		The value stored in a variable determines that 
	
		variable's type 
	
		The type of a variable determines 
	
		• How the computer stores the data 
	
		• What operations can be done with it, and 
	
		how those operations work 
	
		• E.g. 4 + 5 returns 9 
	
		• E.g. "hello" + "world" returns 
	
		"helloworld" 
	
		Only so much you can do with basic data 
	
		types; most code we write will use data 
	
		structures 
	
		• containers that let you store multiple elements of a basic type 
	
		(or even of many basic types) in one variable
