Process Synchronization - aryanjoshi0823/5143-Operating-System GitHub Wiki
In an operating system, process synchronization refers to the coordination of multiple processes to ensure that they execute correctly when sharing resources or data. Proper synchronization avoids conflicts and ensures the consistency and correctness of shared data.
What is Process Synchronization?
Process synchronization is a technique used to manage the access of multiple processes to shared resources (e.g., memory, files, or data structures). Without synchronization, processes may encounter issues such as:
- Race conditions: When multiple processes access shared resources simultaneously, the final outcome depends on the order of execution.
- Data inconsistency: Improper access to shared data can corrupt it.
Need for Synchronization
- To ensure consistency of shared data.
- To prevent race conditions during concurrent execution.
- To allow cooperation between processes in a multitasking environment.
- To ensure that processes execute in a specific sequence when required.
