Bookmark 3 / 7 Blog from Introduction to Linux Become a Certified Professional Linux is a Unix-clone written from scratch. But is that all that there is to it? In this Unix vs Linux article, we shall uncover what makes the two of these operating systems alike and different from one another.Minute intricacies make people choose amongst the two and while Unix has historically dominated the market, the demand for Linux Certified professionals has been on full throttle for the past couple of years.What is Unix?What is Linux?Difference between Unix and LinuxLimitations of UnixLimitations of LinuxUnix vs Linux: What is Unix?Unix is a proprietary operating system. It is a stable, multi-user, multi-tasking system for servers, desktops, and laptops. Unix is an OS which is popular in companies, universities, big enterprises, etc.This OS was born in the late 1960s at the ATT Bell Labs and was called Unix. Written in C, it allowed quicker modification, acceptance, and portability.What began as a one-man project under the leadership of Ken Thompson of Bell Labs went on to become one of the most widely used operating systems.The Unix OS worked initially on the Command Line Interface, but recently, there have been developments for GUI on Unix systems.Unix vs Linux:What is Linux?Linux is an open source, free to use operating system widely used for computer hardware and software, game development, tablet PCs, mainframes, etc.Linux was built by Linus Torvalds at the University of Helsinki in 1991 deriving its name from the Linux kernel.What made it stand out was the fact that it could be installed on various types of computers, mobile phones, tablets, video game consoles, etc.The development of Linux is one of the most prominent examples of free and open source software collaboration. Today many companies and similar numbers of individua ls have released their own version of OS based on the Linux Kernel, e.g. Apples iOS.Unix vs LinuxUsageUnix finds its use predominantly in internet servers and workstations whereas Linux can be used by everybody from beginners, to developers to mere enthusiasts, alike.Development DistributionUnix distributions are mostly developed by ATT and various commercial vendors and non-profit organizations. Linux, on the other hand, is developed by Open Source development and it is distributed by various vendors.ProcessorUnix is available on PA-RISC and Itanium machines supporting processors such as x86/x64, Sparc, Power, Itanium, PA-RISC, PowerPC, and many others.Linux, which was originally developed for Intels x86 hardware uses way more processors in number with ports available for several different CPU types.File System SupportUnix supports jfs, gpfs, hfs, hfs+, ufs, xfs, zfs formats whereas, Linux supports Ext2, Ext3, Ext4, Jfs, ReiserFS, Xfs, Btrfs, FAT, NTFS and many more.Shell Interfac eOriginally the Bourne Shell was Unixs default. Now its compatible with many others including BASH, Korn C. BASH (Bourne Again SHell) is the Linux default shell. It can support multiple command interpreters.Graphical User InterfaceInitially, Unix was a command-based OS, but later a GUI was created called Common Desktop Environment. Most distributions now ship with Gnome.Linux typically provides two GUIs, KDE Gnome. But there are millions of alternatives such as LXDE, Xfce, Unity, Mate, etc.PortabilityWhile Unix isnt portable, Linux is and can be booted using a USB stick, too.Security and Threat DetectionDue to 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. There are between 80 to 120 viruses reported till date in Unix.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. Linux has had about 60-100 viruses listed to date which are currently not spreading.Source CodeWhile there are distributions of the Unix tree which are open-source, like NetBSD, OpenBSD, and FreeBSD, Unix was developed by various vendors like IBM, HP, etc. for their business requirements. They wont distribute the source code to the public. So, Linux has been developed and the source code has been distributed to the public under GNU license.LicenseDifferent flavors of Unix have different cost structures according to their respective vendors.Linux is freely distributed, downloaded through magazines, Books, website, etc. There are paid versions as well but to be honest, theres very little distinction between the paid and unpaid distributions except for the support contract.Unix vs Linux | Linux Admin Certification Training | EdurekaThis Unix vs Linux Tutorial video will help you understand the basic differences between both of these operating systems while giving you an idea about each of the Operating Systems.Limitations of UnixUnixs interface is unfriendly, terse, inconsistent, and non-mnemonic to say the least.Unix OS isnt quite designed for fast performance.Shell interface can be treacherous because typing mistake can destroy files.Unixs versions lack overall consistency as it varies from machine to machine.Unix does not provide any assured hardware interrupt response time, so it does not support real-time response systems.Limitations of LinuxTheres no availability of any standard edition of LinuxLinux has patchier support for drivers which may result in misfunctioning of the entire system.Many of the programs exclusive to Windows only run on Linux only with the help of a complicated emulator. For example. Microsoft Office.Edurekas Linux Administration Certificationwill help you gain a strong foundation in Linux from scratch.
