Hello everybody!
As you know the computer from the software aspect of view consists of some applications,scripts,data....compiled and configured but as i expect there is not enough integrity which i think causes a promotion of the whole computer.
some examples : my webcam is detected in Mandriva2011 as an unknown device,at the same time only "vlc media player" and "kopete" can use that device!!..? even an application named "Enable Viacam" can not use it.This is the error:
Can not initialize the camera.
Perhaps is being used by other application
My question is that how i can manage and obtain a higher integrity level in my PC?
Please help and thank you in advance

Because English is not your first language, there are some words here that do not make sense---eg What do you mean by "promotion of the whole computer".

I also don't know what you mean by "integrity" in this context----I would think that SW integrity would be about reliability, consistency, etc.

It seems that your real question is how to get your webcam working---if so, I'd start by finding out the make and model and doing some web searches.

Here is my webcam as found by "dmesg|grep video":

Hello
You are right about the English not being my first language besides to that i have never been in an English speaking country.
"Promotion" as i understand and meant is :raising the level or rank or value of something.
"integrity" as i think means all in one and i tried to make it more clear by giving an example as: "my web cam" and although i like to solve webcam problem in my PC,but comparing with the main subject(integrity) the webcam problem is too small.
There are many other examples about disintegration in computers!
I think the computer must be as a unit entity as usually all users expect that.But now and at the present time it is not because it consists of different software which are not interrelated enough,because many software act independently and sometimes in the opposite direction

You can get the maximum integrity only in closed systems. For example, embedded systems are maximal integrated. This is because all the hardware and all the intended functions are known at design time, so that you can choose one set of applications/software that supports the hardware and is delivering the intended functions.
On general purpose systems, like the "average" PC, neither the hardware not the intended function is known at design time, every user has different functions for his system and uses different hardware combinations. So you can't choose the one toolset that fits all, you have to offer a broader approach. This is how distributions like Slackware, Fedora, Debian, Ubuntu, ... work, they are general purpose distros that deliver you different tools for any purpose to choose from. This causes implicit a not very tight integration, because it is possible to replace one tool with a different one, just as the user wishes.

If you want a tighter integration than maybe one of the special purpose distros is worth a look, assuming that you have a special purpose for your system, like Backtrack for security and network experts, SystemRescueCD for recovery purposes, antiX for old computers or even Android for embedded devices.

If that doesn't work out for you you can also try to build your own special purpose system, for example beginning with a Debian minimal system and building up on that, tailoring it exactly for your needs.

Hello and thank you TobiSGD but at present time what i need is just some(maybe new) commands or some core utilities or complementary applications or scripts which can be used in getting a higher level of integrity in computer.
I am also thinking to some possible internal links which might be helpful in this case.

To get higher integrity you have to build a system from the ground up or switch to a system that is specific for your purpose. There is no command/software that gets you automatically a higher integrated system.

cough! I think he means "integration", being a "device works with all apps", ala, "Plug n Play".

This is tough (difficult to control) on a system that is capable of running software from different gui styles (kde, gnome, lxde, xface, etc, etc.).

We tend to, mistakenly sometimes, use a particular webcam app for chat like kopete, and a different system is used by an other app like skype.

Both work, but not well together.

Sometimes with so much choice and freedom, it misleads us.

I hope this helps.

software in a computer very much resemble the individuals in a community each having preferences and goals which sometimes are different,but in more organized and harmonized societies for example in political parties generally all individuals want the same thing and act in the same way they also try to help and enhance each other,they are also more interrelated comparing with others!
Another example is schizophrenic patients who have different personalities compared with normal or mentally stronger people who act better and are more successful,so this is not a plug and play but integration around the axis of root which causes more strength and makes it possible to use all available possibilities and even data! this way no problem if i am using kde or genome both of them and all other applications must do their best to help me.
developers and software makers and code creators try a lot to create some applications to do something useful but if we can raise the level of integrity we will get much better and more valuable results because : there are already a lot of information and data in any computer which are not used enough just because of low level of integration and harmony created and caused by an stronger master mind software in the core of any operating system.
As i said before "my webcam" was just an example to show that a device is regarded as unknown by one application(harddrake) and at the same time is successfully used by another application(vlc media player) both in the same computer!! i want to make it possible to use or share the data and information existing in one software with some other software(like those in the center of any operating system) to raise the level of integration in a computer.one question is how to make it possible for harddrake to use the existing information in kopete or "vlc media player"to be able to know and configure "webcam".
As you know Linux software are mostly open source so could be changed or mixed with each other then there would be no legal inhibitory factors preventing the intermixing of software..
Thank you for spending your time
