Traditionally, the UNIX command interface was the only way to communicate within a UNIX system. Today, that is not true, with the graphical interfaces that are available. However, the true power of what you can do within UNIX is still in the command line interface.
The command line interface is not very intuitive, and uses commands that are abbreviated to the point of not necessarily being understandable. Also, system administration tasks in Unix have typically been harder to accomplish because of the amount of background knowledge necessary even to do simple things.
UNIX was developed early on for programmers by programmers, and little thought was given to the end user; as a result, it had a reputation of being difficult to use until you took the time to understand the (admittedly) arcane command line interface.

What is the name of kernel in Unix Linux and Windows Vista?
As Unix isn't any particular operating system, there is no distinct name for the kernel. Different versions of Unix may have vastly different kernel structures. The Linux kernel is called, well, the Linux kernel. The Vista kernel is a continuation of the "NT kernel" designed for Windows NT 3.1.
Will physics chemistry and engineering be difficult for you if you are good at math but bad at writing 2000 word essays?

What is the lowest value of current that may cause death?
It is difficult to define the value which may cause death. I think it the voltage which is dangerous. Approximately a voltage of 50V is dangerous for heart.
What is the difficulty in using UNIX?
The usual difficulty that people report concerning UNIX is the use of the command line. The command line has a lot of power and the commands may seem somewhat arcane at times. Like anything else, you have to study what the commands do and how to use them to harness the power of UNIX, but once you do that it isn't that difficult to use.
Which unix command is the equivalent of the find and search commands used in other operating systems?
Your question does not indicate what you searching for specifically, so it is difficult to answer the question, especially since there are many commands in Unix that may do finding or searching of things.
Are unix hosting and Linux hosting the same?
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.
What is Unix configuration?
Unix configuration is the process of tailoring a freshly installed version of Unix to your particular environment. Each Unix system may do that differently.
What is portablity in terms of unix?
Unix is inherently portable; this means that a program, script, or process may be moved from Unix system to Unix system with little effort or change (hence - portable).
Why unix is not effected by virus?
Unix systems may be affected by viruses .. see related link.
What are the advantages and disadvantaages of being able to midlfy unix?
The advantage to being able to modify Unix (or Linux, etc.) is that you can customize it to your liking, and in the case of Linux and its variants you can sell the changes. The disadvantage would be support; if you make a change you are responsible for fixing any problems that may develop.
Difficult to perceive by the senses barely noticable?
Something that is difficult to perceive by the senses or barely noticeable is often described as subtle. It may require closer attention or focus to fully grasp or appreciate.
How do you install PHP on Unix?
To install from source, you may have to use ./configure make make install each in case the server is a unix server
How may system calls does unix has?
There is no exact number because Unix systems vary. However, it is safe to say there are a lot of them, from hundreds to thousands..
Explain what UNIX passwords are regarded as being secure?
This is not a true statement; passwords in any operating system may be compromised by using weak or easily guessed passwords.
Do Unix commands work in Linux?
The ones that are listed as part of a standard (such as Posix) will work in all UNIX systems (but not all systems, such as Windows command prompt). A lot of UNIX vendors add commands that only work in their version of UNIX, so they aren't as portable across systems as others.
