Solve : What is drivers??

1.	Solve : What is drivers??
Answer» Hi! Me, and probably lots of people, would like to know what drivers are. What do they look like and what do they actually do? Please get back with an example. Let's make it a Windows example for, f.i, a USB port.

I am sorry to say but that link was just techno-jibberich to me. I would like a concrete example. Could you, or perhaps someone else, please provide that? On the other hand, when I create my own OS I will find some other way to interface with the hardware. This is because getting down to it has to do with how the hardware actually work. Best regards, Roger PS The picture in that link was the only useful thing.The link takes you to a Google Search RESULTS Page. Start clicking on some of the results.Hi! I think you have misunderstood me. I got to a Wikipedia page and it was that page that was jibberich to me. But I could have spent a week reading all blue links. And then maybe I would have gotten wiser. I did however find the first article too technological. I have however written some Wikipedia articles myself and I recognize the difficulty in educating "everybody" at plain sight. I often use links myself. Sometimes too many, sometimes too few. But I do almost never write articles like the one about drivers. It was totally noninformant. That is, I wound up with even more questions then I had before reading the article. On the othe hand, this happens when you are ignorant and just want more information. Someone wise told me that the further you go down the rabbit hole, the further you realise how little you know!

anything. It's not like you can find wild device drivers grazing in forests or meadows or something! Quote and what do they actually do? Quote In computing, a device driver or software driver is a computer program that operates or controls a particular type of device that is attached to your computer This "technogibberish" from the wikipedia article seems to answer that question QUITE succinctly. Hi BC! I'm laughing my censored off! I was thinking of some simple commands or something that shows how a driver is written. I do not think I am capable of understanding, I just think these kind of HW interfaces are so basic that I might understand something. But maybe it isn't that simple. Best regards, Roger PS Note that thanks to you, I have learned another new word today, succinctly. Hi! I have come to the conclusion that drivers are unneccesary. If we may select hardware that are available (almost) everywhere and for some considerable time in the future, we may ommit the driver feature totally and just write subroutines for the carefully selected hardware. You will then of course encourage certain HW-manufaturers only. But if you have come to the conclusion that these HW actually are the best, so what? Imagine how much this will simplify an OS. No more desperate search for the optimum drivers for used HW. Just custom made and optimized subroutines for one set of carefully selected HW only. This is the way I will write my OS. Watch and learn :-) Take care! Best regards, Roger Quote from: rogerk8 on November 25, 2012, 02:13:55 PM If we may select hardware that are available (almost) everywhere and for some considerable time in the future, we may ommit the driver feature totally and just write subroutines for the carefully selected hardware. So you are suggesting removing the entire Open architecture of the PC platform and the plethora of hardware manufacturers with various devices built on that platform, in FAVOUR of a single hardware manufacturer. OK, I can follow that. But then you have a problem. You have various competing companies like AMD and NVidia for graphics CARDS. Who makes the decision of which hardware get's to be supported? And, on what planet will the losing company not be fully within their rights to file an anti-trust suit? And what about processors? How do we decide wether Intel or AMD wins? Or, are you even suggesting an entirely new architecture? If so- why would people move to it? There are already plenty of closed-form architectures just as you describe- they only work on a very specific set of hardware. and generally for a very specific task. Quote You will then of course encourage certain HW-manufaturers only. Of course, in the case of a new architecture, you'd be lucky if any HW manufacturer even came on-board. If we are talking about the current PC platform then you still have the problem of what to choose. If you had your way, everybody would be using MDA, text mode adapters and running only pure machine code. Well, that time came and passed, it was called the 80's. Quote But if you have come to the conclusion that these HW actually are the best, so what? Who decides which HW manufacturer is best, and on what grounds? For example, take sound cards. You have on-board sound devices like those provided on many motherboards. So you think "Ah, that's a good one to go with" But then, what about people that want to use their computer as a mixing studio? If their high-end Sound card "isn't supported" because it's not the one sound device that is supported, What do they do? And if somebody wants to actually do something useful with their PC- say, work on a graphics image, or a word processing document- is there any way to change from the 80-column MDA display that the idiot in charge decided was a good idea? No, because it's all written directly in. Quote Imagine how much this will simplify an OS. It won't. Go ahead- look at the Linux sourcecode. It's based on a Monolithic kernel, which is exactly what you just described. What is happening with it? They are basically putting a crapton of drivers right into the kernel, and now they have a hodgepodge method of loading "Kernel Modules". So much for making a simpler OS. Quote No more desperate search for the optimum drivers for used HW. You imply that such searches occur today. They do not. Quote Just custom made and optimized subroutines for one set of carefully selected HW only. And apparently anybody that want's to use their General use PC for purposes not considered by the manufacturer is screwed. Hi BC, my friend! Do you know what the problem with you is? You still seem to think that my version of an OS should be the ONLY one available for people. I am just trying to offer an alternative. And I think I am right. A computer can be made to be much faster and better than today. You just watch me! Thank you for your input by the way. I do appreciate it. It is fun and educational. Take care! Best regards, Roger PS You can always rewrite the subroutines if the exact hardware isn't available. Remember that I love open source... Quote from: rogerk8 on November 25, 2012, 03:18:19 PM Do you know what the problem with you is? You still seem to think that my version of an OS should be the ONLY one available for people. You seem to be speaking generally. "I have come to the conclusion that drivers are unneccesary." You don't say what context. You say it generally. Which indicates a complete lack of understanding of any of the material provided previously, or the very idea and purpose behind drivers. Quote I am just trying to offer an alternative. But, an alternative to who? Who is going to use this currently fictional system? Right now, I only see a market of one- you. And that's fine, but you appear to be under the illusion that this will be something that anybody else is going to want, need, or use. Quote And I think I am right. A computer can be made to be much faster and better than today. You just watch me! You believe computers can be made much faster and better. It's a shame, however, that you have to ask so many questions about how they work to the point where such a conclusion is clearly based more on lack of information and misinformation as well as purposeful confirmation bias than it is based on actual facts. Quote You can always rewrite the subroutines if the exact hardware isn't available. Remember that I love open source... So you are suggesting that people fork the project simply to support different hardware? With only two brands of two pieces of hardware, that's already 4 different builds. Add a third, it's up to 8. add a fourth, we've got 16 builds to choose from; add another? 32. Each new supported piece of hardware requires yet another set of builds specific to all the possible hardware configurations. It is this very problem that Drivers are designed to solve. The OS defines the interface and the hardware manufacturer writes their driver to conform to that interface and "drive" their hardware device.

Hi!

Me, and probably lots of people, would like to know what drivers are.

What do they look like and what do they actually do?

Please get back with an example.

Let's make it a Windows example for, f.i, a USB port.

Bedst regards, Rogerhttps://www.google.com/search?hl=&q=what+is+a+computer+driver&sourceid=navclient-ff&rlz=1B3GGLL_en-GBUS430US394&ie=UTF-8#hl=en&sugexp=les%3B&gs_nf=3&tok=-q1yrmbQSJs0W-y1kRK61Q&pq=what%20is%20a%20computer%20driver&cp=11&gs_id=cb&xhr=t&q=what+is+a+device+driver&pf=p&tbo=d&rlz=1B3GGLL_en-GBUS430US394&sclient=psy-ab&oq=what+is+a+ddriver&gs_l=&pbx=1&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.&fp=7a36a4eb78cfe3bd&bpcl=37643589&biw=1280&bih=633Hi Allan!

I am sorry to say but that link was just techno-jibberich to me.

I would like a concrete example.

Could you, or perhaps someone else, please provide that?

On the other hand, when I create my own OS I will find some other way to interface with the hardware.

This is because getting down to it has to do with how the hardware actually work.

Best regards, Roger
PS
The picture in that link was the only useful thing.The link takes you to a Google Search RESULTS Page. Start clicking on some of the results.Hi!

I think you have misunderstood me.

I got to a Wikipedia page and it was that page that was jibberich to me.

But I could have spent a week reading all blue links. And then maybe I would have gotten wiser.

I did however find the first article too technological.

I have however written some Wikipedia articles myself and I recognize the difficulty in educating "everybody" at plain sight.

I often use links myself. Sometimes too many, sometimes too few.

But I do almost never write articles like the one about drivers.

It was totally noninformant.

That is, I wound up with even more questions then I had before reading the article.

On the othe hand, this happens when you are ignorant and just want more information.

Someone wise told me that the further you go down the rabbit hole, the further you realise how little you know!

Seriously though, they are software, they don't "look like" anything. It's not like you can find wild device drivers grazing in forests or meadows or something!

Quote

and what do they actually do?

Quote

In computing, a device driver or software driver is a computer program that operates or controls a particular type of device that is attached to your computer

This "technogibberish" from the wikipedia article seems to answer that question QUITE succinctly.

Hi BC!

I'm laughing my *censored* off!

I was thinking of some simple commands or something that shows how a driver is written. I do not think I am capable of understanding, I just think these kind of HW interfaces are so basic that I might understand something.

But maybe it isn't that simple.

Best regards, Roger
PS
Note that thanks to you, I have learned another new word today, succinctly.

Hi!

I have come to the conclusion that drivers are unneccesary.

If we may select hardware that are available (almost) everywhere and for some considerable time in the future, we may ommit the driver feature totally and just write subroutines for the carefully selected hardware.

You will then of course encourage certain HW-manufaturers only.

But if you have come to the conclusion that these HW actually are the best, so what?

Imagine how much this will simplify an OS.

No more desperate search for the optimum drivers for used HW.

Just custom made and optimized subroutines for one set of carefully selected HW only.

This is the way I will write my OS.

Watch and learn :-)

Take care!

If we may select hardware that are available (almost) everywhere and for some considerable time in the future, we may ommit the driver feature totally and just write subroutines for the carefully selected hardware.

So you are suggesting removing the entire Open architecture of the PC platform and the plethora of hardware manufacturers with various devices built on that platform, in FAVOUR of a single hardware manufacturer.

OK, I can follow that.

But then you have a problem. You have various competing companies like AMD and NVidia for graphics CARDS.

Who makes the decision of which hardware get's to be supported? And, on what planet will the losing company not be fully within their rights to file an anti-trust suit? And what about processors? How do we decide wether Intel or AMD wins? Or, are you even suggesting an entirely new architecture? If so- why would people move to it? There are already plenty of closed-form architectures just as you describe- they only work on a very specific set of hardware. and generally for a very specific task.

Quote

You will then of course encourage certain HW-manufaturers only.

Of course, in the case of a new architecture, you'd be lucky if any HW manufacturer even came on-board. If we are talking about the current PC platform then you still have the problem of what to choose. If you had your way, everybody would be using MDA, text mode adapters and running only pure machine code. Well, that time came and passed, it was called the 80's.

Quote

But if you have come to the conclusion that these HW actually are the best, so what?

Who decides which HW manufacturer is best, and on what grounds? For example, take sound cards. You have on-board sound devices like those provided on many motherboards. So you think "Ah, that's a good one to go with" But then, what about people that want to use their computer as a mixing studio? If their high-end Sound card "isn't supported" because it's not the one sound device that is supported, What do they do?

And if somebody wants to actually do something useful with their PC- say, work on a graphics image, or a word processing document- is there any way to change from the 80-column MDA display that the idiot in charge decided was a good idea? No, because it's all written directly in.

Quote

Imagine how much this will simplify an OS.

It won't. Go ahead- look at the Linux sourcecode. It's based on a Monolithic kernel, which is exactly what you just described. What is happening with it? They are basically putting a crapton of drivers right into the kernel, and now they have a hodgepodge method of loading "Kernel Modules". So much for making a simpler OS.

Quote

No more desperate search for the optimum drivers for used HW.

You imply that such searches occur today. They do not.

Quote

Just custom made and optimized subroutines for one set of carefully selected HW only.

And apparently anybody that want's to use their General use PC for purposes not considered by the manufacturer is screwed.

Hi BC, my friend!

Do you know what the problem with you is?

You still seem to think that my version of an OS should be the ONLY one available for people.

I am just trying to offer an alternative.

And I think I am right.

A computer can be made to be much faster and better than today.

You just watch me!

Thank you for your input by the way.

I do appreciate it.

It is fun and educational.

Take care!

Best regards, Roger
PS
You can always rewrite the subroutines if the exact hardware isn't available. Remember that I love open source... Quote from: rogerk8 on November 25, 2012, 03:18:19 PM

You seem to be speaking generally. "I have come to the conclusion that drivers are unneccesary." You don't say what context. You say it generally. Which indicates a complete lack of understanding of any of the material provided previously, or the very idea and purpose behind drivers.

Quote

But, an alternative to who? Who is going to use this currently fictional system? Right now, I only see a market of one- you. And that's fine, but you appear to be under the illusion that this will be something that anybody else is going to want, need, or use.

You believe computers can be made much faster and better. It's a shame, however, that you have to ask so many questions about how they work to the point where such a conclusion is clearly based more on lack of information and misinformation as well as purposeful confirmation bias than it is based on actual facts.

Quote

So you are suggesting that people fork the project simply to support different hardware? With only two brands of two pieces of hardware, that's already 4 different builds. Add a third, it's up to 8. add a fourth, we've got 16 builds to choose from; add another? 32. Each new supported piece of hardware requires yet another set of builds specific to all the possible hardware configurations. It is this very problem that Drivers are designed to solve. The OS defines the interface and the hardware manufacturer writes their driver to conform to that interface and "drive" their hardware device.

Solve : What is drivers??
