| stack | is an area of RAM memory during the running of a program where variables/properties that have a very short lifespan are stored; the only things that are stored here are primitive properties, like an int, that are declared inside of a method |
| property declaration | is when a property is announced; properties have to be preceded with their data type such as int, char or an object data type like Car |
| method declaration | is when a function is announced and defined; it always has to have a return type announced and parentheses after the name of the function with any parameter types it will take indicated in them |
| heap | is an area of RAM memory where longer term properties and object instances are stored; all global properties are stored here because they are associated with the object overall; and any object properties declared inside a method are also stored here |

| List < > carlist = new List< > ( ) ; | the < > tags are used to tell what data type should go into a List object in C# and an ArrayList in Java; they hold ANY type of data but when you use these tags they can be created to hold only a single type; this is called parameterizing a generic type |
| protected | this access modifier allows properties to be accessed by the class that the property is declared in AND any class that is derived (a child class of) from that class |
| LinkedList | is a class of objects in C# (an ArrayList in Java) that contains nodes (instead of elements like in an Array); the nodes contain a pointer to the next node in the list as well as one to the previous node; they are not limited to any small amount like 500 |
