What is Linux.

Linux is an operating system in that sense.

It's not unlike Microsoft Windows or Mac OS X Linux however is open source.

Open source does not always mean that it's free from paid licensing.

If you want to use Red Hat Enterprise Linux or Susa Linux Enterprise Server for example you'll have

to pay who booed you however whether you're using the desktop or server is totally free an operating

system is simply a platform upon which you may do your work or upon which your server may do its work.

Users interact with applications applications interact with the operating system and the operating system

lets both of them interact with the hardware the operating system itself lets you and your applications

effectively use the hardware to do what you want done if designed well an operating system hides many

of the complexities of dealing with hardware presenting a clean intuitive interface for you to use boon

to is a well-designed operating system it's intuitive complete and easy to learn Linux is actually suite

of programs fundamentally built on a new Linux can use the operating system with Linux as its kernel

the core or engine of the operating system.

Both are designed to emulate the proprietary Unix operating system designed by AT&T Bell Labs in the

1970s

Richard Stallman started the new project in 1983.

He wanted to design a pre operating system based on Unix to project had a kernel called good new heard

but it never gained enough popularity to become fully developed part of the project.

However it was also an open source license called the new General Public License or GPL.

This is an important development for Linux as it paved the way for the pioneers who made operating systems

that are open to all of us.

Linus Torvalds released an open source kernel under the GPL which is now known as the Linux kernel the

open source good new operating system now had an open source kernel to run on the open source kernel

and the open source operating system were joined together to give us a complete operating system.

We'll talk more in a later lesson about the Ubuntu distribution or distro.
