Job scheduling is the process of planning and organizing tasks or jobs to be executed by a computer system or workforce. It ensures that resources are allocated efficiently, allowing multiple tasks to run smoothly without conflicts. This is crucial in environments like operating systems, where various applications need to share CPU time, or in manufacturing, where different machines must operate in a coordinated manner. Effective job scheduling can improve productivity and reduce downtime. It involves setting priorities, determining the order of tasks, and managing deadlines. Tools and algorithms, such as round-robin or first-come, first-served, are often used to optimize the scheduling process, ensuring that all jobs are completed in a timely manner.
