What term refers to the physical components of a computer system?

Software
Hardware
Network
Protocol

The correct answer is: Hardware

The term that refers to the physical components of a computer system is hardware. Hardware encompasses all the tangible elements that make up a computer, including the central processing unit (CPU), memory (RAM), storage devices (hard drives, SSDs), the motherboard, and peripheral devices such as keyboards, mice, and monitors. These components work together to perform computing tasks and run software, which consists of the programs and applications that instruct the hardware on what to do. In contrast, software involves the non-physical aspects of computing, such as operating systems, applications, and other programs that run on the hardware. A network refers to a collection of interconnected devices that can communicate with each other, while a protocol is a set of rules governing the communication between devices. These terms illustrate different aspects of computer systems but do not encompass the physical elements that hardware represents.
