The 5 "latest" OS's would likely all be various Linux and Unix or BSD based distributions. They update much quicker then windows or mac-os.
As all PCs are microcomputers, Windows, Mac OS X, Linux, BSD, etc. and everything that runs on them.
It's about as easy to use as any Linux distribution. The main point it lacks in is hardware support, which isn't quite as good as Linux's. It uses the KDE desktop, which is also found in many Linux distributions.
No, Linux IS Unix, so the question makes no sense. Unix is a general term for a class of operating systems. Linux is also a term applied to more than one operating system variant, but all Linux OS are Unix OS. Redhat is one type of Linux. BSD is a type of Unix that is not Linux.
There are literally hundreds or thousands of open source operating systems. Some of the more popular one's are Linux based, but there is also BSD or QNX or Haiku. Look at http://distrowatch.com for Linux based open source OS, such as Ubuntu, SuSE, Red Hat, Fedora, etc.
Scribus runs on most modern general-purpose operating systems, including Windows, Linux, Mac OS X, BSD, Solaris, and eComStation.
Mac OS X is based on BSD, which is similar to Linux. Because of this, it is fairly easy to port programs between the two operating systems. However, the two operating systems are not the same, and programs for one don't work on the other. Linux also uses the X window system, and Mac doesn't, though Mac has a program to support programs that use the X window system. Because of this, Linux programs can be configured to run on Mac OS X with a little elbow grease, but not the other way around.
It's a meaningless phrase.
Zorin OS is an operating system like windows 7, vista, etc. and it is part of Linux which is open source meaning that it is free.Windows 7 is not free but can do more than Zorin OS can.
