Answer: (C)

The hardware layer encompasses all the physical components of a computer system. This includes tangible parts such as the CPU, RAM, hard drives, motherboards, and any other electronic components that constitute the physical machine. Understanding this layer is fundamental in IT because it serves as the foundation upon which all software and applications operate. Unlike the other layers mentioned, which pertain to software and abstract functions, the hardware layer represents the actual equipment that processes data and runs applications. This distinction is essential for diagnosing hardware-related issues, performing upgrades, or assembling computer systems, making knowledge of the hardware layer vital for anyone pursuing a career in IT support.
