how RAM works


i just want to know the proper working of RAM.

1. What is the technology used in it?

2. If user wants to see movie then how does it keeps the data from hard disk and show us

3. Is there any specific amount of space given to program when it runs if so who decides it?

4. If we copy something from one drive to another then does it use RAM ?


i just want to know the proper working of RAM and know who instructs it to do the work.


thanx in advance.

I asked your question in Google: how RAM works. Survey the results.

Oh, come on, this is homework surely?

There are many technologies used in RAM, from technologies used in the packaging, to technologies used in the preparation of silicon wafers, to lithographic technologies and circuit design technologies so while when your instructor asked you this question, when it will have had a context, there may have been a sensible answer, without that context there are thousands of answers.

Wow, what a shift of question type. I have no idea how you can have got from the type of question that question one appears to be to this, which seems to ask for a 'programs run, they do stuff' type of answer.

Quote:
3. Is there any specific amount of space given to program when it runs if so who decides it?
I think its Richard Stallman, although he claims that it isn't

Quote:
4. If we copy something from one drive to another then does it use RAM ?
Oh, alright, here is an answer: Yes. Although, you could contrive a situation in which the RAM was not used for the data being transferred from one drive to the other, doing that without using RAM would be difficult (and it would work badly).

I note that this question doesn't ask '....does Linux....' or '....does Windows...' but purports to be more general. Having said that you could contrive a situation in which the disk data itself did not use RAM, the fact that the OS does use RAM means that the clear answer, for the situation in which you use an OS, to the different question 'Can you transfer data from one hard drive to another without any ram in your computer?' is no, for cases in which you use a conventional OS to do the transfer, because you will need ram to run the OS.

That is, as noted, still not the same as saying 'there is no way to transfer data from one i/o device to another without using RAM to buffer the data'.

althjough, oddly, you haven't asked about that

the use of 'who' here is something of a puzzle. 'Which program...?' or 'How does the CPU...?' or something would have made more obvious sense, but you could be getting at the notion that the user calls one program, which calls another, which calls another....which gets data into and out of ram (and so its the user of the computer, eventually) or you could be thinking of the CPU or you could be thinking of the memory controller, I just can't guess.

You have not followed-up in your last thread. This supports the notion that you are just throwing homework questions at us.

What reading have you done on computer memory technology?

I hate when people ask their homework on here... it makes me want to say antidisestablishmentarianism fifty times in a row.... just to see if it could magically make people actually do the research that the assignment is intending for them to do... but then I remember I am actually a weak agnostic atheist and don't believe in anything happening magically... still... laziness isn't always a bad thing, but laziness that leads to asking other people to do your work, is.

I am saying this, since I think it's quite clearly established... this is somebody asking us to do his homework for him, that and the fact the questions actually have nothing specifically to do with linux what-so-ever...

Ok, how much ram does it take to render tux? lol

Don't hack on everybody asking for help with their homework on here. I am guilty of it, except this person did not even attempt to know anything before asking those questions.

I will give him/her something that will make them think.

RAM is a waiting room, so-to-speak. As you access info from a HD it goes through a few processes, one of them being RAM. As the processor uses the data for execution it pulls it from the RAM. Why? Because it does not have to search for it, it is all lined up just waiting to be used. BTW - you cannot do anything on a computer without RAM, a keyboard, a monitor, a motherboard, a processor, or a storage device, or electricity.

Have a good day. Oh, and if you want to learn about computer science you will have to open a lot of books.

Blessings,
Shaun

first of all this is not a homework question.
and i was reading about "millipede technology" all i read was how it works but didn't understand where it is used in system and as i hav read about hard disk and hopefully this technology is not used in hard disk ,so i asked the question of "RAM technology" . Don't think that i'm asking stupid questions its all to clear my doubts , only my way of asking question was wrong .

Hope u understand and please reply for it .

RAM

Random Access Memory works with the processor and the swap file to give a result but there is no lasting image, or at least thats how I visualise it.

OK--we'll accept that, BUT:

You really need to respond to people's questions. Mine was:

What reading have you done on memory technology? For example, have you seen the terms "dynamic RAM" or "flash memory"

And you still have not followed up in your last thread, where I was also trying to help you.

That doesn't excuse the asking of a 'HW' question. If YOU want to learn something then some effort on your part must be made to gain the understanding in order get knowledge. To formulate a question to a forum and not your instructor with the intent of using the forum's replies doesn't do you any good nor society to support such actions.

So to excuse it because you did it just attempts to excuse your actions (guilty mind). It's just wrong, like cheating on a test.

If the OP had presented some information with a request as to clarify same then others could/should aid. But the OP does have the responsibility of including reference notes as to the source of supporting material.

i followed u r last thread please see it
and for this question of yours "MEMORY TECHNOLOGY"

i have read about "Millipede TECHNOLOGY" in this how entire chip is approached and how cantilevers work ,how does it read data and write data ..about its speed how fast it reads and writes data. But i didn't find anywhere written where this technology is used..

If u want to see this then go to "IBM" site u'll find it ..

SO my question is where this technology is used in computer because this techonolgy is not used in hard disk..

WTF?

i dont think so.
Quote:

of course, evreything does.
at minimal you need one byte to store the data.

this is a homework question, and the operating system.

@kaushal*;

You will need to help us connect all this. First, you asked "what is RAM", and now you are talking about "millipede technology". Are they related?

Have you looked up "RAM" or "random-access memory" on Google or Wikpedia?

Did you notice that some of the articles on "millipede technology" are quite old?
