Final answer:
The UNIX SVR4 operating system recognizes a total of six process states: running, ready, blocked, suspended, zombie, and terminated.
Step-by-step explanation:
The UNIX SVR4 operating system recognizes a total of six process states. These process states include:
- Running: A process that is currently being executed by the CPU.
- Ready: A process that is waiting to be assigned to a CPU for execution.
- Blocked: A process that is waiting for an event to occur before it can continue executing.
- Suspended: A process that is temporarily stopped executing, but can be resumed later.
- Zombie: A process that has completed its execution but still has an entry in the process table.
- Terminated: A process that has finished executing and has been removed from the process table.
These process states are important for managing and scheduling processes in the operating system.
The UNIX System V Release 4 (SVR4) operating system recognizes a total of seven process states. These states help the system to manage processes efficiently and are essential for multitasking.
The process states recognized by UNIX SVR4 are: running, interruptible sleep, non-interruptible sleep, stopped, zombie, start/created, and exit. The running state is when the process is actively executing, while the interruptible and non-interruptible sleep states are for processes that are waiting for an event or resource.
A stopped process is one that has been paused, and a zombie process is one that has completed execution but still has an entry in the process table. The start/created state is when a process is being created, and the exit state is when a process is terminating and cleaning up.
