Operating-System-Algorithms

Implementation of different algorithms used in operating systems.

Different algorithms that include:

1.Job Scheduling Algorithms:

  • First Come Fist Serve
  • Priority
  • Round Robin
  • Shortest Job First (SJF - preemptive)
  • Shortest Remaining Time First (SRTF)

2.Page Replacement Algorithms:

  • First In First Out (FIFO)
  • Least Frequently Used (LFU)
  • Most Frequently Used (MFU)
  • Least Recently Used (LRU)
  • Optimal
  • Second Chance

3.Memory Allocation Algorithms:

  • Best Fit
  • Worst Fit
  • Fist Fit

I implemented these during my 4th semester of undergrad. All of them are in C language. There is also a 'master' file in the 'Memory Allocation Algorithms' and 'Page Replacement Algorithms' directory wherein all the algorithms are combined into one. Have fun learning!
