Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.

a. Draw four Gantt charts illustrating the
execution of these processes using FCFS,
SJF, a
non-preemptive priority (a smaller priority
number implies a higher priority), and RR
(quantum= 1) scheduling.
b. What is the turnaround time of each
process for each of the scheduling
algorithms in
