Physical components of a computing system, such as the central processing unit, memory modules, storage devices, and peripherals, represent the tangible elements one can see and touch. These components execute instructions. Conversely, the set of instructions that directs the physical elements to perform specific tasks is referred to as the non-tangible element. Examples of the former include keyboards and monitors; examples of the latter are operating systems and applications.
The interplay between the physical and the non-physical is fundamental to modern computing. The physical components provide the infrastructure, while the non-physical aspects dictate operations. Early computing relied heavily on specialized physical configurations for specific tasks. The advent of programmable systems allowed for greater flexibility, where the same physical infrastructure could perform diverse functions based on the non-physical instructions provided. This separation enables upgrades and modifications to either the physical elements or the controlling logic without necessarily requiring a complete system overhaul.
A deeper exploration into the architecture of computing systems will reveal the intricate relationships between these two fundamental aspects. Subsequent sections will examine specific examples of the physical elements and their logical control, demonstrating how they cooperate to achieve complex results.
1. Tangible versus intangible
The distinction between tangible and intangible elements is central to understanding computing systems.

These layers function collectively, ensuring effective interaction between the physical elements and user requests.
-
Interdependence for System Functionality
Effective system functionality relies on the synergistic interaction between physical and intangible components. Physical aspects without instructions are inert, while instructions without a physical platform cannot be executed. A computer requires physical memory to store executable instructions, and those instructions, in turn, instruct the physical CPU to process data. This circular relationship enables complete computing operations.
The interplay between tangible and intangible aspects defines the scope and capabilities of modern computing. Progress depends on developments in both domains. Advancements in physical components enable more powerful and efficient instruction processing, while new instructions allow for better utilization of physical resources and more advanced computations.
2. Physical components
