Flashcards

What is a sequence in computer science?

A sequence is a list of steps that are followed in order. In computer science, programmers use sequences to give instructions to computers in the correct order.

What is a repetition in computer science?

Repetitions are a way to repeat a set of instructions a certain number of times. In computer science, programmers use repetitions to make their code more efficient and shorter.

What is a selection in computer science?

A selection is a decision made by a program based on a certain condition. In computer science, programmers use selections to create different outcomes based on the input.

What are loops in computer science?

A loop is a programming structure that repeats a set of instructions a specified number of times. Programmers use loops to minimize code and make it more efficient by avoiding repetitive lines of code.
