Programming Concepts Quiz

A decision tree includes decisions where the tree splits into two branches. What program structure matches this part of a decision tree?

• Loop

• Sequence

• Selection (Conditional)

• Iteration

Supposing a scientist sent a signal with the symbol # in it. Would the decision tree classify this as a good or bad signal?

• Good signal

• Bad signal

• Neutral signal

• Undefined

Which of the following best describes why a program might include a loop?

• To make a single decision.

• To repeat a set of instructions multiple times.

• To display a message once.

• To store a single value.

What is the primary purpose of the "append" command in a programming context?

• To remove an item from a list.

• To add an item to the end of a list.

• To sort the items in a list.

• To replace an item in a list.

What does machine learning mean?

• A programming technique that requires explicit instructions for every task.

• A field of computer science that enables computers to learn from data without explicit programming.

• A method for manually organizing large datasets.

• A software application that performs repetitive calculations.

State one advantage to Taz of using machine learning to spot bad signals.

• Increased manual labor for signal analysis.

• Faster and more automated identification of bad signals.

• Reduced data storage capacity.

• Elimination of all signal data.

In both supervised and unsupervised training, the computer gets lots of data. What is the difference between the two?

• Supervised learning uses labeled data, while unsupervised learning uses unlabeled data.

• Unsupervised learning requires human intervention, while supervised learning does not.

• Supervised learning focuses on classification, while unsupervised learning focuses on regression.

• There is no significant difference between the two.

What type of computer system is needed for deep learning?

• A standard office computer with basic software.

• A network of interconnected personal computers.

• A high-performance computing system with powerful processors (GPUs/TPUs).

• A calculator with advanced functions.

This program loops 100 times. How would you change the program to loop fewer times?

• Increase the loop counter to a higher number.

• Decrease the loop counter to a lower number.

• Remove the loop entirely.

• Add more code inside the loop.

Which line of the program gets feedback from the user?

• The line that initializes variables.

• The line that performs calculations.

• The line that prompts the user for input.

• The line that prints output to the console.
