Where can one find Linux jobs?
One may find Linux jobs through a variety of sources, most of which are online. One may call the company directly at its headquarters to inquire about job opportunities currently available, or visit the company's website to inquire. Other websites that cater to those searching for Linux jobs include Indeed, Monster, and Linkedin.
When you create a device special file in what folder should it be stored in Linux?
Usually they are stored in /dev
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' .
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.
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.
In a workspace, there are program windows.
Consider whole GUI of MS Windows to be a single workspace.
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.
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.
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 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.
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 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.
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).
Is Linux less expensive than other operating systems such as Windows?
Linux is free. However, this question can be taken at an angle of total cost of ownership or time cost investment. Since specific versions or distributions are not specified this cannot be answered. Some RedHat versions can be more expensive than some Windows versions. Linux sometimes takes more time to maintain than Windows, so overall it can switch license costs into time costs. If Windows systems take fewer employees to run, then the higher initial license costs can be viewed as necessary and Windows as "less expensive" over time.
For a private party on a personal computer, Linux like Ubuntu, can be less expensive to install and operate.
Is there a list of Linux error codes?
Either type linux error codes in a web browser and have a look through the websites on the subject, or go into the file system. Follow this path: /user/include/asm-generic/errno.h and you will find a list of error codes there.
Why do people use Linux. Its illegal?
Linux is not illegal. Linux is a free, public license software modeled on Unix.
