DEFINE: Computer Science

• Computer science is the study of processes that interact with data and that can be represented as data in the form of programs. It enables the use of algorithms to manipulate, store, and communicate digital information.

• A way of representing information using only two options.

• The visual programming language used in Code.org's online learning system for K-5 students.

• the study of the principles and use of computers.

Algorithm

• The most common fundamental unit of digital data .

• Getting help from a large group of people to finish something faster.

• A list of steps to finish a task.

Code

• Statements that only run under certain conditions.

• The language that programmers create and use to tell a computer what to do.

• Break a problem down into smaller pieces.

SERIES OF COMMANDS

• PROCESSING

• FUNCTION

• STORAGE

• ALGORITHM

A list of steps to finish a task. A set of instructions that can be performed with or without a computer. 

• recipe
• algorithm
• statement
• loop
