An instance is a specific, live example of an object. For example, a file on my computer might be represented by an instance of a file object. An instance is contrasted with a class.
A method is code associated with an object which does something relevant to the object. For example, strings have a ToUpper() method which outputs the contents of the string as capital letters.
An object represents something like an integer, string, file, or anything else. It will have properties and methods.

Value refers to the current value of a property. For example, length might have a value of 10 which would mean the string has ten characters. If the number of characters changes then the value of the length property would change.
