These questions include the mechanics of implementing multiple processes on machines with one (or a small number of) cpu, synchronizing them, and using them to solve common coordination problems within operating systems.
Unit 3 Presentation Pdf Process Computing Concurrency Computer Basic concepts of concurrency: a concurrent program specifies two or more sequential programs (a sequential program specifies sequential execution of a list of statements) that may be executed concurrently as parallel processes. Download: chapter 3 process concurrency.pdf. this open education resource is a collection of collection of concepts of operating systems in question & answer form that are useful as out of class activity while flipping the classroom. Process relocation refers to the ability of an operating system to move a running process from one memory location to another or even migrate it between machines . So, to protect against concurrency bugs, we must assume that the scheduler can interrupt us at any time and schedule any other process. in other words, assume that the scheduler is adversarial, and will do the worst possible scheduling. to prevent weird and rare concurrency bugs, your code must work correctly even when faced with an evil scheduler.

A concurrent program: it is a program that has multiple threads or tasks of control allowing it perform multiple computations in parallel and to control multiple external activities that occur at the same time. The result of execution is as if all operations were executed in some sequential order, and the operations of each processor occurred in the order specified by the program. Hardware based concurrency control mechanisms rely on special atomic cpu instructions (compare and swap and test set lock), that perform indivisible atomic operations.
