Which of the following refers to the physical components of a computer?

The term that refers to the physical components of a computer is hardware. Hardware encompasses all the tangible parts of a computer system, including the central processing unit (CPU), memory devices, storage drives, and peripheral devices like monitors, keyboards, and printers. These components are essential for the operation of a computer, as they provide the necessary infrastructure for running software applications and performing various tasks.

In contrast, the other terms listed have different meanings. Software refers to the programs and operating systems that run on the hardware, enabling the user to perform tasks and operate the computer. The network involves the systems and connections that allow devices to communicate with one another, often using cables or wireless signals. The cloud refers to remote servers and storage systems where data and applications can be accessed over the internet, rather than residing entirely on a local device. Understanding these distinctions clarifies why hardware is specifically identified as the physical aspect of computing.
