difference between unix and linux?

linux:

• Linux is an example of Open Source software development and Free Operating System (OS).
• 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.
• Everyone. From home users to developers and computer enthusiasts alike.
• Linux kernel is developed by the community. Linus Torvalds oversees things.
• 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.
• 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.
• Linux typically provides two GUIs, KDE and Gnome. But there are millions of alternatives such as LXDE, Xfce, Unity, Mate, twm, ect.
• Ext2, Ext3, Ext4, Jfs, ReiserFS, Xfs, Btrfs, FAT, FAT32, NTFS
• BASH (Bourne Again SHell) is the Linux default shell. It can support multiple command interpreters.
• Free but support is available for a price.
• Linux has had about 60-100 viruses listed till date. None of them actively spreading nowadays.
• In case of Linux, threat detection and solution is very fast, as Linux is mainly community driven and whenever any Linux user posts any kind of threat, several developers start working on it from different parts of the world
• Dozens of different kinds.
• Ubuntu, Fedora, Red Hat, Debian, Archlinux, Android etc.
• Originally developed for Intel's x86 hardware, ports available for over two dozen CPU types including ARM
• 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

unix:

• Unix is an operating system that is very popular in universities, companies, big enterprises etc.
• Different flavors of Unix have different cost structures according to vendors
• 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
• Three bigest distributions are Solaris (Oracle), AIX (IBM) & HP-UX Hewlett Packard. And Apple Makes OSX, an unix based os..
• The UNIX operating system is used in internet servers, workstations & PCs. Backbone of the majority of finance infastructure and many 24x365 high availability solutions.
• Unix systems are divided into various other flavors, mostly developed by AT&T as well as various commercial vendors and non-profit organizations.
• Initially Unix was a command based OS, but later a GUI was created called Common Desktop Environment. Most distributions now ship with Gnome.
• jfs, gpfs, hfs, hfs+, ufs, xfs, zfs format
• Originally the Bourne Shell. Now it's compatible with many others including BASH, Korn & C.
• Some free for development use (Solaris) but support is available for a price.
• A rough estimate of UNIX viruses is between 85 -120 viruses reported till date.
• Because of the proprietary nature of the original Unix, users have to wait for a while, to get the proper bug fixing patch. But these are not as common.
• x86/x64, Sparc, Power, Itanium, PA-RISC, PowerPC and many others.
• OS X, Solaris, All Linux
• 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)
• 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.
