What are the differences between Windows and Linux access control lists?
In Windows, files have an owner (usually the creator), but not a group, to which they 'belong'. - and the owner isn't really important in determining access rights. Files either have an explicit list of people and groups or inherit it from a parent directory. These lists specify individual users and groups (in a list) who have access to the directory/file/subdirectories, and the specific rights granted to each item.
In Unix/Linux, each file and directory belongs to a specific user AND group - for example, configuration files may belong to user root and a group set up for administrators (typically called 'wheel'). Instead of having a list of people who can/cannot access the file, you simply specify read, write and execute privileges for the owner and group the file belongs to, and then anyone else.
In Windows, if you have a configuration file, the owner doesn't matter. Instead you set the ACL to include any Administrators you want to access the file, as well as any other users that may need to read it, including the program it configures.
In Linux, you'd perhaps set the same configuration file to belong to the root user, and the group to which the configured program runs in, and everyone to no rights at all - so only root and the program can read it. Or you could set the owner to the user the program runs under and the group that the Administrators belong to, so the program can read it and so that Administrators et.al. can change the file, but keep everyone set to no rights to keep the configuration secure.
They are two different ways of accomplishing security, each with their own configuration peculiarities and performance issues.
How do you change FAT32 file system to NTFS file system?
1.you can go into my computer under the Removable Disk icon rightclick>format>then under the file system drop-down menu pick the file type (FAT,FAT32,NTFS) and then hit start at the bottom
2.If that don't work, then you might have accidentally deleted the partition, yes they do have them, you can simply stick a windows CD in while the flash drive is connected and reboot, the CD will run. go through its process until you come to the partition menu, the usb drive will be listed as a second drive, but ofcoarse smaller then your computers drive. (*WARNING* this will completely clear all data from the device or your hard drive so make sure you select the right one) Delete the existing partition then select C to create a new one. once your done creating a new partition press F3 and abort the rest, if you don't it will install windows. NOTE under the section saying file type, it will still say RAW when all is done.
reboot and then run threw my above method 1. to format the removable disk and when its complete you will be set as what ever type you choose from the drop-down menu.
This is what worked for me on several occasions however it always results in complete data loss. If anyone knows a better way please post, I would be extremely grateful.
What are typical access rights that may be performed on a directory?
A directory can be created or deleted, can be modified by adding/changing/removing contents, permissions can be changed, as well as primary ownership and primary group membership.
In short, most operations you can do on a file can also be done on a directory. Additional things for a directory are that they can be searched.
What is the target destination for data that has been cut or copied using the office clipboard?
The target destination for data in the clipboard can be just about any Windows application you choose. If this does not answer your question, please think about what you would like to know and ask a more specific question.
What utility do you use to make changes directly to the Registry?
The registry editor, its built into the computer.
turning on the computer, starting the computer, startup, or booting up the computer
What are 4 advantages of Microsoft Excel over Microsoft word?
In Excel you calculate and have alarge number of formulae to perform a variety of operations on the numbers you put into clls. In Word you write text and format written documents.
What are the advantages of using database system instead of file system?
1. Redundency of data means some information may be duplicated in several places in file processing s/y .this can also be refined through DBMS.
2. Accessing of data is difficult in file processing s/y .to access the different data
we requried different program many times in other word for different type application requried different application program .
3. Multiple user can access the same data in DBMS.
4.Security also provided by DBA(Database adminstraror).
The latest trend in operating system is the ability to connect with most devices. These is what is known as compatibility of the operating system.
In ms dos which command can sort files in a directory list?
dir
Lists all files and directories in the directory that you are currently in.
dir /ad
List only the directories in the current directory. If you need to move into one of the directories listed use the CD command.
dir /s
Lists the files in the directory that you are in and all sub directories after that directory, if you are at root "C:\>" and type this command this will list to you every file and directory on the C: drive of the computer.
dir /p
If the directory has a lot of files and you cannot read all the files as they scroll by, you can use this command and it will display all files one page at a time.
dir /w
If you don't need the info on the date / time and other information on the files, you can use this command to list just the files and directories going horizontally, taking as little as space needed.
dir /s /w /p
This would list all the files and directories in the current directory and the sub directories after that, in wide format and one page at a time.
dir /on
List the files in alphabetical order by the names of the files.
dir /o-n
List the files in reverse alphabetical order by the names of the files.
dir \ /s |find "i" |more
A nice command to list all directories on the hard drive, one screen page at a time, and see the number of files in each directory and the amount of space each occupies.
dir > myfile.txt
Takes the output of dir and re-routes it to the file myfile.txt instead of outputting it to the screen.

It is a file extension from apple that plays quicktime movies. They are usually pretty good quality
MOV is a video format that is used in a lot of digital cameras. The most common player is quicktime from Apple computers
MP4 file format (mpeg-4) is short for Moving Picture Expert Group-4ng Picture Expert Group-4. MPEG-4 technology has been developed to provide DVD quality audio and pictures in an extremely small file size and it is quite commonly used in stores like iTunes, iPod and PlayStation Portable (PSP)nowadays. movies and other video encoded in the MP4 file format can result in good quality video, but unfortunately, it generally has to be watched on a computer. Burning the video onto a DVD that will work in your home DVD player will make it much more convenient..
What button from the title bar do you use to make a window fill the screen?

To navigate to the Unit Supply Menu in the SAP Easy Access Screen, you would use the transaction code 'ME51N' for creating purchase requisitions or 'MD01' for planning. However, if you're specifically looking for the overall Unit Supply Menu, you might also use the code 'ISU_MENU'. Be sure to check your organization's specific configuration, as transaction codes can vary.
How is a microprocessors speed measured?
Typically, microprocessors (like the ones found in computers), measure their speed in hertz. A hertz is the measurement of a cycle in a second. So, 10 hertz means 10 cycles per second.
In computing, a cycle (or, more specifically, a clock cycle) is the basic unit of measurement that the CPU uses to carry out instructions given to it by software. Therefore, in a CPU running at 900MHz, 900 million clock cycles will occur per second.
Software sends commands to the processor called, instructions. These commands are the basis for how all programs run on a computer and are handled by the computer in a very complicated manner.
However, a computer running at 3GHz, for example, is not performing 3 billion instructions per second. Some instructions take multiple cycles to complete and some can even have other instructions in the same cycle simultaneously.
To complicate matters further, it is not accurate to say that a higher speed processor is better than another one at a lower speed. Certain AMD processors, for example, run at lower speeds than comparable Intel processors of their family but, because they use different architecture, perform at the same (and, sometimes, higher) performance levels than CPU's with high clock speeds.
Also, processors with some sort of Hyper-Threading technology or, better yet, multiple cores (like Intel Core 2 Duo processors) will be rated at lowered speeds than other CPU's in their price range but, because of more than one (virtual) processor is running parallel to the others, more instructions are performed per clock cycle.
There are also a few more factors to consider but this is the gist of it.
How do you restore the system 32 folder?
UsingWindows XP Recovery Console -
To start Recovery Console from the Windows XP Professional operating system CD
Insert the Windows XP Professional operating system CD into the CD-ROM drive, and restart the computer. When prompted, press a key to start Setup.

At the prompt, enter the password for the local Administrator account to access the contents of the local hard disk. Recovery Console accepts only the local Administrator account password.
From Recovery Console, you can attempt to replace corrupted files with undamaged copies stored on removable disks, such as a floppy disk or the Windows XP Professional operating system CD.
To use the CD-based Recovery Console, you must set the CD-ROM as the primary boot device (the first item listed in the boot order). If the CD-ROM is not listed as a boot-order option in the computer firmware, you cannot start your system by using the Windows XP Professional operating system CD. You must use startup floppy disks to start Windows XP Professional Setup
Using Recovery Console to replace the System file
================================
At the Recovery Console prompt, locate the config folder by typing:
CD system32\config
Create backups of the System or Software files by typing:
copy system <drive:\path\filename>
-or-
copy software <drive:\path\filename>
If they exist, save backups of other files that use file names that start with "system" or "software," such as System.sav or Software.sav.
Replace the current System or Software file by typing:
copy ..\..\repair\system
-or-
copy ..\..\repair\software
Answer the Overwrite system? (Yes/No/All): prompt by pressing Y.
Restart the computer.
And that's solves your problem!¿?!
Firewall define by its name only firewall means the wall of fire. firewall act as a security gateway between two network(usually between trusted and untrusted network) . Basically firewalls depends on the manufacturer. Ike so many are their for example CISCO,JUNIPHER,CHECKPOINT and etc but in the current senario checkpoint firewalls are mostly in use because they are not so costly and also realiable. firewall also have three generations first is packet filter, second is application proxy and third and last is stateful inspection. these are the generation according to checkpoint and stateful inspection firewall invented by checkpoint byself.
