Which component is not considered a core hardware part of a computer?

The correct choice indicates that word processing software is not considered a core hardware part of a computer. In the context of computing, core hardware components typically include physical devices such as the central processing unit (CPU), random access memory (RAM), and input devices like a keyboard or mouse.

Software, like word processing applications, runs on the hardware but is fundamentally different from hardware in that it consists of code and data that instruct the computer on how to perform various tasks. Core hardware refers to the physical elements necessary for a computer system to function, while software applications, including word processors, are programs designed to perform specific operations for the user. Therefore, word processing software does not fall into the category of hardware components necessary for the basic operation of a computer.
