Understanding Algorithms and Flowcharts

What is an algorithm?

• A random set of instructions

• A sequence of steps designed to perform a task

• A single step in a process

• A type of computer hardware

Which of the following is an example of an algorithm in everyday life?

• Reading a book

• Crossing a road safely

• Watching television

• Sleeping

What is pseudocode?

• A specific programming language

• A halfway between English language and actual programming code

• A type of flowchart

• A computer hardware component

What does a flowchart represent?

• A random collection of ideas

• A sequence of steps in an algorithm

• A type of computer program

• A mathematical equation

In a flowchart, what does a decision symbol represent?

• The start or end of a process

• The input and output of data

• A decision with yes or no outcomes

• A call to a subroutine

What is the purpose of refining an algorithm?

• To make it more complex

• To simplify it to a single step

• To improve its efficiency or adapt it for a new task

• To convert it into a different programming language

Which symbol in a flowchart represents the start or end of a process?

• Process symbol

• Decision symbol

• Terminal symbol

• Input/output symbol

How is pseudocode different from actual programming code?

• It follows a strict syntax

• It is more generic and not specific to any programming language

• It is written in binary

• It is only used for hardware design

What is the purpose of a line with an arrow in a flowchart?

• To represent a decision

• To show the flow of the algorithm

• To indicate a subroutine call

• To mark the start of a process

In the context of algorithms, what does the term "input" refer to?

• The final result of an algorithm

• Data that is processed by the algorithm

• The hardware used to run the algorithm

• The software environment for the algorithm
