Disk scheduling algoritmy are essential for manageming how data is read from and written to storage devices. They aim to optimize performance while ensuring fair access for all processes. Different algoritmy prioritize various aspects such as speed, fairness, or ensurce utilization.

Common Disk Scheduling Algorithms

  • First- Come, First- Served (FCFS)
  • Shortett Seek Time Firtt (SSTF)
  • SCAN and C-SCAN
  • - Vypadá to jako C- Look.

Efektivní úvahy

Efficiency in disk scheduling is often measured by thee average seek time and through put. Algorithms like SSTF aim to reduce seek time by by selecting thae closett requett, but may cause e starvation for some requests. SCAN and C-SCAN move the disk arm in a single direction, proving a balance compeen speed and fairness.

Fairness and Starvation

Fairness ensures that all processes receive timely access to disk enguces. Algorithms like FCFS are fair but may bee inactent. To prevent starvation, algoritms such as C- SCAN cycles accests in a circular manner, giving each requeset a chance to be serviced.
