Round Robin (RR)(CPU Scheduling)

  •  Used in time sharing systems.
  • Similar to FCFS with time Quantum.
  • It is Pre-emptive.



Advantages

  •  Easy to simple to implement.
  • Each process gets a fare share of CPU.
  • No Starvation.
  • No Convey Effect.
  • Deterministic response time.
  • Priority is same for each process.

Disadvantages

  • Throughput depends on time quantum.
  • if Time quantum is small then more overload of context switching average waiting time in created.
  • if  Time quantum is large then same as First come First Serve.
  • Decide size of Time Quantum is very tough.

Operating System

What is an operating system? An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all of the other application programs in a computer. The application programs make use of the operating system by making requests for services through a defined application program interface ( API ). In addition, users can interact directly with the operating system through a user interface, such as a command-line interface (CLI) or a graphical UI (GUI). Why use an operating system? An operating system brings powerful benefits to computer software and software development. Without an operating system, every application would need to include its own UI, as well as the comprehensive code needed to handle all low-level functionality of the underlying computer, such as disk storage, network interfaces and so on. Considering the vast array of underlying hardware available, this would vastly bloat the size of every application and make software ...
