CSE Unit 1 Terms

TermDefinition
Variable 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.
String Text or characters displayed by a program. In MIT App Inventor block mode, a text block lets you manage how text or “strings” will be presented to the user of an app.
Float A type of number that provides very precise information by including all the numbers after the decimal.
Integer A whole number that does not have a decimal or any digits after the decimal.
Boolean A data type that only has two values, usually denoted as true or false.
Argument 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.
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!”
Logical Operators Conditional statements (True, False).
Relational Operators < (less than), > (greater than), = (equals)
Arithmetic Operators The same ones you use in math class such as + (addition), – (subtraction), x (multiplication), and ÷ (division).
Debugging To identify errors or bugs in computer hardware or programs and fix them.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
