Understanding of Linux by rizkydar125


									Lunch companions all? how's this afternoon, in the middle of the queue waiting for service the
motor, I want ya mosting about linux, what the heck is it linux? here we will berkanalan closer to
linux immediately wrote yah ...: D

1. What is Linux/UNIX?
Linux is widely recognized as the name of the computer operating system, ranging from large
computers (mainframes), servers, desktops, notebooks, netbooks, to PDAs and mobile phones.
First (1991) when Linux first made by Linus Torvalds just a Linux kernel or Linux operating
system core. Today, the name Linux is not only for operating systems, but also a collection of
programs packaged in single or multiple CD / DVD. Another term for a CD / DVD Linux is a
Linux distribution.

2. What is the Linux Distro??
Distributions derived from the word distribution which means the place or the means to deploy
Linux. Linux distributions are made by individuals or organizations, profit or non-profit oriented.
Examples of distributions:
Made individuals: Knoppix, Zencafe (Linux for the needs of the cafe and offices), briker (Linux
for VoIP), and others.
 Non-profit organization created: the Archipelago, Ubuntu (both for education, government,
offices), Fedora, Debian (both to the public), and others.
Made by a company: Ubuntu (Canonical, Inc.), Mandriva (also provides a version of the Free),
RedHat (supports Fedora), SUSE (Novel, which also makes openSUSE), and others.

3. What similarities and differences of each Distro?
Each distro has its own advantages and disadvantages when compared to other distributions.
Each distro also have in common, for example using the Linux kernel, so there is a single term
bhinneka kernel. The difference between the others in the packaging (a CD / DVD, a CD /
DVD), installation (there are Live-CD/DVD without having to install and difficult to install,
there Live-CD/DVD which can be installed, no CD / DVD installer which should installed
before use, and there is a form or can be converted into a stick, etc.).

4. Why did not / do not exist Distro Windows?
 Windows is not free software / free and not open source or FOSS (Free / Open Source
Software), so it may not be altered or modified and distributed, even should not be used without
permission (a license to use or pay licensing fees). Linux distributions can be made, or packaged
in a CD / DVD along with many other FOSS programs, while Windows can not be packaged
with other programs without paying for permission from the author.

5. What is FOSS?
FOSS stands for a combination of Free Software and Open Source Software. Free here means
freedom or free / independent. There is also a FLOSS (Free / Libre / Open Source Software),
which means the same. There are four freedoms of Free Software, which is free to use it for
anything, free to learn how it works, duplicate-free, and free to develop and disseminate results.
Free Software by Richard Stallman coined by the Free Software Foundation was at about 1984
The term Open Source Software is already inherent in Free Software, ie the availability of source
code (source code) that can be studied and developed further. But Eric S. Raymond and Bruce
Perens founded the open source movement by the name of the Open Source Initiative at around
1998 (www.opensource.org) to avoid the word Free is often mistaken for free. So, Free Software
and Open Source Software is a two-term goal is the same, namely the freedom to use, study,
develop, and disseminate software, by way of paid or not paid.

6. Does FOSS is Free?
No, unless the license. Free does not always mean free, because almost all elements of the
software it is necessary fees to acquire, use, study, develop, and disseminate it. Are free of Free
Software is a letter of permission or license. Free license means no need to charge license to use,
modify or develop, and copy or disseminate. FOSS can be commercialized or used as a business.
Could have cost to get the software on CD / DVD or downloaded from the internet. Similarly, it
would cost to learn, such as buying a book or training.
Costs also need to develop, such as paying staff programmers. And necessary costs for
distribution, such as rental fees or server on the internet and send a CD / DVD. The term for free
software is Freeware, which is not necessarily available program source code (open source).
While the Free Software must be open source.

7. What is Linux free?
No, except a license. FOSS license that the Linux kernel, but Linux distributions have a license
and there are some FOSS FOSS. Examples of FOSS Linux distributions: Debian, Ubuntu,
Fedora, openSUSE, and others. Examples of distributions that are not fully FOSS: RedHat
Enterprise Linux (there should not be disseminated without permission of Red Hat Inc..), SUSE
Linux Enterprise, etc.. Although there are companies that distribute CD / DVD for free Linux
distributions, Linux still should not be called free software because Linux is not Freeware. The
company that financed the manufacture of CD / DVD and its distribution. That is really free is
the license the Linux kernel and many FOSS programs on the CD / DVD distro of Linux.

8. Is Linux License will continue to Free?
Yes. License Linux kernel and many programs in Linux distributions is FOSS, with the name of
the GPL (GNU General Public License) or similar. FOSS licenses like the GPL does not allow
changes to the license. Software may be modified, must remain GPL license.

9. What is the Disadvantages and Advantages of Linux?
Disadvantages of Linux there is one: not supported MicroSoft and several maker software /
hardware. Advantages of Linux there are five: free of viruses (relatively safe compared to
Windows), free sweeping (more appreciative of Intellectual Property Rights), free of wasteful
(overall cost is lower, though not free), free of dependency (such as drug free), and free to hell
(plowing software is forbidden).
