What is the difference between serial and parallel mode in the context of processes running on a system?
What is the difference between serial and parallel mode in the context of processes running on a system?
In serial mode, processes execute one after the other, while in parallel mode, multiple processes can execute simultaneously.
What is process synchronization and why is it crucial in operating systems?
What is process synchronization and why is it crucial in operating systems?
Process synchronization is the coordination of multiple processes in an operating system to ensure they execute properly without interfering with each other. It is crucial to prevent issues such as race conditions and ensure smooth operation of concurrent processes.
Why is it important to appropriately synchronize cooperative processes running on laptops, PCs, and mobiles?
Why is it important to appropriately synchronize cooperative processes running on laptops, PCs, and mobiles?

Study Notes
Process Execution Modes
- In serial mode, processes run one after another, completing one process before starting the next.
- In parallel mode, multiple processes run simultaneously, sharing the CPU's processing time.
Process Synchronization
- Process synchronization is the coordination of multiple processes to access shared resources without conflicts.
- It is crucial in operating systems to prevent data corruption, deadlocks, and other undesirable outcomes.
- Appropriate synchronization is essential in cooperative processes running on laptops, PCs, and mobiles to ensure efficient and error-free execution.
Uni-Processor System
- A uni-processor system is a system with a single central processing unit (CPU).
- In a uni-processor system, processes execute one at a time, with the CPU switching between processes rapidly.
Sleep Function
- The sleep() function is used to pause a process for a specified amount of time.
- When a process executes sleep(), it releases the CPU, allowing other processes to run.
- The sleep() function impacts process execution by introducing a delay, allowing other processes to utilize the CPU.
Process Synchronization Importance
- If processes are not appropriately synchronized, problems may arise, such as data corruption, deadlocks, and starvation.
- In a uni-processor system, if process P1 gets the CPU first and executes sleep(1), it will release the CPU, allowing other processes to run.
- Cooperative processes running on laptops, PCs, and mobiles must be synchronized to ensure efficient and error-free execution.
Process Synchronization Significance
- Process synchronization is significant in the context of an operating system, as it enables multiple processes to share resources safely and efficiently.
- It prevents conflicts between processes, ensuring that the system operates reliably and efficiently.
