When implementing a solution to a problem， which of the following is the BEST course of action totake？（）
A: Replace all components simultaneously to ensure that the system is functional.
B: Replace all hardware associated with the problem first to eliminate the possibility of hardware and move onto software.
C: Purchase new parts for the system to confirm that they function.
D: Implement one change at a time， reversing the change if it has not resolved the problem.

举一反三
- A step-by-step solution to a problem is called( ). A: hardware B: an operating system C: a computer language D: an algorithm
- The single objective optimization problem assumes that the objective function f (x) is a scalar function. When the objective function is extended to a vector function, the optimization problem is transformed into a multi-objective optimization problem. ( )
- One of the objectives of CNC systems is to replace as much of the conventional NC hardware with software as possible.
- A computer system consists of hardware system and software system.
- The kernel is defined as: A: The graphical user interface on top of the operating system B: The glue between the hardware and applications C: The software libraries needed to run the system D: All of the above
