WHY... WINDOWS vs LINUX!!! Comparisons between the Microsoft Windows and Linux computer operating systems are a long-running discussion topic within the personal computer industry. Throughout the entire period of the Windows 9x systems through the introduction of Windows 7, Windows has retained an extremely large retail sales majority among operating systems for personal desktop use, while Linux has sustained its status as the most prominent free software operating system. After their initial clash, both operating systems moved beyond the user base of the personal computer market and share a rivalry on a variety of other devices, with offerings for the server and embedded systems markets, and mobile internet access.
Performance Windows Linux Process NT-based versions of Windows use a CPU scheduler Linux kernel(it is a bridge between applications and Scheduling based on a multilevel feedback queue with 32 the actual data processing done at the hardware priority levels defined. level) once used a scheduling algorithm favouring interactive processes. Memory Windows NT family (including 2000, XP, Vista, Most hard drive installations of Linux utilize aManagement/ Win7) most commonly employs a dynamically "swap partition", a partition dedicated exclusivelyDisk paging allocated page file for memory management. A page for paging operations. This reduces slowdown due to file is allocated on disk, for less frequently accessed disk fragmentation from general use. Linux also objects in memory, leaving more RAM available to allows to adjust aggressiveness of the kernel when actively used objects. This scheme suffers from deciding whether to swap out an application or leave slow-downs due to disk fragmentation it on RAM. Windows does not support such features. Default file The way default Windows file system NTFS(New Default Linux file systems do not require systems Technology File System) works causes files to defragmenting. become fragmented.
STABILITY Windows LinuxGeneral Windows operating systems based on the There are several indirection levels since all applications arestability NT kernel are technically much more stable than some separated from the graphic subsystem which itself is detached from the Linux kernel. As a result of that and because most older versions . Installing unsigned or beta drivers can device drivers are integral part of the Linux kernel, it almost lead to decreased system stability never crashes. The graphic subsystem can only fail if the application is using it in undocumented ways. Even in that case, it can be easily restarted without system reboot.Downtime Reboots are usually required after major system and Reboots are usually required after system and driver driver updates. updates.Recovery In modern, versions of Windows, programs that crash If the GUI hangs, on most distributions, may be forcibly ended through the task manager by CTRL+ALT+F1 (or <CTRL>+<ALT>+ either <F1> pressing CTRL+SHIFT+ESC or CTRL+ALT+DEL to <F6> inclusive) takes the user to the full screen terminal, where the process can be killed, and the GUI restored.
Accessibility and Usability Windows LinuxUser Focus Mostly consistent. Inconsistencies appear primarily through back Interface is usually consistent among the desktop environment ports—software ported from newer operating systems to older used, which follows its interface guidelines. High grade of ones. For example, software ported from Vista to XP must follow customizability is provided in order to adapt to the needs of the the Vista guidelines, those of the newer system (IE7 and Windows user. Some inconsistencies may appear when using programs Media Player11 are examples of this) targeted for different desktop environments.Consistency User interaction with software is usually consistent between Consistency ranges from high to poor between distributions, between versions, releases, and editions, although Windows Vista versions, window managers/desktop environments, and programs. versions generated many complaints about unfamiliar and unexpected Software is generally highly user-customizable, and the user may changes. keep the customizations between versions.Consistency All Microsoft software follows the same guidelines for GUI, Highly consistent.
