Why have GRUB and LILO stayed so popular across all major - nix distros distributions?
GRUB and LILO are easy to configure. With them, you can easily boot multiple operating systems from the same menu on the same computer. To triple boot OS/2, Windows 98, and Windows XP, each operating system needs it's own bootloader, and to manage them all, you need to either install a bootloader that can load them all (Smart Boot Manager, Gujin, GAG, etc...), or mess around with boot sectors. With LILO and GRUB, to boot a compatible *nix system, all it takes is editing a simple text file specifying what partition the operating system's kernel is on, and the name of the kernel, or just chainload to a disk or partition to handle the various Windoze flavors, or other proprietary bootloaders.
Short answer - because they work, and in the 'nix world if it ain't broke. . .
But the new kid on the block - Grub 2 - isn't just an incremental upgrade, quite different in several fundamental ways - most of them IMO improvements. Give a recent Debian-based distro (Ubuntu, Mint) a whirl to check it out and get yourself ready for the future!
Can music be played on a Linux computer?
Yes, it can. VLC can play music files locally as well as allow you to listen to web radio stations.
In reference to Linux, PID is Process Identification Number.
3 digit number on the back of credit cards.
In unix systems, a PID is a process ID. It is generally a 15 bit number, and it identifies a process or a thread.

Should operating systems include applications such as Web browsers?
A consumer operating system would probably be quite useless in this day and age without a web browser. A web browser, or at least some method of installing one, should be made readily available to all users. The main complaints about Microsoft doing so were mostly because they made it impossible to uninstall the web browser, and made it too integrated into the rest of the system, increasing security vulnerabilities.
What is the importance of Linux shell?
Linux shell is a programming language. its fully different from others progrmming language.
the script which is used in Linux quite tough to remember if we comparison to other programming laguages.
Linus Torvald's IQ has never been published. If I had to guess, I would estimate it to be around 160.
Why do you prefer Linux operating system instead of windows?
There are a number of reasons why any given person may prefer a Linux OS over Windows, and which ones a Linux user values the most will vary from person to person. But generally they can be summed up as follows:
Relative Security - Because Linux has a much smaller number of users than Windows, it is less likely that criminal hackers will try and write viruses for a Linux system since the number of affected users will be lower. The number of variances in Linux operating systems also means that a Linux virus is less likely to affect all flavors of Linux, which brings us to another reason...
Number of Choices - There are literally hundreds of versions of Linux out there, so even if one doesn't quite suit you, this does not mean all is lost. Sadly, the sheer volume of options can be overwhelming to those accustomed to Windows, and this is one reason why Linux on the desktop hasn't caught on. Having a choice for an OS that is geared toward specific needs makes it a must-have for some (such as Backtrack Linux for security audits).
Customization - This usually applies to the extreme techies. Because the source code of any Linux OS is available, users can modify the code to their liking if they desire. This has led to the development of many newer variants of Linux - where people take existing code from Debian for instance, and then adapt that for another OS (such as Ubuntu) and then another more on top of that (as is the case with Mint).
There is enough modularity in most user friendly operating systems (such as Ubuntu or Mint) to modify them to a large extent even if you cannot code. But the open-source element that would allow a coder to create their own variant is itself yet another reason why people prefer Linux.
Production Approach - Linux is open-source while Windows is proprietary. Linux can be adapted and modified by anyone to their liking, which is appealing to those who are opposed to copyright restrictions on software. Anyone can contribute code to the Linux kernel or to a specific OS for potential inclusion. New releases appear much more often than Windows with most actively developed Linux distros.
Hardware Requirements - The overwhelming majority of all Linux distros require far less computational power to run. There are even some versions of Linux designed specifically for those with old or inexpensive hardware (such as Puppy Linux). This can lead to some performance gains and greater longevity for most computers compared to what you can expect from Windows. Faster boot times and less of a need for disk defragmenting (because Linux uses a different file system approach) are just a few typical benefits.
Overall it really comes down to the user which operating system is better for them. But in general the reasons elaborated above are some of the justifications for why one might prefer to use Linux instead.
Future direction of operating system?
Web Based Operating system with enhancement of artificial intelligence and virtualization
Is Linux a operating system software?
Technically speaking linux is a kernel. The kernel is the part of the operating system that acts as a middleman/translator between the hardware and the software.
What sort of operating system does a Damn Small Linux use?
Designed by Linux, it was originated to run graphic applications on older computer hardware. It was designed by John Andrews.
Where is the Linux operating system used?
Operating systems using Linux are often found on servers, many popular sites' servers run Linux because of its stability and performance. Linux is also used by people wanting to learn how to build a kernel thru example, because Linux is open source, they can. Linux is also used by people who want to build a custom operating system for their needs.
Example open-source operating system?
There are several open-source operating systems, most of which appear to be clones of Unix.
Examples include FreeBSD, Linux, Minix.
How do you install Linux on windows operating system?
If you would like to install it ON TOP of Windows:
Install a virtual machine program (ex. Virtualbox, VMware)
Install Linux inside of virtual machine
Install it along side (or overwrite) Windows:
Reboot computer with Linux install CD/DVD in the disk drive and follow the instructions.
What is the best Linux desktop based operating system?
This is usually a matter of contention. The most popular choices are Ubuntu, Kubuntu, Linux Mint, OpenSUSE, and Fedora.
What is the main character of the Linux Operating system?
Linux is, as you noted, an operating system. It is not a game so it does not have a main character. However, different distributions have different mascots. For example, the mascot for SUSE Linux is a lizard of some sort. The mascot for Linux in general is usually stated to be a penguin named Tux
Different people have different opinions on what distro is best. That's why there are so many. Ubuntu is the most popular distro, due mainly to it's shipping of free CDs, but it is not the only one. Kubuntu, Xubuntu, PCLinuxOS, Mandriva, Freespire, and OpenSUSE are all widely regarded as easy to use / learn. I suggest trying as many distros as you can, to get a feel for the wide variety, and see what you like or don't like in each of them.
As far as hardware support goes, it's pretty much universal across all major distributions. So none is better or worse suited for your hardware. Due to your processor, you will not be able to use any 64-bit distros.
Is Linux a single user operating system?
It is a multitasking, multiuser opearting. It is a version of UNIX .
The majority of Linux distributions are free.
Really? Are you serious? Do you not believe in the almighty Google? Linux is free. (may be hard for you to believe. just Google it) Go now. Get it.
Yes, go forth my son and Windows no more...!
A whole lot of things - as a desktop/laptop operating system, used in embedded system scenarios (smartphones, routers, Raspberry Pi, some media players like older iPods), and as servers.
Should real time operating system be necessarily multiprogrammed?
MULTIPROGRAMING .................. The term multiprograming denotes an operating system that,in addtion to supporting multitasking. In multiprograming more than one jobs are active in memory.Within a very small period more than one jobs are executed simultaneously. MULTITASKING ............... In general multiprogramming implies multitasking,but multitasking does not imply multiprogramming. A multitasking operating system is distinguished by its ability to support concurrent execution of two or more active processes. as discussed actually both multitasking and multiprogramming are same no other answer mentioned are justifiable.....
How a Round Robin scheduling algorithm allocates the CPU to processes?
The round-robin scheduling algorithm allocates CPU time to processes by sequentially assigning the CPU to processes of equal priority that are in the state of being able to use the CPU. (Not blocked) This works by appearing to evenly distribute the CPU amongst CPU ready processes. Processes that are waiting on something, such as an I/O event, particularly waiting on the user to press Enter, are not considered for allocation. Often, there is a priority assigned to the process, which factors in the allocation strategy. Processes that are mostly I/O intensive tend to have higher priority, giving them good response time. Processes that are mostly CPU intensive tend to have lower priority, so they don't interfere with overall system responsiveness.
How do you convert a C program into a Linux kernel module?
Quick Answer: You don't.
Long Answer: It will need a fundamental change before you can have a module that does anything similar. Kernel modules don't have the same purpose as programs. Kernel Modules are meant for device support and similar things. More than likely you don't actually want to move the program to kernel space.
