Jobs or processes are the same.
Whereas, Job scheduler and CPU scheduler are two different terms.
Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler.
While Job scheduler selects the processes from the job pool (Job pool is on the Hard disk) and load them in to the memory (Main Memory or RAM) for execution. in other hand CPU scheduler selects among the processes (in RAM) that are ready for execution and allocates the CPU to one of them.
Hope I got it right and answered your query. Sorry for any mistakes as I'm not perfect as well. :)

preemption means to stop a running process temporarily and start a new process according to different scheduling criteria. after completion of new job, the older one can be restarted.........
in fcfs scheduling there is a shortcoming that is if any rocess of maximum brust time is first ome. and after that many short burst time process come. then smaller pocesses have to wait for a long time untill the max brust time process complete their execution. in case of shortest job first it applied the method to give shortest t\burst time job to processer first.

The characteristics include: 1. job or process management 2. management of I/O devices and resources 3. scheduling job batch 4. memory handling/allocation/management 5. file handling/management 6. error reporting 7. resource protection
dynamic job shop scheduling is the scheduling of the machine it can processes different jobs at time. it switches from one job to another job. in real time process jobs are executed based on the time.
1. Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler.2. Job scheduler selects the processes from the job pool and load them in to the memory for execution. in other hand CPU scheduler selects among the processes that are in ready to execute and allocate the CPU to one of them.3. CPU scheduler is faster than the process scheduler.Read more: What_is_the_difference_between_the_job_scheduler_the_CPU_scheduler
In flow shop scheduling, jobs are processed on machines in a set order. Example would be a shirt that must be cut from fabric first then put onto a sewing machine. All shirts go through this process. In a job shop environment, these precedence depend on each job. Each item has their own order to be processed on machines and may take a different path than other jobs.
There are many providers of job scheduling software. Halcyon Software make the Advanced Job Scheduler that one can downloaded from their official website.
Information about job shop scheduling can be found at ShopTech, Realtrac, Global Shop Solutions, OptiSol, Roll-Kraft, and Velocity Scheduling Systems.
Process plant controlling, process optimising, process trouble shooting, process scheduling and above all over all idea regarding plant instrumentation and controls ( which reduce trouble shooting job)
Key challenges in job shop scheduling problems include managing multiple job priorities, limited resources, and minimizing production time and costs. These challenges can be effectively addressed by implementing advanced scheduling algorithms, optimizing resource utilization, and using real-time monitoring and adjustments to adapt to changing conditions. Additionally, implementing efficient communication and coordination among different departments can help streamline the scheduling process and improve overall productivity.
The systems compatible with Enterprise Job Scheduling is dependent on who manufactures the software. Check with an IT professional for advice specific to your workplace.

In that work system, the shortest job gets higher priority because more gets accomplished in any amount of time. If you have two hours to do 4 tasks and one task will take five minutes, one will take 30 minutes, one will take an hour and one will take an hour and a half, by using the shortest job first method, you will accomplish three tasks in those two hours and part of the fourth task. If you do the longest job first, you will accomplish the task that takes an hour and a half, then only part of the one hour task, but nothing on the 5 minute or 30 minute tasks. That means that by doing the shortest jobs first, you will accomplish three times as many tasks as you will by doing the longest jobs first.
