Scheduling algoritmus, hogy az adott eszköz a kezelői rendszer, a vezérlés, a vezérlés, a végrehajtásihatékonyság, a Shortt- Job First (SJF), a Rund-, a Robd, a Robd, a RCFS, a Shortest Job Firset (RJF), a Robs- és a Robs-, a Robs- és a Robs-, a Robs- és a Robs-, a Robs- és a CPU-k.

First- Come, First- Servede (FCFS)

Az FCFS ütemterv szerint a rendszer a következő esetekben lép fel:

Example: Processes with burst times 5, 3, and 8 arrive sequentially. The Gantt chart show s execution order and calculations for waiting and d turnaround time.

Számítások:

  • Process 1: Waiting Time = 0, Turnaround Time = 5
  • Process 2: Waiting Time = 5, Turnaround Time = 8
  • Process 3: Waiting Time = 8, Turnaround Time = 16

Shortett Job First (SJF)

SJF selects the process with the smallest burst time next. It minimizes averizes waiting time but requires know of process durations forehanded.

Usingste same processes, SJF menetrend them a 3, 5, then 8 units, leading to o different waiting time.

Számítások:

  • Process 2: Waiting Time = 0, Turnaround Time = 3
  • Process 1: Waiting Time = 3, Turnaround Time = 8
  • Process 3: Waiting Time = 8, Turnaround Time = 16

Round Robin Scheduling

Round Robin assigns each process a fixed time slike or quantum. Processes are cyclede hyugh until completion, promoting fairness and responvenes.

A projekt célja, hogy a projekt a következő területeken valósuljon meg:

Example calculations for proces completion times and d waiting times are a következő:

  • Process 1: Waiting Time = 4, Turnaround Time = 9
  • Process 2: Waiting Time = 2, Turnaround Time = 5
  • Process 3: Waiting Time = 8, Turnaround Time = 16
