What exactly are you asking? Different algorithms are used for different things. Are you asking about

1) Scheduling - tasks/threads
2) Memory Allocation
3) Disk Allocation
4) Task swapping

Round robin is typically scheduling
FIFO/LIFO/best fit/first fit are typically allocation
FIFO/LIFO can be scheduling or task swapping
