Does Linux use round robin scheduling?
Real Time Scheduling Processes
Linux implements FCFS and Yika Robin real time scheduling classes. The scheduler always runs the process with the highest priority. Among processes of equal priority, Linux runs the process that has been waiting the longest.

Which scheduling algorithm is used by OS?
Priority scheduling is a non-preemptive algorithm and one of the most common scheduling algorithms in batch systems. Each process is assigned a priority. Process with highest priority is to be executed first and so on. Processes with same priority are executed on first come first served basis.

Linux nlo a Completely Fair Scheduling (CFS) algorithm, which is an implementation of weighted fair queueing (WFQ). Imagine a single CPU system to start with: CFS time-slices the CPU among running threads. There is a fixed time interval during which each thread in the system must run at least once.
