Answer:
D. Hardware.
Step-by-step explanation:
The five-component model of a computer system is a conceptual model that describes the five main components of a computer system: hardware, software, data, procedures, and people.
Hardware refers to the physical components of a computer system, including the central processing unit (CPU), memory, storage, and input/output devices. Hardware is the easiest component of the five-component model to change, as it can be upgraded or replaced as needed.
Software refers to the programs and applications that run on a computer system. Software is relatively more complex to change than hardware as it requires specialized skills and knowledge.
Procedures refer to the standard operating procedures and processes that are used to operate and maintain a computer system. Procedures are relatively more complex to change than hardware as it requires specialized skills and knowledge.
Data refers to the information that is stored on a computer system. Changing data requires a more complex process than changing hardware.
People refer to the users, operators, and administrators of a computer system. Changing people's behavior and knowledge is relatively more complex than changing hardware
