Case Study 2 - Question 3


Why do you think the SGI special-purpose systems that DreamWorks formerly used were so much more expensive than the Intel/Linux systems it uses now?

            SGI (Silicon Graphics) is a leading manufacturer of high-performance computing, data management, and visualization products. SGI workstations and servers are optimized for tasks related to computer graphics processing. The company's products target five key market segments: manufacturing, life sciences, energy, government, and media. SGI is based in Mountain View, California, and has offices worldwide.

            SGI recently announced a new technology called Visual Area Networking that allows users to interact with advanced visualization programs from any device over standard networks. Using the company's OpenGL Vizserver 2.0 software, users and groups of users will be able to access programs on supercomputers. This is intended to enable users to visualize and work with data as if their systems had advanced capabilities, no matter what their actual situation.

            Linux is a remarkably complete operating system, including a graphical user interface, an X Window System, TCP/IP, the Emacs editor, and other components usually found in a comprehensive Unix system. Although copyrights are held by various creators of Linux's components, Linux is distributed using the Free Software Foundation's copy left provisions that mean any modified version that is redistributed must in turn be freely available.

            Now, Linux is an alternative for public developed instead Microsoft Windows. It keeps growing in business enterprise by using Linux and Unix is popular among users too.
