The programmer role is to focus on the problem that program has to solve. The programmer can allow to automatically exploiting parallelism inherent to the computation expressed by some other. Exercise 7. The mutual exclusion is necessary for multiprogramming systems because it will make that one process may update a shared resources at a time to ensure correct operation and results. Also because if two or more process used the same source or date one or more tasks can be waiting lifetime for completing their task which is called starvation, so mutual exclusion helps to avoid

Unformatted text preview: deadlocks in systems. Exercise 9. The buffer’s purpose is to provide a continuous flow of streaming date no matter how fast is system and connection the buffer helps to get clean and uninterrupted working of task. Example from my experience is for example many of different websites alike YouTube where they buffered the movie or music so when the movie is played is not going to stop or cut of all the time. Exercise 10. a) G=(A+C 2 ) * (E-1) 3 / D + B T1 = C*C T2 = E-1 T3 = A+ T1 T4 = T2*T2*T2 T5 = T3*T4 T6 = T5/D T7 = T6+B b) T1 = 3*3 T2 = 5-1 T3 = 5+9 T4 = 4*4*4 T5 = 14*64 T6= 896/8 T7 = 112+10 ANS = 122...
