The PCB is identified by an integer process ID (PID). Once the process finishes its execution, or it is terminated by the operating system, it is moved to the terminated state where it waits to be removed from main memory.Ī Process Control Block is a data structure maintained by the Operating System for every process. Process moves into the waiting state if it needs to wait for a resource, such as waiting for user input, or waiting for a file to become available. Once the process has been assigned to a processor by the OS scheduler, the process state is set to running and the processor executes its instructions. Process may come into this state after Start state or while running it by but interrupted by the scheduler to assign CPU to some other process. Ready processes are waiting to have the processor allocated to them by the operating system so that they can run. The process is waiting to be assigned to a processor. This is the initial state when a process is first started/created. In general, a process can have one of the following five states at a time. These stages may differ in different operating systems, and the names of these states are also not standardized. When a process executes, it passes through different states. A collection of computer programs, libraries and related data are referred to as a software. When we compare a program with a process, we can conclude that a process is a dynamic instance of a computer program.Ī part of a computer program that performs a well-defined task is known as an algorithm. For example, here is a simple program written in C programming language −Ī computer program is a collection of instructions that performs a specific task when executed by a computer. A computer program is usually written by a computer programmer in a programming language. This section contains the global and static variables.Ī program is a piece of code which may be a single line or millions of lines. This includes the current activity represented by the value of Program Counter and the contents of the processor's registers. This is dynamically allocated memory to a process during its run time. The process Stack contains the temporary data such as method/function parameters, return address and local variables. The following image shows a simplified layout of a process inside main memory − S.N. When a program is loaded into the memory and it becomes a process, it can be divided into four sections ─ stack, heap, text and data. To put it in simple terms, we write our computer programs in a text file and when we execute this program, it becomes a process which performs all the tasks mentioned in the program. A process is defined as an entity which represents the basic unit of work to be implemented in the system.

The execution of a process must progress in a sequential fashion. A process is basically a program in execution.
