Embed: To insert Something usually in HTML

Algorithm: set of instructions that are followed to solve a problem

Argument: way to provide more information to a function. The function can then use that information as it runs, like a variable 

Array: containers that hold variables; they're used to group together similar variables. You can think of arrays like shelves at a pet store. The array would be the shelf, and the animals in cages are the variables inside. 

Arithmetic operators: essential in almost every application, especially in games. If a game character earns experience, it needs to be added to the total earned. If an arrow hits an enemy, the damage the enemy takes needs to be calculated.

Assignment operators:  (+=, -=, *=, /=) are operators that combine variable assignments (=) with arithmetic operators. They serve as a shortcut when coders have to perform an operation that changes the value of a variable. If a rock falls on a game player's head, health needs to be subtracted from their total, and so on.

Augmented reality: interactive experience where digital objects are placed in a real-world environment in real time. While virtual reality creates a completely artificial environment, augmented reality uses the existing real-world environment and overlays new information on top of it.

Autonomous

Autonomous robot, self-driving car, and delivery bot are all terms used to describe robots that navigate their environments using sensors with little to no human interaction.

Binary numbers

A binary number is a computer's way to represent information. Computers process millions of 1's and 0's a minute using different rules to interpret them as numbers, letters, operators, and everything else put into a computer.

Bit

The individual 1's and 0's you see in binary are called bits. 

Coding

Coding is how people create instructions for computers to follow. Just like people speak different languages, so do programs. For instance, Roblox uses the coding language Lua while Minecraft was built with Java. 

Coding languages 

Computers use coding languages to understand what people want them to do. Just like how people communicate with each other in English or Japanese, people communicate with computers in languages like C++ or Java. Some of the best coding languages for kids include JavaScript, Scratch, and Python.
