Operating Systems Lecture Notes. UNIX is one of the most widely used operating systems in industry, government and education. For this reason, all air conditioners use the same cycle of compression, condensation, expansion, and evaporation in a closed circuit. Please note that the textbook does not cover all the materials we teach in the lectures. Multiprogramming in Operating System. This version is a modification of a set prepared by Prof. A water supply system is analogous to the human circulatory system.

Inter process communication IPC is used for exchanging data between multiple threads in one or more processes or programs. The Processes may be running on single or multiple computers connected by a network. The full form of IPC is Inter-process communication. It is a set of programming interface which allow a programmer to coordinate activities among various program processes which can run concurrently in an operating system. This allows a specific program to handle many user requests at the same time.
Principles of Coordination
Everything you need to know about the principles of coordination formulated by Mary Parker Follett. Principles refer to fundamental truths on which an action is based. In order to ensure effective co-ordination, the co-ordination should be based on certain principles. Effective co-ordination entirely depends upon effective leadership. Co-ordination and leadership together can assure direction of corporate efforts effectively towards the predetermined objectives.
For hospitals and health care institutions, ensuring that patients receive proper care takes more than performing procedures and making diagnoses. Communication is a crucial component in all steps of the health care process. Whether it be a clinic accurately sharing patient information with another facility, or a group of doctors, nurses, specialists, and other staff at a hospital discussing how to treat current and incoming patients, the need for concise, effective communication is always present in the health field. Health care professionals and institutions need to recognize the importance of communication in health care in order to thrive. This shows that better communication methods would benefit both patients and health care providers. Effective communication — both intrahospital and interhospital — is important for health care providers to protect their patients, save on costs, and increase day-to-day operating efficiency. Meanwhile, patients benefit from increased access to their medical histories, which reduces chances of medical errors.
Inter-thread communication or Co-operation is all about allowing synchronized threads to communicate with each other. Cooperation Inter-thread communication is a mechanism in which a thread is paused running in its critical section and another thread is allowed to enter or lock in the same critical section to be executed. It is implemented by following methods of Object class :. Causes current thread to release the lock and wait until either another thread invokes the notify method or the notifyAll method for this object, or a specified amount of time has elapsed. The current thread must own this object's monitor, so it must be called from the synchronized method only otherwise it will throw exception.

An independent process is not affected by the execution of other processes while a co-operating process can be affected by other executing processes.
Inter-thread communication in Java
Some of the techniques that are used to achieve effective coordination are given below:. Direct Contact : One of the most effective means of achieving coordination is direct contact. Written communication, modern electronic, mechanical devices, etc.
In computer science , inter-process communication or interprocess communication IPC refers specifically to the mechanisms an operating system provides to allow the processes to manage shared data. Typically, applications can use IPC, categorized as clients and servers , where the client requests data and the server responds to client requests. IPC is very important to the design process for microkernels and nanokernels , which reduce the number of functionalities provided by the kernel. Those functionalities are then obtained by communicating with servers via IPC, leading to a large increase in communication when compared to a regular monolithic kernel. IPC interfaces generally encompass variable analytic framework structures.
