is important. It also helps students identify the knowledge and skills they will need to complete the project successfully.

11. Need-to-know-questions are questions that students need to answer in order to complete the PBL project successfully. These questions should be related to the project challenge or problem, and should be specific and focused.

13. The driving question is a central question that guides the PBL project and helps students focus their learning and problem-solving efforts. The driving question can be found in the entry event and in the project's final product or presentation.

14. Benchmarks are specific, measurable goals that students should aim to achieve as they work on the PBL project. They are used to track progress and ensure that students are on track to complete the project successfully.

16.. Examples of final PBL projects might include a prototype of a new product, a business plan, or a marketing campaign.

17.  PBL projects are typically graded based on the quality and completeness of the final product or presentation, as well as the student's effort and progress throughout the project.

18. The three parts of the PBL Project Rubric are content, process, and product. The content refers to the knowledge and skills that students demonstrate in the project, the process refers to the steps they took to complete the project, and the product refers to the final product or presentation.

19. Two success skills might be problem-solving and collaboration.

20. Sharing what you've learned is an important piece of the PBL process because it allows you to reflect on your learning and demonstrate your understanding to others. It also provides an opportunity for feedback and further learning.

21. The ability to analyze your work is an important piece of the PBL process because it helps you to reflect on your learning and understand what you have accomplished and what you still need to work on. By analyzing your work, you can identify your strengths and weaknesses, and make adjustments as needed to improve the quality of your final product or presentation.

22. Tallo is a career and educational platform that connects students with opportunities and resources related to their interests and goals. With Tallo, students can explore different career paths, find internships and job openings, connect with mentors, and access resources to help them plan for their future. Some examples of things that students can do with Tallo include creating a professional profile, applying for scholarships, and connecting with potential employers.
