what is Linux• Linux is a (os) operating system
•Os operating system (OS) is system software that manages computer hardware and software resources• Linux is, in simplest terms, an operating system. It is the
software on a computer that enables applications and the computer operator to access the devices on the computer to perform desired functions

History of linux• The History of Linux began in 1991 with the commencement
of a personal project by a Finnish student, Linus Torvalds, to create a new free operating system kernel

•Since then, the resulting Linux kernel has been marked by constant growth throughout its history. Since the initial release of its source code in 1991, it has grown from a small number of C files under a license prohibiting commercial distribution to the 3.10 version in 2013 with more than 16 million lines of source code under the GNU General Public License.

Why Linux • Free for download; no licensing issues or costs
• Freedom to share with anyone
• - Impervious to viruses
• Full suite of software applications
• Low resource use on hardware side

• Easy to use
• Available in almost any language
• Flexible: can be run on everything from watches to supercomputers
• The most important is that Linux is an open source project and its sourse code is not locked so any developer can make his own version of Linux and this versions called (distribution)

• Linux doesn’t need to be rebooted periodically to maintain performance levels• Linux provides persistent high performance on workstations and on networks.• The large number of Linux distributions gives you a choice. Each distribution is developed and supported by a different organization.
Linux continues work well even when the hard disk is almost full.
Linux is designed to do many things at the same time.

FALSE MYTHS ABOUT LINUX
Myth 1: Linux is too difficult for ordinary people to use
because it uses only text and requires programming.
Myth 2: Linux is less secure than Microsoft Windows
because the source code is available to anybody

Myth 3: It is not worth bothering to learn Linux because most companies use Microsoft Windows and thus a knowledge of Windows is desired for most jobs.
Myth 4: Linux cannot have much of a future because it is free and there is no way for businesses to make money from it.
Myth 5: Linux and other free software is a type of software piracy because much of it was copied from other operating systems.
