history of the linux operating system

Linux or GNU / Linux is a free operating system that is very popular for computer, term Linux or GNU / Linux (GNU) was also used as a reference to the whole Linux distro (Linux distribution), in which other programs supplied supporting operating system. Examples of such programs are web servers, programming languages, databases, desktop (Desktop Environment) (such as GNOME and KDE), and office applications (office suite), such as OpenOffice.org, KOffice, Abiword, Gnumeric. Linux Distro has experienced rapid growth in terms of popularity, making it more popular than the version of UNIX that uses a licensing system and paid (proprietary) or other free UNIX version that was originally to match the dominance of Microsoft Windows in some aspects. It supports a lot of computer hardware, and has been used in various devices from personal computers, supercomputers and embedded systems (embedded systems), such as mobile phones (Mobile) and personal video recorder. Initially, Linux was made, developed, and used by the devotees only. Linux now has support from major companies such as IBM and Hewlett-Packard. Analysts believe the success of information technology is because Linux does not depend on the vendor (vendor independence), low operating costs and high compatibility than proprietary versions of UNIX, as well as the safety and stability compared with Microsoft Windows. These characteristics are also a testament to the excellence model of the development of open source software (open source software).
 
Linux is widely distributed for free under the GNU General Publi License (GPL), which means the source code of Linux is also available to the public. Linux is developed by individuals and voluntary groups. Linux developers take advantage of the Internet to conduct the exchange code, report bugs, and fix any problems. Anyone interested in the development of Linux used to join this. The development of Linux was first performed by the Linux Benedict Torvalds in 1991 at the University of Helsinki, Finland. Then Linux is developed further with the help of many UNIX programmers and experts on the Internet. Linux can be obtained from several commonly used distributions, such as RedHat, Debian, Slackware, Caldera, Stampede Linux, TurboLinux and others.History of Linux

 UNIX is an operating system that started the birth of Linux to the world. UNIX is an operating system that exists today. The UNIX is a popular operating system other than Microsoft's giant family (ranging from DOS, MS 9x to Vista), Novell, OS / 2, BeOS, MacOS and other.
 
Emergence of UNIX history began in 1965 when scientists from Bell Labs, a laboratory owned by AT & T, in collaboration with MIT and General Electric made the operating system called Multics ('ve ever heard?). Well, the Multics operating system was originally designed with the hope of creating some advantages, such as multiuser, multiprocessor, and multilevel filesystem. However, in 1969, AT & T finally stop making project because Multics Multics operating system is no longer fulfill its original purpose. In other words, the project has run into difficulty because in reality there are many bugs Multics and difficult to operateLinus Torvalds know right? Linus was born in Helsinki, Finland on December 28, 1969. The person referred to as the father of Linux (Linus Unix), already familiar programming language at the age of 10. At that time he frequently tamper with computers grandfather, Commodore VIC-20. Because of his hobby in the world of computing, 1988 Linus accepted at Univerity of Helsinki and in 1990, Linus launch its first C programming class. In 1991, Linus was not satisfied with the existing operating system on the first PC (MS-DOS or Disk Operation System), OS made by Microsoft.Linus is more likely to use the UNIX operating system as used in the university's computers. Eventually he changed the Minix operating system open source UNIX-based. The Minix is ​​a small UNIX system developed by Andrew S. Tanenbaum, a professor who studies concerned with the problem of OS Vrije Universiteit, The Netherlands. The Minix is ​​used for teaching and educationBut Linus feels that Minix still has many weaknesses. And from then on, at the age of 23, Linus started tinkering Minix kernel. And he began to develop a system that is compatible with the IBM PC. In August 1991, Linux was born 0:01 oprekan Linus results, and on October 5, 1991, it was officially announced Linux Linus 0:02 which can only run BASH and gcc compiler. In addition, Linus also publish the operating system complete with homemadesource code, which was greeted with great enthusiasm by programmers and developers around the world in order to develop togetherUntil now, Linux is built by a variety of community and do not be surprised if a lot of Linux distributions in circulation. Starting from paid to free, from beginner to advanced to, and usually with a number of Linux distributions in circulation will make people confused to choose the distro. Imagine, there are hundreds of distros that are created or even thousands. However, slowly but surely, among Linux distributions there is an equal (or even) exceeds the ability of the giant family Operating System (Microsoft) and with the easy and the more complete hardware support on Linux, Linux would be the most likely alternative (or even system major operations in the world). Hopefully if there is no obstacle, I will give you tips on choosing Linux distro.Excess linux1. Linux is a free and open operating system. That is to say, there is no license fee for buying or using Linux.2. Linux is easy to use. First, Linux is an operating system that is said to be difficult and only devoted to the hackers. Now, however, this view is wrong. Linux is easy to use and can be said to be almost as easy as using Windows.3. Almost all of the applications contained in Windows, there have been alternative in Linux. We can access the web site Open Source as Alternative to obtain information that is quite useful and fairly complete information about alternative Windows applications on Linux.4. Security is superior to Windows. It can be said, almost all Windows users must have a virus, spyware, trojan, adware, etc.. It almost did not happen on Linux. Where, Linux was designed from the start of multi-user, which is when the virus infects a particular user, it will be very very difficult to infect and spread to other users. On Windows, this is not the case. So that when viewed from the side maintenance / maintenance-data and hardware would be more efficient. Articles that support this argument: 1. Linux and Viruses. 2. Protecting Windows from viruses by using Linux.5. Linux is relatively stable. Computers that run on UNIX operating system are well known stable running nonstop. Linux, which is a variant of UNIX, also inherit this stability. Rarelyencountered, the computer suddenly hangs and have to press Ctrl-Alt-Del or Restart to end the incident. Thus, it is not surprising that Linux has the world's server market share significantly. Drawing on research from IDC, worldwide server market that use Linux in 2008 will reach 25.7% (readable on eweek.com).6. Linux has backwards compatibility better (better backward-compatibilty). Hardware (hardware) that have been aged longer, it is still very useful and can run well on Linux. Old computers need not be removed and can still be used for certain purposes by using Linux (as supporting information can read the article "Do not Throw Away That Old PC-Give It New Life with Linux"). Other than that, never seen the documents that later can not be read on older versions of Linux. On Windows, if we are required to keep track of the hardware. For example, several months ago, has released Windows Vista. Some of the documents created in Windows Vista can not be opened in Windows XP. So, like it or not, we have to switch to Windows Vista, and that means to upgrade or purchase hardware (hardware) has a better (Windows Vista Minimum hardware can be seen Microsoft.com). Alternatively, there may be applications that were made a few years ago can not be opened anymore in Windows Vista, because it is no longer supported by Microsoft.

Disadvantages of Linux 

1. Many users are not familiar with Linux and still 'Windows minded'. This can be overcome with training or education to users so getting used to Linux.2. Hardware support from the vendors that were not too good on Linux. To find a list of supported hardware on Linux, we can look at the Linux-Drivers.org or LinuxHardware.org.3. The installation process software / applications that are not as easy in Windows. Installing software on Linux, it will become easier when connected to the internet or when having a CD / DVD repository him. If not, then we have to download one package is needed along with its dependencies.4. For system administrators who are not familiar with Unix-like (such as Linux), it will inevitably have to learn this. So the requirement is to be human administrator who enjoys learning new things and constantly learning.
