Hello world OS from scratch, a template for absolute beginners

CSC405: Operating System [OS] & CSL404: Operating System Lab [OS Lab] <Semester IV>

Open source operating system, with an unique design that explores new possibilities like Webassembly runtime, Kernel mode containers, memory safety and more.

An Operating Environment made in Python with some tools and Linux like interface.

Here is the code for various Operating System Algorithms.

For the Katos-Katos

Created programs to simulate two different scheduling algorithms i.e. First come, first served and Preemptive Round Robin scheduling

A very simple operating system, based on MikeOS. Check MikeOS here http://mikeos.sourceforge.net/

A basic operating system kernel, by me. This will be updated everyday if I have time. This kernel is based on https://github.com/iknowbrain/NIDOS.

Context Switching involves storing the context or state of a process so that it can be reloaded when required and execution can be resumed from the same point as earlier. Act of switching from one process to another is called a "Context Switch".Typically there are several tasks to perform in a computer system. So if one task requires some I/O operation, you want to initiate the I/O operation and go on to the next task. You will come back to it later. When you return back to a process, you should resume where you left off. For all practical purposes, this process should never know there was a switch, and it should look like this was the only process in the system.

The Scheduling problem is solved by Round Robin algorithm.

Operating System Project is a collection of modules that together implement a modern-day operating system. Each module performs a basic operating system service such as device scheduling, cpu scheduling, interrupt handling, file management, memory management, process management, resource management, and interprocess communication.

An online project to learn the working of an operating system.

Android Application executing CPU Scheduling Algorithms like FCFS, SJF, SRTF, LJF, LRTF, Priority (Preemptive and Non-Preemptive), and Round Robin.

Project eXpOS (eXperimental Operating System) is an OS built from scratch.

[In progress] Open-source operating system, just for fun and it may be intended for commercial use later, although the main purpose is for all of us to learn a lot and to enjoy the process.

This is the WIKI for the LanternOS project. The WIKI is in the form of a website hosted at https://enygmator.github.io/LanternOS.WIKI

A basic unix shell built in C language.

The Preemptive Round Robin Scheduling Algorithm is an important scheduling algorithm used in both process scheduling and network scheduling. Processes are executed for a predefined unit of time called a quantum. Once the CPU executes the process for the specified time slice, the process either terminates or returns to the back of the ready queue if the process has any remaining burst time left. Numerous proposals have been made to improve the static quantum time of the Round Robin Scheduling Algorithm; most research focuses on the optimization of the ready queue. In this paper, I proposed having predefined optimized quantum times for most process that can be retrieved whenever a new process enters the ready queue.
