Description: External scheduling is a resource management strategy that focuses on coordinating and optimizing processes across multiple systems or networks. This approach allows CPU schedulers to efficiently assign tasks and resources, ensuring that workloads are properly distributed among different processing units. External scheduling is characterized by its ability to integrate and manage resources that are not located within a single system, which is particularly relevant in distributed computing or cloud environments. Through this strategy, the goal is to maximize performance and minimize wait times, resulting in a smoother experience for the end user. Additionally, external scheduling can be adapted to various hardware and software architectures, making it a versatile tool for system administrators. In summary, external scheduling is essential for effective resource management in complex environments, allowing for better utilization of available processing capacity and a quicker response to user demands.
