Consider the following process model with two suspend states. (a) Briefly describe the Blocked and Ready/suspend states. (b) Give an example on each transition of state from Running state to Blocked state and then to Blocked/suspend state. (c) Why are two modes (user and kernel) needed in modern operating system? (d) Consider a computer with N processors in a multiprocessor configuration. (i) How many processes can be executed in each of the Ready, Running, and Blocked states at one time? Justify your answer. (ii) What is the minimum number of processes that can be executed in each of the Ready, Running, and Blocked states at one time? Justify your
