Partitioned Allocation Memory Management

Main memory is divided into separate memory regions or memory partitions. Each holds a separate jobs address space.

• Static Partition - Job sizes will enter the partition
• Dynamic Partition - Job sizes will enter the CPU to create a partition
  • Best Fit

* A process is said to be running if it currently has the CPU
* A process is said to be ready if it could use the CPU if one were available
* A process is said to be blocked if it is waiting for some event to happen before it can proceed

• Non-preemptive - Process CAN'T be taken away by another process
  • First Come First Serve
  • Shortest Job First
  • Priority
• Preemptive - Process CAN be taken away by another process
