Understanding Computer Science Terms

What is the primary purpose of abstraction in computer science?

• To add complexity to a problem.

• To simplify a complex system by focusing on the essential details.

• To create a detailed representation of every component.

• To eliminate all forms of data representation.

Which of the following best describes accessibility in technology design?

• Designing products exclusively for tech-savvy users.

• Ensuring that products are usable by all people, including those with disabilities.

• Creating products that are only compatible with the latest devices.

• Focusing on aesthetics over functionality.

How does an algorithm differ from a simple list of instructions?

• An algorithm is a random sequence of steps.

• An algorithm is a structured set of steps designed to solve a specific problem.

• An algorithm is a type of computer hardware.

• An algorithm is a programming language.

In the context of computing, what does binary refer to?

• A system using multiple options for data representation.

• A method of representing data using only two states, typically 0 and 1.

• A language with a vast vocabulary.

• A type of software application.

What constitutes the binary alphabet?

• The letters A to Z.

What is the significance of a bit in computing?

• It is a large unit of data storage.

• It is the smallest unit of data in a computer, representing a binary value of 0 or 1.

• It is a type of programming error.

• It is a complex software application.

What distinguishes block-based programming languages from text-based ones?

• They use complex syntax and commands.

• They allow users to create programs by arranging visual blocks rather than writing text code.

• They are only used by professional developers.

• They are used for creating operating systems.

Which of the following is a characteristic of Blockly?

• It is a text-based programming language.

• It is a visual programming language that uses blocks to represent code.

• It is a type of computer hardware.

• It is a software for graphic design.

How does a bit differ from a byte in digital data?

• A bit is larger than a byte.

• A bit is the smallest unit of data, while a byte consists of 8 bits.

• A bit is used for text data, while a byte is used for images.

• A bit is a type of software application.

What is the role of an algorithm in problem-solving?

• To randomly guess solutions.

• To provide a systematic approach to solving a problem through a series of defined steps.

• To complicate the problem further.

• To eliminate the need for any logical reasoning.
