Study Notes
Scheduling Queues
- Scheduling queues hold processes or devices waiting for processing
- Job queue is the queue where a process is placed when it enters the system
- Device queue is a queue for multiple processes waiting for a particular I/O device, with each device having its own queue
Types of Queues
- Job Queue: holds newly created processes that have entered the system
- Ready Queue: holds processes waiting for execution in the CPU
- Device Queue: holds processes waiting for I/O devices to fulfill their I/O needs
Process Schedulers
- Process scheduling involves removing the running process from the CPU and selecting another process based on a particular strategy
- Schedulers are special system software that handle process scheduling in various ways
- Their main tasks include selecting jobs to be submitted into the system and deciding which process to run
