Asleep in memory: Process is sleeping but resides in main memory.Ready to run in memory: Further, after processing in main memory process is rescheduled to the Kernel.i.e.The process is not executing but is ready to run as soon as the kernel schedules it.Kernel-running: Process is allocated to kernel and hence, is in kernel mode.User-running: Process is in user-running.Asleep in memory- Process is in memory(not swapped to secondary storage) but is in blocked state.Sleep, swapped- Process has been swapped to secondary storage and is at a blocked state.

Ready to run, swapped– Process is ready to run but no empty main memory is present.

Ready to run in memory- It indicated that process has reached a state where it is ready to run in memory and is waiting for kernel to schedule it.

Preempted- When process runs from kernel to user mode, it is said to be preempted.Zombie- Process does not exist/ is terminated.Kernel Running-Indicates process is a kernel process running in kernel mode.User running-Process is running in user mode which means it is a user process.Created-Process is newly created by system call, is not ready to run.

The states that a Process enters in working from start till end are known as Process states. Kernel processes: They are operated in kernel mode.User processes: They are operated in user mode.Difference between NP hard and NP complete problem.Software Engineering | Prototyping Model.What is Algorithm | Introduction to Algorithms.Software Engineering | Coupling and Cohesion.SDE SHEET - A Complete Guide for SDE Preparation.Difference between LOOK and C-LOOK Disk scheduling algorithms.SCAN (Elevator) Disk Scheduling Algorithms.Program for SSTF disk scheduling algorithm.Free space management in Operating System.Difference between Spooling and Buffering.Difference between dispatcher and scheduler.Measure the time spent in context switch?.Preemptive and Non-Preemptive Scheduling.Process Table and Process Control Block (PCB).Privileged and Non-Privileged Instructions in Operating System.Monolithic Kernel and key differences from Microkernel.Kernel I/O Subsystem in Operating System.States of a Process in Operating Systems.Process states and Transitions in a UNIX Process.ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.
