1.3. The PCB is a data structure that stores essential information about a process: process identification, Process State Information, and Process Control Information. [10] (i) In your Linux machine, Linux VM, or sandcastle, run the following command: "ps aux". Provide the snapshot of what the command returns; just provide a few lines (10 lines of output). Through the snapshot, show the identification of five processes. Also, explain how you found the identification of these five processes. (ii) Use the same previous command (snapshot) and same list of processes you chose. Through the snapshot, show the state of the five processes. Also, explain how you found the state of these five processes. (iii) List and explain all the process states in Linux OS. Relate each of these Linux process state to the 7-state execution model we have seen in class. (iv) Choose one of the five processes you used in the previous answers. Find information about Process State and Process Control in "/proc/process_identification/". List what you found, explain what you found, and explain how you found it. Provide snapshots of the information you found. There is no need to be everything in the directory - that's too much. Provide information about status, memory, and scheduling of the process
