Study Notes

Operating Systems: Process Management

Process management is one of the essential functionalities of an operating system. It involves creating processes, managing these processes, and ensuring that they do not interfere with each other. This section will explore the basics of process management using examples from various operating systems to illustrate key concepts.

Process Creation

Each process has its own unique identity known as a process identifier (PID) which helps distinguish it from others running on the same machine. PIDs can range from zero upwards, depending on how many processes exist within the system. When a program is launched, an operating system creates a new process by allocating memory resources and setting up communication channels between the process and any input/output devices used by the program.

Process Synchronization

In multi-threaded environments, there is a need for synchronization to prevent race conditions and ensure proper execution of processes. For example, in the Solaris operating system, a mechanism called mutexes (short for mutual exclusion) is used to control access to a limited resource, such as a database or file. When a process needs to access the resource, it acquires a lock associated with that resource, preventing others from accessing it simultaneously. Once the process finishes its task, it releases the lock so other processes can proceed.

Process Communication

Process communication involves passing information between different parts of an operating system or between applications running within the same machine. One way this can occur is through interprocess communication (IPC). IPC allows processes running in separate operating systems to exchange data using various mechanisms such as shared memory, message queues, or remote procedure calls. For instance, if two interconnected processes need to communicate using TCP/IP sockets, they would typically establish a connection via the socket interface and then send messages back and forth.

Process Termination

When a program completes execution, the corresponding process also comes to an end. The process's resources are returned to the operating system, which may include any allocated memory, files opened during the process' lifetime, and other resources such as network connections or input devices. If a process experiences issues and needs to be terminated manually, it can be done either by sending a signal using the 'kill' command or by issuing the 'abort' command while logged into the process' terminal.

In conclusion, process management plays a vital role in operating systems, enabling efficient execution of multiple tasks simultaneously while maintaining orderly progression and preventing conflicts. By understanding process creation, synchronization, communication, and termination mechanisms, we gain insight into how modern computer systems handle concurrent workloads effectively.
