Which system design focuses on the implementation details such as hardware and software?

The concept of physical design in system development emphasizes the specific implementation details required for the system to function effectively. This includes the selection of hardware, software, networking components, and other technologies necessary for the system's operation. During the physical design phase, system architects and designers translate the requirements defined during earlier stages, notably logical design, into detailed specifications that inform the actual construction of the system.

Physical design is critical as it ensures that all components work together seamlessly and that the system meets performance, reliability, and usability goals. Decisions made in this phase impact the overall effectiveness of the system and its ability to fulfill the needs identified earlier in the design process.

In contrast, logical design focuses more on the abstract relationships and requirements of the data without getting into specific implementation details, while data design deals specifically with how data will be handled within the system. Conceptual design outlines the high-level view of the system, including its overall structure and framework.
