We are not sure what you mean by "shearing", it is men that "shear" sheep in timed competitions, not operating systems.

Is unix a realtime operating system?
Some versions of Unix are oriented towards real time applications, and processes in Unix can be "promoted" to real time status if desired. Other than that, you would have to define more precisely what you mean by real time for an operating system.
What does POSIX real time Thread specification define?
"Portable Operating System Inferance (for Unix)
What makes Unix a multi-user operating system?
Unix is considered a multi-user operating system because multiple users may use the server/system at the same time. Each user has their own address and process space and they don't interfere with each other.
What is the example of time sharing system?
One example of a time-sharing system is the bank's bankcard system, which allows hundreds of people to access the same program on the mainframe at the same time. The Multics & Unix operating systems are time sharing Operating Systems
Why is Unix unsuitable as a real time operating system?
I don't know that one could say it is "unsuitable". There are some versions of Unix that are optimized for real time activity, but in general Unix was designed as a multi-user operating system that did not have the constraints you would find in a real-time environment. It is optimized for many users, but not necessarily for real-time event handling. Depending on the situation that the real-time calls for it might be more efficient to use an operating system or environment that was designed just for that purpose, rather than using a general multi-user system. In Unix, setting up a real-time program would mean degrading the performance of other users, since the real-time program would need priority. Although you could do it, it really isn't in the nature of Unix to behave well this way.
How secure is Unix?
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.
Who makes Unix?
Unix (officially trademarked as UNIX, sometimes also written as Unix with small caps) is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations. As of 2007, the owner of the trademark is The Open Group, an industry standards consortium. Only systems fully compliant with and certified to the Single UNIX Specification are qualified to use the trademark; others are called "Unix system-like" or "Unix-like". During the late 1970s and early 1980s, the influence of Unix in academic circles led to large-scale adoption of Unix (particularly of the BSD variant, originating from the University of California, Berkeley) by commercial startups, the most notable of which are Solaris, HP-UX, and AIX. Today, in addition to certified Unix systems, Unix-like operating systems such as Linux and BSD are commonly encountered. Sometimes, "traditional Unix" may be used to describe a Unix or an operating system that has the characteristics of either Version 7 Unix or UNIX System V. Contents
What is an Unix server?
Unix (officially trademarked as UNIX®, sometimes also written as Unix or Unix® with small caps) is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs including Ken Thompson, Dennis Ritchie and Douglas McIlroy.It is important because counting all of the various flavors of UNIX (freeBSD, openBSD, Solaris, HP-UX,etc. also sort of Mac OS-X) and all of the Linux Flavors (which are sort of descendants of UNIX systems) would make up a large portion of all of the computers in operation.Unix is important in and of itself because it was designed to handle multiple stations connecting to a central hub which, in turn, may itself be connected to other hubs. This defines a network with a star topology which, amazingly enough, is the same as the basic structure of the entire internet.In a nut shell UNIX is an operating system which at one point in time, was the most prevalent operating system in use. It is still widely used in scientific and professional circles. 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. Unix is a family of multi-user operating systems. It was originally developed by AT&T in the 1970s. Unix has a very strong security and model and relatively simple design, making it popular and fairly easy to implement. Many operating systems are either based on or modeled after the first Unix systems, such as Linux, Solaris, or Mac OS X.
What are the disadvantages of having two users on your computer?
They cannot use the same computer in the same time, only if it runs a multiuser operating system (unix).
For bank system which opertating system is best?
As we have to go with high security and no wastage of time at employees work place it is better and best to opt UNIX or its flavors as the operating system
What operating system is designed to deal with input output and processing requests from many users?
Unix was designed specifically to handle many users and requests at the same time (time-sharing).
Why unix is the best operating system than other operating system?
There is no way to answer this question in sufficient detail. "Unix" is a term for a variety of operating systems, many of which have only a few features in common. And with a variety of operating systems on the market, there may or may not be differences between them and "Unix" in selected areas.
