Windows is a line of operating systems produced by Microsoft for use on personal computers, including home and business desktops, notebook computers, and media centers.

Windows Vista is a line of operating systems developed by Microsoft for use on personal computers, including home and business desktops, laptops, Tablet PCs, and media center PCs. Windows Vista contains many changes and new features, including an updated graphical user interface and visual style dubbed Windows Aero, improved searching features, new multimedia creation tools such as Windows DVD Maker, and redesigned networking,


Unix is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations.

The UNIX system has been around for a long time, and many people may remember it as it existed in the previous decades. Many IT professionals who encountered UNIX systems in the past found it uncompromising. While its power was impressive, its command-line interface required technical competence, its syntax was not intuitive, and its interface was unfriendly.


The costs of operating systems are difficult to predict since it changes rapidly if a new version of operating system is launched. The cost of UNIX operating system is difficult to predict because it is developed by many commercial vendors and cost of windows is changing time to time.

However the cost of latest windows operating systems is given below,

Microsoft windows vista ultimate( $207 to $259

Microsoft windows xp sp2( $97 to $239

The UNIX operating system is an open source and it has GNU license and hence its available free of cost or low cost. Now UNIX based operating system LINUX is popular since it’s available free of cost and it supports GUI. Though the operating system available free, maintenance and the added features costs. Linux may be available free of cost, but we must still shell out to get the scalability and support we need.


The Microsoft client/server architecture requires that the user interact with a Microsoft operating system running Microsoft applications on the latest Intel powered PC. The machine, the client operating system and those client applications then interact with other Microsoft applications running on other Microsoft operating systems installed on PC "servers."

The UNIX business architecture, in contrast, relies on smart displays to provide desktop access to centralized UNIX servers. These, like the NCD shown above, typically offer large screens, high resolution, fast graphics and extreme reliability. They have no moving parts and no user-accessible operating system.

UNIX has been used to develop powerful parallel supercomputers. The clusters as well as the newest kernels should be comparable to Windows on multiprocessor systems. However UNIX systems are generally slower than Windows, the best way to compare UNIX systems and Windows performance would be on a cost per unit of work basis. The licensing costs are typically one-time costs that are acquired at the same time the hardware is purchased. It makes sense to combine the hardware and the software costs for performance purposes

The most-fundamental differences between the two architectures have nothing to do with direct cost, but rather user behavior and the relationship between users and the systems group. The chairman mentioned Linux, but everyone needs to remember that Linux is Unix; the Linux kernel and the GNU utilities shared by Linux and Unix help implement Unix's standard set of ideas about user control and how computing should be done....
