computer architecture | The logical structure and functional characteristics of a computer, including the interrelationships among its hardware and software components. |
computer program | A sequence of instructions suitable for processing by a computer. |
constructor method | A method with the same name as the class that initializes the instance variables of an object of the class when the object is instantiated. |
