Operating Systems When open source is mentioned, the first thing that typically comes to mind is Linux and other open-source operating systems that have spread like wildfire throughout many organizations.While not entirely open source, Apples OS X operating system is built off of a FreeBSD kernel and relies on open-source components such as Samba. OS X has raised the bar on ease of use for the rest of the open-source operating system group. For Linux and BSD to spread to the user class, desktop environments such as K Desktop Environment and GNU Network Object Model Environment will have to continue to improve their ease of use and feature breadth. But the biggest obstacle facing open-source operating systems is the relative dearth of application support. Windows is still the dominant desktop operating system, and ISVs will have to be encouraged to port their Windows-based software to open-source operating systems. We expect Linux to continue to expand its boundaries all the way from personal digital assistants and cell phones to legacy mainframes and high-performance computing clusters. Henry Baltazar
With the backing of industry powerhouses such as IBM and Oracle Corp., Linux has become a legitimate operating system choice for many enterprises.
