Even in the early days when Linux first came out, it was often commented upon how much faster it was than traditional Unix systems. For many tasks, Linux simply performs better. There are some situations that Linux still has not been optimized for, though, so Unix systems are used to do the "heavy" lifting.
This is not a true or false statement; it all depends on what you are trying to do. Some things execute faster in Linux, and some do not. Overall you cannot say for all things that Linux or Unix are better than one another.
In general, no; both have their strengths and weaknesses. As a general statement neither is more secure than the other.
Because Linux evolved from UNIX, but Windows evolved from DOS.
Linux is considered to be more secure than Windows.
Because Linux is actually more popular in most fields these days than certified Unix.
Unix comes in multiple distributions some more secure than others. Much of the security also comes from how the system is configured. Most unix systems are fairly secure.
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.
No. Linux is a free, open-source version of UNIX. Many of DOS's commands were based on UNIX commands, but the underlying operating system is much more powerful than DOS.
Because Linux was modeled after Unix, and designed to be a suitable free replacement. Windows is targeted at a slightly different market, and was primarily designed to be operated using a GUI, not the command line.

Unix is one of the more secure operating systems, but it would be difficult to give an exact answer. It is very easy (and possible) to make any operating system insecure. It takes individuals some amount of time to secure any operating system, and Unix is no exception to that.
Linux is better than Windows for servers because it is more stable and more secure which are two important reasons why it is better for your server and why you can trust it more.
First off, Macs are computers, whereas Linux/UNIX are operating systems. They are not the same. Comparing OS X, however, is more productive: OS X itself is a UNIX operating system derived from BSD. Objectively, however, OS X falls quite short of the average UNIX implementation or Linux distribution in this category. It allegedly sports the most "user friendly" interface, but this is subjective.
