Unit 1 (Computing Systems), Chapter 1: What is Computer Science?

What is a group of connected computers called?

A network, or a computer network.

What is a program, and why do computers need programs?

A program is a set of instructions that has been coded into a language that a computer can understand. Without programs, computers wouldn't understand what we want them to do.

Explain what an algorithm is.

What is computer science?

Computer science is the stidy of using computers to solve problems.

What is a computing system? Provide examples of computing systems.

Computing systems are one or more computing devices. They include laptops, tablets, and other devices that are run by programs.

What is the difference between a consumer and a creator?

Consumers only use programs or contents. Creators make the content that consumers use.

Reviewing a collection of student score from an exam to understand how well the class did is an example of which concept area of computer science?

Data and analysis.

Computer scientists have created systems that help farmers produce more food for society. This advancement most closely represents which of the five concept areas of computer science?

Impacts of computing. While each of the five concept areas of computer science are used to develop better tools for farmers, the emphasis on how it benefits society makes this an example of impacts of computing.
