What defines an all-in-one (AIO) computer?

An all-in-one (AIO) computer is defined by the integration of various components into a single unit. This means that it contains not only the processor and memory, but also the monitor all within one cohesive system. The benefit of this design is that it saves space and reduces cable clutter since multiple components are housed together.

This is in contrast to traditional desktop setups, where the monitor is a separate piece of hardware from the central processing unit (CPU). AIO computers typically offer a sleeker aesthetic and are more convenient for users looking for simplicity and efficiency in their workspace. Thus, option C accurately captures the essence and defining characteristic of an all-in-one computer.
