Chapter $9$: Architectural Design $($Initial Design$)$

Architectural design is the initial design phase in software engineering where the structure of the system is planned. It involves creating a Structure Chart that shows the overall system structure, including modules and their interactions.

Explanation:

$-$ Structure Chart: This is a diagram that represents the system$$s modules and their relationships. It helps in visualizing the high$-$level design of the system. Each box in the chart represents a module, and lines or arrows indicate how modules interact with each other.

Chapter $10$: Component$-$Level Design $($Detailed Design$)$

Component$-$level design focuses on the details of individual components or modules. This stage translates the architectural design into more detailed plans for each part of the system.

$-$ Module Internals Design: Here, we dive into the specifics of each module, defining how they will be implemented.

$-$ PDL $($Program Design Language$)$: This is a pseudo$-$code or structured English used to describe the logic of the modules in detail.

$-$ FBD $($Function Block Diagram$)$: A graphical representation of functions and their interconnections, often used in control systems and automation.

$-$ N$-$S $($Nassi$-$Shneiderman Diagrams$)$: These diagrams represent the logic of the code using a structured format, useful for visualizing algorithms.

$-$ FC $($Flowcharts$)$: Flowcharts are diagrams that represent the flow of control or data through a system, showing the sequence of steps involved in a process.

give me exmples not just i want to see how problems are solved. Quick please $.$
