Process Synchronisation | Critical Section Problem | OS | Lec-54 | Bhanu Priya
Education 4u・2 minutes read
Process synchronization in operating systems involves independent and cooperative processes, with synchronization issues arising only in cooperative processes due to shared resources. The critical section problem, solved by ensuring mutual access to shared variables, includes code segments like entry, critical, exit, and remainder sections.
Insights
- **Independent processes** in operating systems do not impact the execution of other processes, while **cooperative processes** can affect each other due to shared resources, leading to synchronization issues.
- The **critical section problem** in process synchronization involves ensuring that a code segment with shared variables is accessed by one process at a time, requiring the implementation of entry and exit sections to manage mutual access effectively.
