QUESTION 1
Explain steps that are to be taken by mangers of operating system to corporate with each other
Management process includes various tasks like creation, scheduling, termination of
processes and a dead lock. Process of this program has been executed and is an important part of
modern – day operating systems. This system must be allocated through enabling processes for
sharing and exchange information. Resources are also being protected of each process from
methods and allow synchronization among processes. It is the job of Operating system to
manage of all running processes of an system. Following are the steps to be taken by manger.
1. New: The new process is created when a specific program calls from secondary memory/
hard disk to primary memory/ RAM a
2. Ready: In a ready state, the process should be loaded into the primary memory, which is
ready for execution.
3. Waiting: The process is waiting for the allocation of CPU time and other resources for
execution.
4. Executing: The process is an execution state.
5. Blocked: It is a time interval when a process is waiting for an event like I/O operations to
complete.
6. Suspended: Suspended state defines the time when a process is ready for execution but
has not been placed in the ready queue by OS.
7. Terminated: Terminated state specifies the time when a process is terminated.
