Successful resource management improves system performance, reduces response times, and prevents resource bottlenecks.

Resource management is one of the basic functions of the operating system and is particularly important in multi-user or multi-tasking systems. The operating system allocates the resources required by each process, monitors their usage, and releases them when they are completed. This process uses prioritization algorithms and scheduling strategies to ensure optimal use of resources.

Resource Management Strategies

• Time-Sharing: It shares CPU time among multiple processes, allowing each process to run for a certain amount of time.
• Prioritization: It ensures that more important processes have priority access to resources by assigning priority values to processes.
• Memory Management: It allocates and frees memory areas needed by applications, using memory efficiently.
• Virtual Memory: It allows larger applications to run by using disk space as memory when physical memory is insufficient.
• Input/Output Management (I/O Management): It optimizes data transfer by streamlining input/output operations and prevents conflicts between devices.
• Resource Allocation Algorithms: When distributing resources, it takes into consideration factors such as justice, efficiency and priority and makes the most appropriate decisions.
