Introduction: The Importance of Process Management
In modern operating systems, process management is a core element that determines system stability and efficiency. To provide users with a seamless computing environment, it is crucial to efficiently manage the creation, execution, and termination of processes, and to fairly allocate CPU resources. The efficiency of process management directly impacts the overall performance of the system, which in turn affects the user experience. Therefore, process management is an important consideration in operating system design and development that cannot be overlooked.
Core Concepts and Principles
A process is an instance of a running program, and the operating system manages these processes. Process management can be broadly divided into process state management, CPU scheduling, memory management, and I/O management. Each process goes through the states of new, ready, running, waiting, and terminated, and the operating system must efficiently manage these state transitions.
Process State Transitions
Processes go through various states during execution. The following states generally exist:
- New: The stage where a process is being created
- Ready: The state where a process is ready to be allocated to the CPU
- Running: The state where a process is occupying the CPU and executing
- Waiting: The state where a process is waiting for I/O operations to complete or a specific event to occur
- Terminated: The state where the process execution is complete
The operating system tracks process states and manages state transitions to efficiently utilize system resources.
Latest Trends and Changes
Recent trends in operating system technology are changing with the advancement of AI and cloud computing technologies. Gartner presents AI-native development platforms, AI supercomputing platforms, and confidential computing as top strategic technology trends, and operating systems are also evolving in line with these trends. The Seoul Metropolitan Government is conducting AI utilization training for public officials tailored to actual work environments such as administrative document creation and civil complaint response, and companies are strengthening security technologies such as cloud security, data encryption, and access control.
Practical Application Plans
Process management technology can be used in various fields. For example, web servers use multi-process or multi-thread models to handle multiple client requests simultaneously. Database systems use process synchronization technology to maintain the consistency of transaction processing. In addition, embedded systems apply priority-based scheduling algorithms to ensure real-time performance.

💡 Technical Insight
Precautions When Introducing Technology: When introducing a process management system, it is necessary to accurately analyze the characteristics and requirements of the system and select appropriate scheduling algorithms and resource management strategies. In addition, the latest security technologies should be applied to minimize security vulnerabilities, and continuous monitoring and updates should be performed.
Outlook for the Next 3-5 Years: In the future, AI-based intelligent process management systems are expected to develop further. These systems will be able to predict system load, automatically optimize resources, and proactively respond to security threats. In addition, as the complexity of process management increases due to the spread of container technology and microservices architecture, new technologies are expected to emerge to efficiently manage them.
Conclusion
Operating system process management is essential for ensuring system efficiency and stability. It is important to understand core concepts such as process state transitions, CPU scheduling, and memory management, and to design systems that reflect the latest technology trends. The advancement of AI and cloud technologies will accelerate the innovation of process management technologies, enabling the construction of more efficient and secure computing environments. Process management technology will continue to evolve, and continuous interest and research in this area are needed.
