Which layer is abstracted from the physical layer?

The logical layer is correctly identified as the layer that is abstracted from the physical layer. In networking and system architecture, abstraction refers to the concept of hiding the underlying complexities of a system, allowing users to interact with a simpler model.

The logical layer serves as an intermediary that provides a set of services and functionalities that do not necessarily relate to the physical components of the system. By abstracting away the details of the physical layer, the logical layer can focus on higher-level operations, data flow, and communication protocols, enabling developers and users to interact with the system without needing to understand the intricacies of the physical hardware involved.

Understanding this abstraction is crucial for designing scalable systems, as it allows for changes and improvements to be made to the physical infrastructure without impacting the services and functionalities at the logical layer. This separation fosters better modularity and system organization, making it easier to manage and update components of a network or architecture.

In contrast, the other layers mentioned, such as the physical network layer, cyber-persona layer, and data link layer, do not represent this level of abstraction from the physical layer. Each of these layers operates more closely with the physical components or serves specific functions that do not exemplify the same level of abstraction as the logical layer
