BTEC Unit 1 Revision Quiz 1

What is Computational thinking?

• A method of problem-solving that helps computer scientists prepare problems for digital solutions

• A type of software development

• A hardware troubleshooting technique

• A networking protocol

What are the 4 Computational thinking skills?

• Decomposition, Pattern Recognition, Abstraction, Algorithm Design

• Analysis, Design, Implementation, Testing

• Programming, Debugging, Analysis, Compilation

• Logic, Function, Recursion, Concurrency

The first stage of decomposition is identifying and describing problems and processes. What is the second? (Final stage)

• Developing solutions

• Implementing solutions

• Evaluating results

• Planning and designing

Which of the following are reasons why programmers use decomposition to solve problems?

• To simplify complex problems into manageable parts

• To increase the complexity of the code

• To improve collaboration among developers

• To reduce the efficiency of problem-solving

What are the 5 stages of pattern recognition?

• Signal reception, feature extraction, segmentation, matching, recognition

• Data collection, processing, analysis, interpretation, feedback

• Input, process, output, feedback, storage

• Observation, orientation, decision, action, feedback

Give one reason why a programmer would use pattern recognition to solve problems.

• To improve code efficiency

• To simplify complex problems

• To enhance problem-solving skills

• To reduce debugging time

Define what is meant by abstraction.

• A process of hiding the implementation details and showing only functionality.

• A method of organizing data in a database.

• A type of data structure.

• A programming language feature for error handling.

There are 6 parts of a programming problem that will be identified using pattern generalisation and abstraction. What are they?

• Variables, Constants, Key Pairs, Reference Points, Inputs, Outputs

• Variables, Classes, Key Pairs, Reference Points, Inputs, Outputs

• Variables, Constants, Key Processes, Reference Points, Inputs, Outputs

• Variables, Constants, Key Pairs, Relational Points, Inputs, Outputs

Why would a programmer use abstraction to solve a problem?

• To reduce complexity and increase efficiency

• To increase processing time

• To make the code more dependent on specific implementations

• To reduce the number of lines of code

What is an algorithm?

• A step-by-step procedure for calculations

• A type of computer hardware

• A programming language

• A data storage unit
