Which one is more powerful Windows or Linux hosting?
Both Windows and Linux hosting is powerful. If you use ASP or .NET then you should use Windows hosting platform. If you do not, then you can use the more affordable and more popular Linux hosting platform.
How does mozila Firefox differ from Linux?
Mozilla Firefox is a web browser and is not really related to Linux in most regards other than it is prepackaged and may be included in their repositories. However, in certain special cases they may rename it altogether to avoid copyright issues (e.g. Iceweasel in Debian).
Is the ls command in Linux equivalent to ls -FC?
The 'ls' command is the same in Linux and Unix systems. System Administrators may set up an alias that has the -FC or other options but the command itself with no other parameters (ls) is just the 'ls' command.
What is the difference between Linux and Windows file systems?
Windows uses 4 file systems: FAT, NTFS, exFAT, and ReFS.
"Linux" supports dozens of file systems, there are too many to mention. The differences between them are massive and specific to the file system in question.
For a proper answer you need to read http://en.wikipedia.org/wiki/File_system .
It is incorrect to say "the Linux file system is faster than Windows" because it's dependent on the data, and of course because there is no "Linux file system." It's incorrect to say "The Linux filesystem is more/less secure than the Windows file system" for the same reason. Drive encryption is available in both Windows and Linux.
To the average user, there is no functional difference.
Why do you think Unix and Linux share more commands than Windows XP and Unix?
Because Linux was modeled after Unix, and designed to be a suitable free replacement. Windows is targeted at a slightly different market, and was primarily designed to be operated using a GUI, not the command line.
The .ko extension is placed on kernel modules (loadable drivers) in Linux.
Further, '.ko' extension is called 'kernel Object', and is implemented from kernel 2.6 onwards, this is perhaps the biggest change as far as loadable kernel modules are concerend.
For example, the serial device driver that in Linux 2.4 lived in the file 'serial.o' in Linux 2.6 lives in the file 'serial.ko' .
How do you simulate a command as root?
If by simulate you mean to run command as root i.e with root privileges then sudo is the command.
sudo <command name>
which execute the command with root privileges.
Generally yes. Most Linux versions will work on a standard home PC, and many will work on one too old and slow to run Windows.
What Windows Vista command is the equivalent of the Linux ifconfig command?
From a command line: ipconfig or, for more info: ipconfig /all
From Windows itself, the control panel provides access to networking features and configuration.
In a workspace, there are program windows.
Consider whole GUI of MS Windows to be a single workspace.
What utilities could you use to force the NIC on your Linux server to use full-duplex transmission?
Linux use this popular utility called ethtool to allow users to view and change NIC settings
What are device files used for in Linux?
Device files are useful for performing raw data operations. For instance, redirecting plaintext document to a printer (echo text.txt > lp0) instead of launching a dedicated program or interface for the task.
How do you install drivers in Linux?
Most drivers are developed and included in the kernel; if your hardware isn't supported by the kernel, it likely isn't supported by any other drivers. The only real exceptions are for some graphics cards, like those from NVIDIA and ATi, as well as some experimental drivers for wireless cards that aren't included in the kernel for various reasons. Some wireless cards can be made to work by wrapping a Windows driver for use in Linux when no other alternative exists.
NVIDIA and ATi drivers are installed by running an installer downloaded from the respective websites. In Ubuntu, they can also be installed by using the Restricted Drivers Manager. ndiswrapper can be downloaded from most distro's repositories, as well as compiling from source.
How many lines of code are in the Linux operating system?
There is no real answer to that, because there is no theLinux operating system. There are several different operating systems that use the Linux kernel but incorporate a variety of different software, each varying in size and code complexity. The Linux kernel includes approximately 13.5 million lines of code, although much of this code will not be used in any given binary kernel image, as it is platform or usage-specific.
Portmap is a server that converts RPC program numbers into DARPA protocol port numbers. It must be running in order to make RPC calls.
The port mapper (rpc.portmap or just portmap, or rpcbind) is an Open Network Computing Remote Procedure Call (ONC RPC) service that runs on network nodes that provide other ONC RPC services.
The port mapper service always uses TCP or UDP port 111; a fixed port is required for it, as a client would not be able to get the port number for the port mapper service from the port mapper itself.
The port mapper must be started before any other RPC servers are started.
The port mapper service first appeared in SunOS 2.0.
What are the advantegis and disadvanhtages of the Linux?
Freedom is the advantage. it is free as in speech and mostly free as in beer. You can use it with
- The freedom to run the program, for any purpose (freedom 0).
- The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
- The freedom to redistribute copies so you can help your neighbor (freedom 2).
- The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.
Disadvantages? I do not find many. It is not perfect and there can be trouble with drivers - but Windows has just as many driver problems. Maybe the biggest problem is that it can be hard to find professional support. On the other hand there is a lot of free online help so it is not a major difficulty.
How does Linus Torvalds the author of Linux pronounce his first name with a short i or a long i?
i believe that in finnish it is pronounced with an 'ee' type sound, but he pronounces it with a short i sound.
What partition holds the kernel and other data the system needs when Linux boots?
it isn't the same for every single set up, sometimes it doesn't even have it's own partition. if you're just looking for the files themselves, see /boot
How you add the group students to your Linux or Solaris system?
You can create a new group with the command groupadd.
Ex. 'groupadd students'
What does Yellow Dog Linux do?
Yellow Dog Linux is a Linux distribution targeted at computers with PowerPC and Cell processors (such as older Macs and the PlayStation 3).
Why do people use Linux. Its illegal?
Linux is not illegal. Linux is a free, public license software modeled on Unix.
Why doesn't Linux store file creation time?
Most Unix-like operating systems don't store the creation time (crtime). If you think about it, its actually not a very useful feature to most people. If the file has never been changed, then its creation date would be the same as the last modified time (mtime) anyway. If the file was automatically created by a program or when the system was installed, the times for several files might be the same, making it useless for organization. If you import files from a file system that doesn't store creation time or had the wrong system time, the time will also be wrong or useless.
A few file systems for Linux (such as ext4, for instance), do have the technical capability to store crtime, but very few tools and libraries have been updated to make use of it, as it is 1.) not standard or common, and 2.) is not really useful and thus not a very high priority.
