The document discusses the various states a process undergoes in operating systems, defining a process as an active program that includes multiple components such as the program counter and stack. It outlines the key states: new, ready, ready suspended, running, blocked, blocked suspended, and terminated, explaining each state's role in the process life cycle. The content includes a reference link for further information on process states.

Topic : Different States and Process in
Operating Systems
 A process is an active program. It can also be said as a program that is under
execution. It is more than the program code as it includes the program
counter, process stack, registers, program code etc.
 A process passes through different states as it executes. These states may be
different in different operating systems.

4. z  New  This is the state when the process has just been created. It is the
initial state in the process life cycle.
 Ready  In the ready state, the process is waiting to be assigned the
processor by the short term scheduler, so it can run.
 Ready Suspended  The processes in ready suspended state are in
secondary memory.
 Running  The process is said to be in running state when the process
instructions are being executed by the processor.
 Blocked  The process is in blocked state if it is waiting for some event to
occur.
 Blocked Suspended  This is similar to ready suspended. The processes in
blocked suspended state are in secondary memory.
 Terminated  The process is terminated once it finishes its execution.
