It can be. The kernel has a real time process scheduler, and there's a popular real time patchset that is often used to modify the kernel to be a more dedicated real-time system.
There are basically four types of operating systems. They include Batch Operating System, Multiprogramming Operating System, Network Operating System and Distributed Operating System.
Palm OS is generally not considered a real-time operating system. True real-time operating systems are multi-tasking; the "real-time" refers to the ability to effectively manage resources to achieve a result in as little time as possible. Palm OS is single-tasking, so the speed at which it performs is mostly bottlenecked by the individual application running. Windows CE is a real-time operating system; most uses of it are in multi-tasking devices. Linux is not necessarily a real-time operating system, but can be configured that way, depending on the scheduler selected.

long-term scheduler...
The four major parts are: the kernel, process manager, file manager and scheduler
The dispatcher in Operating System is a module that selects the process from the ready queue for allotting it the CPU (Processor). There is a switch associated during dispatching and that is the process status changes from ready to running. The dispatcher is placed in between the ready queue and Processor Scheduler (i.e. short term scheduler).Rajiv

Disk Scheduling and Task Scheduler and different terms. Disk Scheduling: Input / Output Scheduling or I/O Scheduling is a term used to describe the method computer operating systems decide the order that block I/O. Task Scheduler: Task Scheduler is a component of Microsoft Windows that provides the ability to schedule the launch of programs or scripts at pre-defined times or after specified time intervals. It was first introduced in the Windows 95 Plus! pack as System Agent [1] but was renamed to Task Scheduler in Windows 98. The Windows Event Log service must be running before the Task Scheduler starts up.
A scheduler is used to manage and coordinate tasks or jobs within a system, ensuring that they are executed in a timely and efficient manner. It helps optimize resource utilization, prioritize tasks based on criteria such as deadlines or dependencies, and maintain system performance by avoiding bottlenecks or conflicts. Schedulers are commonly used in operating systems, databases, batch processing systems, and job scheduling applications.
No. The Job Scheduler is the high-level scheduler.
The long-term scheduler, also known as the job scheduler, is responsible for selecting processes from the job pool and loading them into memory for execution, determining the degree of multiprogramming. In contrast, the short-term scheduler, or CPU scheduler, selects which of the ready processes in memory should be executed by the CPU next, making decisions on a much shorter timescale, typically in milliseconds. While the long-term scheduler controls the overall balance of the system, the short-term scheduler focuses on optimizing CPU utilization and responsiveness.
What is job scheduler and dispatcher?
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.
