4) Detailed design, Conceptual design, High-level design, Low-level design, Architectural design

Answer 1

The levels of software design are: Conceptual design, Architectural design, Detailed design, Low-level design, High-level design.

Step-by-step explanation:

The correct answer is Option 4) Detailed design, Conceptual design, High-level design, Low-level design, Architectural design.

The levels of software design can vary depending on different sources and perspectives. However, in the context of software development, the general sequence of design levels is as follows:

1. Conceptual design: This is the first level of software design, where high-level ideas, requirements, and goals are discussed and defined. It involves identifying the purpose, functionality, and overall principles of the software.
2. Architectural design: In this phase, the software's overall structure and components are planned. It focuses on defining the main modules, their interactions, and the overall organization of the software.
3. Detailed design: This level involves the actual coding and implementation of the software. It includes defining the algorithms, data structures, and other implementation details.
4. Low-level design: At this stage, the design is focused on specific modules or components of the software. It includes detailed specifications, interfaces, and internal workings of individual parts of the software.
5. High-level design: This is the final level of software design, where the focus is on the overall architecture and integration of different modules and components. It ensures that the software as a whole functions properly and meets the requirements set in the conceptual design phase.

These levels of software design are iterative, and there can be overlap and feedback between them. The goal is to gradually refine the design, ensuring that each level builds upon the previous one and leads to a well-structured and functional software.
