What are the advantages of SUSE Linux?
The only real advantage of SUSE Linux over other distros IMO is that windows users could install it and not be too lost. Although some other Linux OS are nearly as easy to use as SUSE now.
What is Linux Virtualization software used for?
Linux Visualization software allows a single host computer to create and run one or more virtual environments. For example it allows Linux to run as a guest on top of a PC that is running a Microsoft Windows operating system.
How do you recover your password for Linux on the Acer Aspire One?
You can't recover passwords in Linux; you can only reset the passwords on various accounts.
How do you back up an Informix database in Linux?
Ontape or Onbar back utilities. You can backup to a disk file or to a tape device.
Onbar requires a storage manager like Tivoli or Netbackup.
What is best antivirus software for Xubuntu?
Linux does not need antiviruses.
It doesn't as much as windows, but it is possible for you get a virus on this system. Avast has a version for Ubuntu and its branches of distros.

How do you mount Linux partitions in Windows?
Mounting NTFS partitions in Linux is fairly simple. You will need to download and install the appropriate NTFS driver for your distribution. I would suggest (at the time of writing this) NTFS-3G (http://www.ntfs-3g.org). It has stable read/write abilities. You can do this by downloading the appropriate RPM/DEB file and running the install command, or possibly using your distribution's package manager to do this for you.
Once you have the package installed, most of the work is done for you. You mount it using normal mounting commands:
1. List the partitions known to the system (`more /proc/partitions`) and determine which one is the target.
2. Create a mount point for your NTFS partition (`mkdir /mount/ntfs-drive`, for example).
3. Issue the mount command (ex. `mount -t ntfs /dev/sda1 /mount/ntfs-drive`).
Be aware that the NTFS system is an intricate part of the Windows NT subsystem - if you modify a lot of files, the wrong system file, program file, database file, etc, the filesystem metadata may change and prevent it from working in Windows NT (I've never experienced this but I would never do it on an important machine). In short, read all you want, write whenever you need, but be careful if you do anything really intricate with Windows system files.
When was Linux first introduced?
It was created and finally released to the public in 1991, where it underwent heavy development until it reached 1.0 in 1994. Its current version, 2.6, was released in 2003, though due to its new version scheme, one could almost consider the current Linux kernel an almost 3.x or 4.x if it stuck with its old scheme.
How do you install zsnes on Linux?
The answer to this really depends on what operating system that you use:
Try the following commands:
emerge zsnes
apt-get install znes
yum install zsnes
pacman -S zsnes
For gentoo, debian, redhat, and arch based distributions respectively.
Alternatively, your distribution might include a software manager. Search your applications for store, software, synaptic, package manager, etc.
Program in shell of implementing cp command?
The 'cp' command is a primitive command; there isn't anything really in the shell to accomplish this. You could use other commands for 'cp' (such as 'cat') but those are also primitive commands.
Can An emulation card can be added to a Macintosh that allows it to run Windows programs?
It is possible, theoretically, yes, but that was long ago.
Use an Intel Mac or if you have an older or PPC (Power-PC, now called Power-ISA),
You can get something called Q(Emulator) which allows for running Windows (aka; 'Win32') Programs on a Mac (non-Intel) computer.
They call it Q or Qemu, either way do a quick Google search, you can find it all over the web and ._t.o.r.r.e.n.t*s too.
(T0rrents can be highly illegal in a way, especially if you use them to download movies without paying, or payed software free, etc. It all depends on what you use them for. Many places consider torrents to be taboo, so I highly indulge you to keep away from this option, only use it as a last resort)!

What lab was Linux developed in?
Linux wasn't developed in a lab. It was developed a number of places, starting in Linus Torvald's apartment.
What does the command sort file 1 file 2 do in Linux?
Try this in the terminal:
man sort
and
sort -?
Reading it for yourself is the best way to learn.
How do you schedule backups to run automatically.?
This is in Linux. You can schedule your backup scripts to run automatically through "cron jobs". The cron job must be in the /etc/crontab file. Example crontab format:-MINUTE HOUR DAY of MONTH MONTH DAY of WEEK COMMANDRanges are;MINUTES: 0-59, HOUR: 0-23, DAY of MONTH: 1-31, MONTH: 1-12 or JAN-DEC, DAY of WEEK: 0-6 or SUN-SATNote: The COMMAND can be a single command, multiple commands separated by ";" and/or "&&" or a path to an executable shell script. In systemd you will not find "cronjobs", instead there are "timers". "timer"s are systemd unit files whose name ends in ".timer". Each ".timer" file controls a ".service" file. For an example, if a run.timer file is found, there is a corresponding run.service file. These "timers" can activate on a calendar event (Realtime Timers) (like cronjobs) and activate after a time span (Monotonic Timers).Default timer and service file location in arch linux: /usr/lib/systemd/system
How would you find the IP address of examplecom from the command line?
Instructions on Tracert
Click on the "Start" menu.
Type "cmd" in the "Run" text box on a Windows XP computer. Type "command" in the "Search" text box on a Windows Vista or Windows 7 computer. This will open a window allowing you to access the command prompt.
Type the command "tracert www.example.com" to locate the IP address of the site. Replace "www.example.com" with the URL (Uniform Resource Locator) of the website you want the IP address of. The first line of the output will say "Tracing route to www.example.com [IP address]". The IP address of the website is between the brackets.
Type "exit" to close the window.

Can you provide a Linux shell script that prints the current user ID?
#/bin/bash
export UNAME=`whoami`
export USERID=`id -u $UNAME`
echo $USERID
Is it possible to execute two os windows and Linux?
Yes. There are two ways to do it. You can dual boot, which is installing both operating systems at the same time on the computer. When you start the computer, it'll ask you which operating system to boot.
The other method is with a virtual machine. This will allow you to run the second operating system inside of the first one. It's much simpler to set up a virtual machine than it is to dual boot operating systems.
What does a network manager do?
If your are referring to the managerial role of a person in network management, a manager is a person that is part of a network management organization. This person is responsible for monitoring, configuring, and adjusting the various aspects of network equipment (elements) and the services and applications supported by a network .

What are Linux licensing issues?
Linux is licensed under the GPL. This means that if you use the kernel in one of your products, you must release any changes that you made. You can use proprietary modules, but these are restricted in what they are allowed to do. Only freely licensed modules can access all features of the kernel.
How do you locate lines beginning and ending with a dot using sed?
grep can match the beginning of a line with the '^' character and the end of a line with the '$' character. Any character is matched by the '.' character, so to match a literal "." you will need to use the escaped '\.' sequence. Thus to match a line beginning with a dot and ending with a dot you would use:
Generally accepted to be the Linux Foundation, which is located in San Francisco, Tokyo, and Seoul.
However, Linux development is such that Linux itself is not really developed in any one place. Every Linux distributor is headquartered somewhere else, and most contributors to Linux aren't part of the Linux Foundation.
What is different between RPM and yum command of Linux?
RPM is the extraction / installation component. YUM is the downloader. If RPM is run to install a package without its dependencies already installed, it will fail. YUM's job is to download all necessary dependencies.
Linux is just the kernel.
If you combine utilities that were made as a result of the GNU project with the linux kernel, you get GNU Linux, which is considered as a complete operating system
