**[CSE Lesson 1.1 Introduction to Computer Science Essentials]** **[Quiz Study Guide ]** **Activity 1.1.1 Getting Started with Block-based Programming** - **Activity 1.1.2 Algorithms and Coding Fundamentals** - **Variables - The smallest unit of data storage that a program can use. A variable contains known or unknown information referred to as a "value." Two types of variables are global and local.** **Arguments - The values that a program provides to a function or subroutine. Sometimes coding professionals use the terms "argument" and "parameter" interchangeably. In this course, argument is a better choice because *Python* does not use the term parameter.** **Data types -** **Integer - A whole number that does not have a decimal or any digits after the decimal.** **Float -A type of number that provides very precise information by including all the numbers after the decimal.** **Strings - Text or characters displayed by a program. In MIT App Inventor *Blocks* view, the text string block lets you manage how text, also known as strings, are seen by the user of an app.** **Boolean - A data type that only has two values, usually denoted as true or false.** **Concatenation A joining together of separate items---without changing them---into one place. For example, the concatenation of two strings such as "Hello" and "world!" would return "Hello world!"** **Arithmetic Operators - The same ones you use in math class such as + (addition), -- (subtraction), x (multiplication), and ÷ (division).** **Logical Operators - Conditional statements (True, False).** **Activity 1.1.3 Conditionals and Event Driven Programming** - **Conditional Statements - A programming statement that evaluates a true/false Boolean expression to determine the next steps in a program. Conditional statements are often written as \"if-then\" or \"if-then-else\" statements.** **Boolean Expressions A processing decision branch using relational operators (= ≠ \> \ \
