These operating systems perform basic tasks‚ such as tracking of directories and files on the disk‚ sending output to the screen for display‚ recognizing input from the keyboard and controlling peripheral devices such as drives and printers. The following are the differences in memory management between Linux and Windows (Godbole & Kahate‚ 2011). Windows Windows uses a data structure

Just as these efforts were beginning to show some results‚ however‚ Microsoft faced a new threat to its global market position – open-source software. Open-source operating system software‚ such as Linux‚ gives governments and businesses in developing countries a way to avoid paying any server software licensing fees to Microsoft. In 2000‚ the Brazilian state of Penambuco became the first government entity to pass a law that requires the use of open-source

time processes. Round Robin is also used for time-share‚ meaning that each process is given an equal “time Slice” to be processed by the CPU. Real Time processes have the highest priority and usually over rule any other process at the time. In Linux‚ the two processing scheduling algorithms used for real time processes is Round Robin and First-in-First-out (FIFO). These two scheduling algorithms allow real-time processes to be executed in a timely fashion‚ and a time-sharing algorithm is used
