Question $1$

$1\mathrm{.}1$ Software systems engineering refers to the systems application of principles to the software engineering discipline. In complex systems, it is absolutely essential to partition them into relatively independent subsystems that may be designed, developed, produced, and tested as separate system building blocks, and similarly to subdivide the subsystems into relatively self$-$contained components. This approach handles system complexity by segregating groups of mutually interdependent elements and highlighting their interfaces. Identify a system of your choice. Draw a functional flow block diagram $($FFBD$)$ for this system. Describe each function for the system.
