Unit 2 Fundamentals of Computer Science Quiz

Benjamin, Priya, and Muhammad are studying computer architecture. They are discussing the difference between Harvard architecture and von Neumann architecture. Can you help them understand the difference?

• The way memory is organized

• The number of USB ports each architecture supports

• The operating system used by each architecture

• The color of the computer case used by each architecture

Poppy, Sophie, and Kiara are working on a group project to build a model of a computer. They are discussing the concept of pipelining in computer architecture. Can you explain how pipelining would help them in their project and its advantages?

• Pipelining would cause their resources to be underutilized and decrease the overall performance of their model.

• Pipelining would have no impact on their resources and would not affect the overall performance of their model.

• Pipelining would allow for better utilization of their resources and improve the overall performance of their model.

• Pipelining would only work for specific types of tasks and would not improve the overall performance of their model.

Arthur is using his computer to complete a project. He wonders what role the operating system plays in his computer system. Can you help him understand?

• It makes coffee for Arthur

• It plays music on Arthur's computer

• It manages Arthur's computer hardware and software resources

• It sends emails to Arthur's friends

Describe the difference between FAT32 and NTFS file systems.

• NTFS has a file size limit of 2GB and does not support file permissions

• FAT32 has a file size limit of 4GB and does not support file permissions, while NTFS has a much larger file size limit and supports file permissions and encryption.

• FAT32 has a file size limit of 10GB and supports file permissions

• FAT32 and NTFS have the same file size limit and support file permissions

What is RAID and how does it provide fault tolerance?

• RAID provides fault tolerance by encrypting the data to prevent failures

• It provides fault tolerance by using a single disk to store data, making it more susceptible to failures

• RAID does not provide fault tolerance, it is only used for increasing storage capacity

• It provides fault tolerance by using multiple disks to store data, allowing for data redundancy and/or parity to be used to recover from disk failures.

Explain the concept of RAID 5 and its advantages.

• RAID 5 is a data storage technique that uses block-level striping with distributed parity. It provides fault tolerance and increased performance.

• RAID 5 is a popular video game

• RAID 5 is a type of insect repellent

• RAID 5 is a cooking technique for making pasta

What is the role of a server in a computer network?

• Manages network resources

• Keeps the computer network clean

• Serves food to the computer users

• Plays music for the computer network

Differentiate between a web server and an application server.

• A web server handles HTTP requests and responses, while an application server executes the business logic and application code.

• A web server executes the business logic and application code, while an application server handles HTTP requests and responses.

• A web server is used for hosting websites, while an application server is used for hosting applications.

• A web server and an application server are the same thing.

What is data processing and why is it important in computer science?

• Data processing is the conversion of raw data into meaningful information. It is important in computer science because it allows for the manipulation, analysis, and interpretation of data to make informed decisions and solve complex problems.

• Data processing is the creation of raw data into meaningless information. It is important in computer science because it allows for the confusion, misinterpretation, and distortion of data to cause chaos.

• Data processing is the deletion of raw data into meaningless information. It is important in computer science because it allows for the loss, corruption, and misplacement of data to create confusion.

• Data processing is the transformation of raw data into irrelevant information. It is important in computer science because it allows for the stagnation, regression, and obstruction of data to hinder progress.

Describe the process of data mining and its applications in business.

• Data mining is the process of deleting unnecessary data from a database.

• Data mining is the process of creating new data from scratch.

• Data mining is the process of extracting minerals from the earth's surface.

• Data mining is the process of analyzing large sets of data to discover patterns and trends. Its applications in business include customer segmentation, market analysis, fraud detection, and predictive modeling.
