Almost all Unix systems are proprietary; they are not open source, and you usually only get the binary modules, not the source code.
Unix and MS-DOS are Operating Systems.

Unix is used very similarly to other operating systems (Windows, etc.) for their applications.
Unix, MINIX
Unix-like operating systems are used to save files on a computer operating system. When using this type of system, to unlink a file means to erase or delete it.
Most of the BANKS works on Mainframes which generally uses UNIX operating systems. But a BANK can use UNIX and flavours of LINUX (which is a UNIX flavor) and Windows Server ...

The Net+ exam is vendor neutral, but candidates are expected to know something about the various versions of Windows, Linux/Unix. This exam does not concentrate on Operating Systems, but there are a few questions related to them.
The Unix operating system. The first versions of the Unix operating system were written in the "B" language, and later written in "C", which was invented in order to develop Unix on the PDP-11 machine.
Unix is one of the oldest but still most popular Operating Systems. It was invented in 1969 at AT&T Bell Labs by Ken Thompson and Dennis Ritchie. All the contemporary operating systems of Solaris, HP-UX, Linux, AIX are variants of Unix.
Linux hosting and Unix hosting are not exactly the same thing. Linux hosting and Unix hosting refer to the software operating system employed by the servers of the host. The primary communication being made when a server is described as Unix or Linux is that it is not a Microsoft product. Unix comes in several proprietary versions, Sun Microsystems (now Oracle) and AT&T are two well known commercial versions of Unix. They own and control intellectual property associated with Unix. Linux is a nonproprietary version of Unix. There are many flavors of this. All are "open source." The intellectual property is controlled by one of the various open source models, GPL being the most well know. If a person says they have a Unix server, they may or may not mean the proprietary version of Unix. For many people, unix is a generic reference and can mean Unix or Linux. If a person says they have a Linux server, then it is a Linux operating system. It may be one of over a hundred different types of Linux, but it is based on an open source version of Unix. Note that it is possible to co-mingle the proprietary and nonproprietary versions of Unix, but this is not typically a matter of concern unless you are an expert or unless you are using Apple's version of "open source" Linux. Apple's version works pretty much like open source Linux, mostly, sometimes.
Unix and windows are two separate groups of operating systems. Windows is the operating system of about 90% of personal computers, while unix is the basis of many other operating systems, such as Mac OS X
