true or false all of them

6. The four components managed by an OS are Main Memory, System Bus, Processor (CPU),
and I/O Modules.

7.Every (Unix or Linux) process has its own unique PID (process ID).

8. Two different (Unix or Linux) processes can have the same PID.

9. Two different (Unix or Linux) processes can have the same PPID (parent process ID).

10. Process management code in the kernel is always executed in kernel mode.

Expert Solution

6. True,The four components managed by an OS are Main Memory, System Bus, Processor (CPU),
and I/O Modules. Some important functions of Operating Systems:

Memory Management
Processor Management
Device Management
File Management
Security and I/O Modules

7. True,Every (Unix or Linux) process has its own unique PID (process ID) because operating system tracks processes through this 5 digit ID number , Process ID or PID.

8. False,Two different (Unix or Linux) processes can not have the same PID because at any point of time, Unix uses PID to track each process in the system.

9. True, Two different (Unix or Linux) processes can have the same PPID (parent process ID) as it tells which process has started the main process and a process can have many number of child processes.

10. True, Process management code in the kernel is always executed in kernel mode, as Process management involves different tasks like creation of Processes, scheduling of Processes, termination of processes, and a dead lock detection and Kernel mode is reserved for such trusted functions and low-level functions of OS, on the other hand, It can also execute any CPU instructions and can provide reference to any memory address in system successfully.

True or false 1) OS uses multiple queues in process scheduling. At any time instance, the PCB of a process can only belong to one queue. 2)OS uses the \proc pseudo-file system to store the statistical information of a process. Even if a process is terminated, we can still find the statistical information on of this process from the \proc pseudo-file system. 3) When a process successfully calls an exec*() function to run a program, the executed program will inherit...
