T-Level DPDD: Algorithms Quiz

What is an algorithm defined as?

• A plan or a well-defined set of step-by-step instructions to solve a problem.

• A complex mathematical formula.

• A random sequence of steps.

• A programming language.

Which of the following is NOT an advantage of algorithms?

• They are easy to understand by anyone.

• They are a step-by-step representation of a solution to a given problem.

• The initial problem is broken down into steps.

• They are always language dependent.

What is one disadvantage of algorithms?

• They are easy to understand.

• They are time-consuming to create.

• They are always language dependent.

• They are always simple and generic.

Which of the following is an advantage of flowcharts?

• The flow of the program can be seen clearly.

• They are always easy to follow.

• They do not require any symbols.

• They are always simple and generic.

What is a flowchart?

• A graphical diagram that represents an algorithm which can be used to solve a problem.

• A written description of a problem.

• A set of programming codes.

• A mathematical equation.

What is a disadvantage of flowcharts?

• They are always easy to follow.

• They do not require any symbols.

• With a large, complicated program the flowchart can become very large and difficult to follow.

• They are always simple and generic.

What is a written description in the context of algorithms?

• A natural language or plain English language description of an algorithm.

• A graphical representation of an algorithm.

• A set of programming codes.

• A mathematical equation.

What is one advantage of using a written description in programming?

• It has a formal syntax.

• It is automatic and natural to use 'proper' English.

• It requires specialized knowledge.

• It includes every step required.

What is one disadvantage of using a written description in programming?

• It is easy to include every step required.

• It has a formal syntax.

• It may fail to include every step required.

• It is difficult to understand.

What is pseudocode?

• A formal programming language.

• A high-level programming language.

• An informal programming description showing the flow through the process.

• A type of program code.
