Linux is a popular operating system, which is designed on the base of Linux Kernel. Linux is an open source system and which runs on multiple hardware platforms. The importance of using the Linux operating system is to provide free and less expensive operating services for users. Linux operating system is also considered as a user-friendly work nature which can be modified easily and also enables a user to create variations in the source code. Users can use this type of operating systems like Windows, MAC, Android, and IOS. This operating system always conveys the input data which is processed by the processors and brings them to the hardware for display purposes.
Linux is also distributed under an open source license. Open source follows these key tenants:
-
The freedom to run the program, for any purpose.
-
The freedom to study how the program works, and change it to make it do what you wish.
-
The freedom to redistribute copies so you can help your neighbor.
-
The freedom to distribute copies of your modified versions to others.
These points are crucial to understanding the community that works together to create the Linux platform. Without a doubt, Linux is an operating system that is ?by the people, for the people?. These tenants are also a main factor in why many people choose Linux. It?s about freedom and freedom of use and freedom of choice.

In 1991, while studying computer science at University of Helsinki, Linus Torvalds began a project that later became the Linux kernel. He wrote the program specifically for the hardware he was using and independent of an operating system because he wanted to use the functions of his new PC with an 80386 processor. Development was done on MINIX using the GNU C Compiler.
Unix is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.

- Linux can be freely distributed, downloaded freely, distributed through magazines, Books etc. There are priced versions for Linux also, but they are normally cheaper than Windows.
- Different flavors of Unix have different cost structures according to vendors
Linux is developed by Open Source development i.e. through sharing and collaboration of code and features through forums etc and it is distributed by various vendors.
Unix systems are divided into various other flavors, mostly developed by AT&T as well as various commercial vendors and non-profit organizations.
Linux kernel is developed by the community. Linus Torvalds oversees things.
Three bigest distributions are Solaris (Oracle), AIX (IBM) & HP-UX Hewlett Packard. And Apple Makes OSX, an unix based os..
Everyone. From home users to developers and computer enthusiasts alike.
Unix operating systems were developed mainly for mainframes, servers and workstations except OSX, Which is designed for everyone. The Unix environment and the client-server program model were essential elements in the development of the Internet
Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers and video game consoles, to mainframes and supercomputers.
The UNIX operating system is used in internet servers, workstations & PCs. Backbone of the majority of finance infastructure and many 24x365 high availability solutions.
Ext2, Ext3, Ext4, Jfs, ReiserFS, Xfs, Btrfs, FAT, FAT32, NTFS
jfs, gpfs, hfs, hfs+, ufs, xfs, zfs format
BASH (Bourne Again SHell) is the Linux default shell. It can support multiple command interpreters.
Originally the Bourne Shell. Now it's compatible with many others including BASH, Korn & C.
Linux is an example of Open Source software development and Free Operating System (OS).
Unix is an operating system that is very popular in universities, companies, big enterprises etc.
Linux typically provides two GUIs, KDE and Gnome. But there are millions of alternatives such as LXDE, Xfce, Unity, Mate, twm, ect.
Initially Unix was a command based OS, but later a GUI was created called Common Desktop Environment Most distributions now ship with Gnome.
Free but support is available for a price.
Some free for development use (Solaris) but support is available for a price.
Linux has had about 60-100 viruses listed till date. None of them actively spreading nowadays.
A rough estimate of UNIX viruses is between 85 -120 viruses reported till date.
Dozens of different kinds.
x86/x64, Sparc, Power, Itanium, PA-RISC, PowerPC and many others.
Ubuntu, Fedora, Red Hat, Debian, Archlinux, Android etc.
OS X, Solaris, All Linux
Originally developed for Intel's x86 hardware, ports available for over two dozen CPU types including ARM is available on PA-RISC and Itanium machines.
Solaris also available for x86/x64 based systems.OSX is PowerPC(10.0-10.5)/x86(10.4)/x64(10.5-10.8)
Inspired by MINIX (a Unix-like system) and eventually after adding many features of GUI, Drivers etc, Linus Torvalds developed the framework of the OS that became LINUX in 1992. The LINUX kernel was released on 17th September, 1991
In 1969, it was developed by a group of AT&T employees at Bell Labs and Dennis Ritchie. It was written in “C” language and was designed to be a portable, multi-tasking and multi-user system in a time-sharing configuration.
