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.
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.
he is a Finnish software engineer best known for initiating the development of the Linux kernel. He now acts as the project's coordinator.
What is an operating system interface?
It is a set of commands or actions that an operating system can perform and a way for a program or person to activate them.
Which programming language is used to develop Linux operating system?
C, C++ and scripts in Bash, Perl and Python
Can a wireless keyboard be used when installing Yellow Dog Linux on the PlayStation 3?
Yes, YDL has access to the usb/bluetooth ports of the PS3 so you shouldnt have any problems
How can you recover the overwritten files in SCO Unix HTFS file system?
Answer
Recovering any 'deleted' and/or 'overwritten' file in a typical Unix system is problematic and much more difficult to do reliably than it is with, say, a typical Windows system. This is a function of the way the files are stored on a Unix system, not a problem with, or feature of, the operating system itself. I suggest you obtain and study Wietse Venema's TCT (The Coroner's Toolkit) for further information. [JMH]
Define NFS in operating system?
NFS is the Network File System, and allows directories from systems to be used in other systems in a sharing arrangement.
What is difference between Linux and window 7 operating system?
linux uses alot less ram than windows 7 (the more ram used the slower the computer). therefore linux makes your computer run faster
Can you replace getch of C programming in Linux without using iostream header?
There is a 'getch' in 'conio.h' which has nothing to do with 'iostream'.
Most Linux distributions can handle most of those tasks just fine. The one major hurdle would be inter-language support. Ubuntu, Debian, Fedora, and OpenSUSE all have excellent translations in a wide variety of languages. They include or make it easy to install all of the multimedia codecs, compilers and IDEs, and have a large selection of educational Linux programs. Ubuntu even has a variant designed especially for education, know as Ubuntu Education Edition (formerly Edubuntu).
Difference between until and while in Linux?
Both loop constructs have the same syntax:
while [test expression]
do
commands
done
until [test expression]
do
commands
done
Where they differ is that the 'while' loop only executes where the test expression evaluates as True, whereas the 'until' loop executes where the expression evaluates as False.
Functionally, you could achieve the same result using either loop construct by altering the test expression. Eg.:
while [n -gt 5] #n is greater than 5
is functionally identical to
until [n -le 5] #n is less than or equal to 5
What is X windows environment?
ambot sad nimo uie Mao na ako assignment... tan awa imong lobot naa'y answer... j3j3j3j3j3
A broad question, with equally broad answers. Computers are useful in many ways, from organizing complex data sets, storing large amounts of data (including WikiAnswer), interpreting said data (such as finding charts, plotting out data, trending and detrending data) displays of virtual worlds, communicating and associating with others, dealing with complex physics or engineering simulations... Really, the limit to the computer is more the data storage capacity and the speed of processing. Everything else is up to the user and programmer.
An operating system is the software that runs your machine such as windows / linux / mac. So if you were to upgrade it you are simply upgrading to a newer version
What happens if you press ALT and F4?
In Windows or Linux closes the active window opened. If no one window are open the system asks to shutdown the computer.
Yes. It is included in the repositories of Ubuntu and Debian.
Can you run programs compiled with Turbo C on Linux?
Turbo C cannot compile native Linux binaries, only programs for MS-DOS. MS-DOS applications can be run on Linux through a variety of methods, including DOSEMU, DOSBox, QEMU, Bochs, and VirtualBox.
What is multitasking Linux operating syatem?
Any Linux-based operating system that is capable of multitasking. (I.E. doing more than one thing at the same time.)
What is the difference between multitasking multiprogramming and multithreading?
Multiprogramming is a rudimentary form of parallel processing in which several programs are run at the same time on a uniprocessor.Since there is only one processor, there can be no true simultaneous execution of different programs. Instead, the operating system executes part of one program, then part of another, and so on. To the user it appears that all programs are executing at the same time. Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time. The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the program running in the computer
What Linux command sets a files permission?
In Linux the chmod command is used to set file permissions.
What is a web based operating system?
A web-based OS is a system where all the applications and data his held on the internet. The operating system is essentially like any other operating system except that it runs out of a browser.
