Linux

Because they have applications that won't run on it.

Yes Linux does support the creation of multiple user accounts.

If you wish to learn to use the command line, these commands are how you create a new account along with a password.

1) useradd "new account name"

2) passwd "name of new account"

you will be prompted for a password then asked to retype it.

to delete a user type:

userdel "name of account"

to delete the account and all the accounts files type:

userdel -r "name of account"

All of the commands I've listed must be run by the root account.

It's warm. It's fuzzy. It's controlled by a diabolical dictator named Tux who gives free cookies to the cookie monster.

Secure Shell (SSH) uses TCP port 22, so that is the port that you would need to forward.

Linux can be adapted to a wide variety of environments, some even contradictory. For instance, you wouldn't want the same distro that runs a 64-core server on your PDA. You wouldn't want FlightLinux controlling your desktop. Some distros are designed to run well on very old or cheap hardware. Others are designed to showcase the latest accelerated desktops and gaming. Some are designed to be used only as LiveCDs, while others are designed to be installed using a traditional text-mode installer. Some are optimized for multimedia production or media centers (Ubuntu Studio, 64Studio, Mythbuntu).

There are also philosophical differences between the different distros. Some will offer or bundle proprietary (or closed-source) software (Xandros, Freespire), while others find the idea repulsive (Fedora, gNewSense, Debian.) Some believe that programs hsould be built from source and specifically tailored for each machine (Gentoo), while others believe that pre-built software should be offered as a matter of convenience (pretty much everybody else). Some are created by or sponsored by competing commercial backers (OpenSUSE, Ubuntu, Fedora, Xandros), while others are created by non-profit groups or individuals (Debian, Puppy Linux, Gentoo).

Most Linux distributions have a software repository that you can access like an App Store, most of which are Free/Open Source Software (F/OSS) but there are notable exceptions such as Ubuntu Software Center that also provide commercial software. The software in a repository tends to be designed to work with that particular distribution and that particular version, so is always the first place to go for new software

There are hundreds of different types of networks used for different purposes and using any number of protocols. Without knowing what it is you plan to achieve by "networking two computers together", it is impossible to guide you through a particular course of action. For instance, did you want to set up an NFS share, a Samba/Windows SMB share, an FTP server, an HTML server, a Jabber server, an IRC server, a game server, a PXE boot server, or some other type of client/server setup?

It's neither. Linux is its own family of operating systems. It is modeled after Unix and shares many design goals, but it is not completely inter-operable. Also, to be legally called a "version of Unix", an operating system must go through a rigorous and expensive certification test, which no Linux distro has currently done.

No. Linux is not an *anything* Unix.

The physical address is the memory block where things are stored during use. Linux uses physical to virtual and virtual to physical to access the Linux kernel and user work space. For more information you can check these web sites: Andries Brouwer's Linux Kernel Notes: http://www.win.tue.nl/~aeb/linux/lk/lk.html (see section 9) There is also a physical address for network cards. That address is input at the factory when the network card is manufactured. There is an online forum about How to Enter Physical Address in Wireless Network, which you can find here: http://ubuntuforums.org/showthread.php?t=494842

The exact meaning of this question is unclear. Most Linux systems may be shutdown in a variety of ways from the local console or a remote shell login via SSH or telnet for example.

If logged in as root at a command line interface (CLI), the following commands will likely change the runlevel of most Linux systems.

For a system halt, type "init 0", for a system reboot, type "init 6", for a system halt, you may also type "halt", for a system reboot, you may also type "reboot", to exit multi-user mode and enter single user mode, type "init 1" and to return to multi-user mode, try typing "init 3" and so on...

Invoking the "init" command allows you to change the runlevel 'on the fly' without first executing a full shutdown of the system. If the runlevel is changed from a remote connection however, be advised that your connection will be lost if the network interfaces are shut down as a result of the runlevel change. [JMH]

The ASUS My Cinema-U3100-Mini is compatible (as long as you have a recent kernel) and is about $59.

No, Linux has .so (Shared object) and .ko (Driver) files.

Shared objects work in much the same way as dynamically linked libraries, except in a much better way that doesn't screw things up. There is no real Linux "DLL hell" equivalent.

+ adds a permission, - removes it, so +r and -w

Or by octal values. 4 sets read, 2 sets write, 1 sets execute . They are additive, each of the 3 digits referring respectively to the user, his group, and everyone.

So 400 means the user can only read the file, no one else can do anything

777 means anyone can do anything to it

744 means the user can do anything, all others can only read it

yes you can

Most Linux distributions will come with SSH preinstalled. If it's not, install the package "ssh".

Linus Torvalds is the creator of Linux. That won't change even if he were to step down and never touch Linux source again, he still created Linux in 1991.

If you mean who is now in charge of Linux, that's still Linus Torvalds. The only difference now is he's no longer the single biggest contributor to the kernel, although it has been pointed out that among individual people as contributors, he contributed the most, but the vast majority of kernel code now is written by companies like IBM, Red Hat, Intel, HP, and the like.

Linus will still generally have to approve anything going on with the core kernel itself, thus even a megacorporation like IBM still has to wait for him to approve patches, though he'll be one of a few core kernel developers who'l sign off on the code.

Any time a super user is logged on, changes can be made to files, sometimes without additional warning or approval. This could spell disaster for the file system or computer.

Displays the detailed status of a particular file or a file system.

You can always refer manual pages for linux commands using the terminal using the "man" keyword before the actual command.

ex:- man stat

Suse Linux is a software company, as it the distributor of the Linux operating system. It was established in 1992 and is part of the Suse Linux Enterprise.

"r" is not a standard command on Linux systems. Some systems may included or provide support for the R programming language, in which case the command would launch the "littler" program to run R commands included in the file 12.

The Linux equivalent of LPT1 is /dev/lp0.
