What is a key feature of a microprocessor?

A key feature of a microprocessor is its ability to perform computations and processing tasks, making it central to the functionality of computers and many electronic devices. Microprocessors execute instructions from software, which involves carrying out arithmetic calculations, logical operations, and data manipulation. This capability allows them to support a wide range of applications, from simple calculations to complex processing required in graphical systems, data analysis, and multitasking.

The correct understanding of this function highlights why this option is the most accurate representation of what a microprocessor does. In contrast, other choices misrepresent the core functionalities of microprocessors. For instance, data storage is not the primary function of a microprocessor; instead, it often works in tandem with memory components that handle storage. Furthermore, microprocessors definitely run software programs, as they are designed for executing instructions specified in those programs. Lastly, while power needs can vary among different microprocessor designs, the requirement for multiple power sources is not a defining characteristic of microprocessors themselves, as many can operate efficiently on a single power source.
