Algorithms basics

The most correct definition of algorithm is...

• A computer program.

• A set of instructions that follow a specific order to solve a problem.

• Instructions that are followed representing an action.

• A secret code

Complete the sentence: "A good algorithm is easy to ________ and solves the problem ________."

• follow - clear

• understand - clear

• understand - effectively

• present - quickly

The IPO model stands for Input, Process, Output. Which of the following examples correctly represents the IPO model?

• Buying ice cream.

• Playing soccer.

• Taking with a friend.

• Baking a cake: ingredients, mixing and baking, baked cake.

Why are algorithms important in problem-solving?

• They help computers run faster.

• They make problems easier to understand and solve step by step.

• They create fun games.

• They present posible solutions to existing problems.

In the IPO model, what is the "Input"?

• The process that converts data into information.

• The step where we analyze the problem and present an alternative.

• The final result of the process.

• The data we enter into the system or process.

Imagine you are planning your day. How would an algorithm help you stay organized?

• By helping you follow a sequence of tasks step by step, so you don't forget anything.

• By giving you a list of random activities.

• By automatically completing your chores.

• By presenting different alternatives to show one of them.

What is pseudocode?

• A computer program.

• A real programming language.

• A way to write the steps of an algorithm using simple words.

• A way to draw an algorithm.

Why should we learn to create algorithms?

• So we can teach computers how to do everything.

• Because it helps us organize our thoughts and solve problems better.

• To become a famous programmer.

• To learn how to use a programming language more effective.

What is the purpose of a flowchart?

• To draw a pretty picture.

• To show the code of a program.

• To show the flow of an algorithm using symbols and arrows.

• To organize a problem using some symbols.

What symbol is usually used to represent "input/output" in a flowchart?

• A paralelogram.

• An oval.

• A rectangle.

• A diamond.
