Introduction to CPU Scheduling Algorithms
Explains the concept of CPU scheduling algorithms and process management in the operating system.
Non-Appropriative Scheduling Policy
Describes algorithms where processes take over the CPU until their assigned time ends, such as FIFO and Shortest Job First (SJF).
Appropriative Scheduling Policy
Contrasts non-appropriative algorithms by allowing the CPU resource to be transferred to different processes based on priorities, including algorithms like Round Robin and Shortest Remaining Time First (SRTF).
Evaluation Parameters for Scheduling Algorithms
