Topic-7 Process

Process is basically a program code in execution. Program and process are two different things.

As the process executes, it changes its state from one to another.
Its state can also be called as the current status as it shows the current activity of that process.

These state may be :
1. New : The process is being created
2. Running: The commands (instructions) are being executed.
3. Waiting: The process is in waiting due to some event.
4. Ready: The process is assigned to a process.
5. Terminated: The process has finished execution.

The above diagram shows the process state.
