You already got your answer the last time you asked the very same question.

We don't know about Linux here, either. But we do Windows...

Write two programs that simulate two versions of a paging memory management system - one based on FIFO algorithm, another one based on LRU. Make the following assumptions:
the size of the internal memory is 40K, and it is divided into 10 page frames;
the system loads and runs one process; the length of the process is 80K (thus, it is to be divided into 20 pages).
Your driver program will be a loop running 40 times. On each run of the loop, it randomly generates a reference to a page in the process (a number in the range from 0 to 19) and makes sure that the referenced page gets a page frame. The driver will count and print out the total number of page faults; every time when a page fault occurs, it will print out the number of the page that caused the fault and the number of the page frame it gets.
Run the driver program first time using the FIFO memory management system and save the reference string generated by the driver. Then run (a slightly different) driver program, using the LRU. Compare the numbers of page faults occurred in both cases.

And? What's the question?

hello!
can anybody guide me how to change windows-xp administrator or guest password from its registry
|
|
|
|

You cannot get the password but you can reset the password. You'll need a boot CD with some tools on it to do this, like ERD Commander, or some other tool, possibly even UNIX-based, to do it.

thanks.
could you please tell me in some detail how to do all that using bootable cd.
|
|
|
|
|
You'll have to read the docs for the app CD you get.

Hi,
my problem is the following - I have some files that my application is using.
these files are valueable and I want to protect them from being copy by the user.
the state is this:
the application is installed only in my company on some computers.
the users are not administrators.
I can't put the files in the server because they are being used locally by the application and they are very big, around 800MB.
I need somehow to prevent copy/burn/whatever for the user but allow a read permission for my application.
how can I do it?
thanks.

There's no way to do that. Since the application runs in the security context of the suer that launched it, it needs Read permission to, obviously, read the data file. Read permission is the only one a user needs to copy a file to another location. There's no way to prevent it.

that is what i thought and was afraid of...
but maybe there's some third party solution - somekind of lock folder utility that cab accessd through command line (with parameters) that my application will be able to unlock but user won't be able to.
thanks anyhow.

That won't work either, because all the user then has to do is launch your application (or run the utility to unlock it), switch back to the Desktop and copy the file.

how would he do that? he won't have the password.

What password?? You can't protect a single file or folder with a password. NTFS doesn't support it.

Security is based on user accounts, not applications. If you remove the read priv from the file, no app you run can read it, including the one app that needs to read it.

Like stated in the previous posts, there is no way to prevent the user from making a copy of the file if the app runs with the user's context. You could, however, encrypt the data-file. Depending on the encryption technique, there is a possibility of your application working significantly slower than before.
Additionally, the decryption routine AND the decryption key kave to be somewhere in your application (which is stored on the users computer). Thus, it is possible (though maybe not feasible) for the user to obtain these (by disassembly).
I believe what you NEED is a good licence agreement (ask a lawyer). This will not enable you to entirely prevent spread within one company, but will give you additional legal leverage if you discover that your data files have been sold to others (e.g. competitors).
Cheers,
Sebastian

If this is an intranet only app, make it client server with the full dataset only stored serverside.

first of all - thank you all for replying me.
let me be more specific -
I know that the regular OS capabilities do not let me do that, what i'm looking for is some thiord party solution like "Cryptainer PE" or "Lock Folder XP" that will give me a command line option to access the encrypted files but won't really put them out to a shared/visible folder.
BTW, the 'place files on server' solution is obvious but not suited for me as I have a lot of files and each is very big.
BTW2, my application is working in my company and the users are my employees. It's not for a commercial use but for private use by the company.
I hope things are a bit more clear now.

OK, I got the solution - http://www.everstrike.com/shield.htm[^]
it gives the option to hide the files and also i can define a list of applications that can have an exception and will be able to see it.
