a) What is scheduling? Explain four design characteristics that can enhance the scheduler's performance?

b) How can buffering improve the performance of a Computer system? and I/O operations. In other cases, buffering scheme may not work well

C) From the paper Micro-kernel Architecture Key to Modern Operating Systems Design by

Michel Gien (1990):

i) Why does the author vouch for the microkernel architecture

ii) Why Does use of microkernel architecture make the software adapt to software engineering practices?

D) Explain the Producer-Consumer problem and how semaphores help to solve the problem
