Let’s start with the basic concepts of scheduling. Scheduling is a fundamental operating-system function. Almost all computer resources are scheduled before use. The CPU is, of course, one of the primary computer resources. Thus, its scheduling is central to the operating-system design.
Round robin algorithm is one of the CPU scheduling algorithms used to schedule processes in the CPU in a way that the time taken to complete all processes is less. In this algorithm, every process is given a fixed amount of time to complete its task and later again given CPU if the duration is not completed. Meanwhile, other processes are provided CPU for the same fixed amount of time in a cyclic way. This process uses the concept of context switching so that states of preemptive processes are saved.
- First Come First Serve Scheduling
Strength:
- Easy to understand and implement.
- Starvation of processes is not there.
Weakness:
- Wait time is very high.
- Processes at the end have to wait for so long to get their chance to acquire CPU.
- Shortest Job next Scheduling
Strength:
- Beneficial for the processes with less burst time.
- Short-time processes can be executed in a faster way.
- Hence this increases the throughput.
Weakness:
- Every time CPU has to check for the process available with the shortest time.
- Processes with larger burst time have to wait
- Starvation of processes is there
- Processes at the end have to wait for so long to get their chance to acquire CPU.
