Comparison of operating Systems essays Operating systems have evolved from simple standalone and command line programs like MSDOS to distributed multi-user systems like windows and Linux, which support graphical user interface. Every new version of the operating system tries to address the hidden loopholes and to improve the efficiency and security. The file allocation systems and the security implementation are also different between these operating systems. Today's multi user environment has literally stomped out the simple standalone operating system like MSDOS. Windows has also evolved a long way from 16 bit OS to 32-bit operating system. Linux being an open source system is evolving at a faster pace. A comparative study of these three operating systems in context of the important features like user interface, file management, memory management, security implementation would help us discern the similarities and differences between them. MS-DOS was a purely text based operating system before the Dosshell with minimal graphical features was introduced in MS-DOS version 4. Windows is a GUI operating system, which uses a standard display mode for the desktop. Linux by default was a text based (command line) operating system but now users can choose from a variety of graphical user interfaces that are provided now by the X window based graphical display. Two of the common interfaces being the GNOME, KDE. The KDE has a comprehensive office suit, web browser and text editor. The configurability of these interfaces is what differentiates Linux from windows allowing for highly customizable desktop environments. Another key difference between windows and Linux is that the Linux operating system offers graphical user interface abstraction' at the network level as against the hardware level abstraction' offered by windows and other operating systems. [Nathan's Both Linux and windows use the process model. The...
