Mac OS X
Mac OS X – Beneath the appealing, easy-to-use interface, you’ll find an industrial-strength, UNIX-based foundation, called Darwin, that is built from the ground up for superior stability and performance. Darwin evolved from a joint effort by Apple engineers and programmers in the Open Source software community. Together, they’ve created a robust, modern operating system foundation to help your Mac run faster and more reliably than ever.
Darwin features a protected memory architecture that allocates a unique space for each application. When
applications are isolated in their own memory space, you don’t need to restart your computer if something goes wrong. Darwin simply shuts down the offending
application, letting you continue working or playing
Windows XP – The new Windows with a new look is built on an enhanced Windows 2000 engine and is supposed to give users the freedom to create, connect and communicate in new ways. Microsoft hopes that Windows XP will establish a new standard in power,
reliability, security and simplicity. The operating system will be available on October 25, 2001, in two editions: Windows XP Home Edition and Windows XP Professional Edition for businesses of all sizes.
Steve Ballmer, Microsoft’s chief executive officer, says that “Windows XP will be the highest-quality Microsoft operating system ever,” and that users will encounter “new computing experiences.”
The issue of quality has been heavily stressed by Microsoft, as it has positioned the product to be much more stable and fault-tolerant than previous versions.
