Find the actual contents of the Process Control Block (Process Descriptor) in the operating system of your choice. I know in general PCB contains. Process number or process ID. Process state. Program counter. CPU registers. CPU scheduling information. The main job of all operating systems is to run and coordinate user tasks. Like many operating systems, the basic unit of work in FreeRTOS is the task. FreeRTOS uses a Task Control Block (TCB) to represent each task.

When a task is actually executing it is said to be in the Running state. It is currently utilising the processor. If the processor on which the RTOS is running only has a single core then there can only be one task in the Running state at any given time. Ready.A task control block is implemented to provide more efficient user task access to task-specific variables and context information.
