Flashcard on Computational Thinking

Front

Decomposition in computational thinking

Back

Breaking down a problem into smaller, manageable parts

Answer explanation

In computational thinking, 'Decomposition' refers to breaking down a problem into smaller, manageable parts. This approach makes complex problems easier to understand and solve, which is why this choice is correct.

Front

Abstraction

Back

Focusing only on the essential details of a problem

Answer explanation

Abstraction involves focusing only on the essential details of a problem while ignoring the irrelevant aspects. This helps simplify complex systems and makes it easier to manage and understand them.

Front

What is an algorithm?

Back

A set of instructions to solve a problem

Answer explanation

An algorithm is best defined as a set of instructions to solve a problem. While a computer program implements algorithms, the essence of an algorithm lies in its step-by-step approach to problem-solving.

Front

What is the purpose of a flowchart?

Back

To visually represent the steps of an algorithm

Answer explanation

A flowchart is used to visually represent the steps of an algorithm, making it easier to understand the process and flow of information. This helps in planning, analyzing, and communicating the logic of a program.

Front

Which symbol is used for a process in a flowchart?

Back

Rectangle

Answer explanation

In a flowchart, a rectangle symbolizes a process or operation. It is used to represent actions or tasks, while other shapes like diamonds indicate decisions and ovals represent start or end points.

Front

Which symbol represents a decision in a flowchart?

Back

Diamond

Answer explanation

In a flowchart, a decision is represented by a diamond shape. This symbol indicates a point where a choice must be made, leading to different paths based on the outcome, unlike ovals, rectangles, or parallelograms which represent other functions.

Front

What does "sequence" mean in a flowchart?

Back

Executing instructions in order, one after the other

Answer explanation

In a flowchart, 'sequence' refers to executing instructions in a specific order, one after the other. This ensures that each step is completed before moving to the next, which is essential for the flow of the process.

Front

What does "iteration" represent in a flowchart?

Back

Repeating a block of instructions

Answer explanation

In a flowchart, "iteration" refers to the process of repeating a block of instructions. This allows for tasks to be executed multiple times until a certain condition is met, making it essential for loops in programming.

Front

Which Python statement is used to display output?

Back

print()

Answer explanation

The correct statement to display output in Python is 'print()'. The other options, 'input()', 'output()', and 'display()', do not serve this purpose. 'print()' is specifically designed to output data to the console.

Front

How do you receive input from the user in Python? Options: input(), print(), receive(), get()

Back

input()

Answer explanation

In Python, the correct way to receive input from the user is by using the input() function. The print() function is used to display output, while receive() and get() are not standard Python functions for user input.
