Whenever we are considering the computer for computing then the concept of Operating system is also come into our consideration. Merely the operating system is a software that enables the communication between computer hardware and software. It is used to make the hardware of the system useable. It conveys input to get processed by the processor and brings output to the hardware to display it. 

What is Linux?

  1. The Linux is an open-source operating system like other operating systems such as Microsoft Windows, Apple Mac OS, iOS, Google android, etc. 

  2. It is broadly used to denotes a complete family of free and open-source software operating system (for which we need not require to pay anything) distributions. 

  3. These are completely get built around the Linux kernel. 

  4. It was first started as a clone of the MINIX operating system. In order to bring such things feasible, some Open-source contributors are going to add the kernel of Linux and side by side they also expanded the feature of the hardware compatibility. 

  5. So, the most important and reliable feature of Linux’s hardware is that it can support much hardware without having any compatibility issues and they are free. 

  6. So, the free licensing made the Linux to become more popular choice for everyone for desktop and server computing.

  7. It can be used from wristwatches to supercomputers. 

  8. It is very effective and reliable, so it is being used everywhere in our day to day used devices like phones, laptops, PCs, cars and even in refrigerators.

  9. Since it is easily compatible with all hardware, so it is very much famous among developers and normal computer users.


  1. Like Linux the Unix is multi-tasking environment.

  2. It supports the concept of multi-user environment and hence it is also called as Multi user operating system.

  3. Like Linux it is not free to use and is not open source. 

  4. It was developed in 1969 by Ken Thompson team at AT&T Bell Labs. 

  5. Due to its better functionality like similar to Linux It is widely used on servers, workstations etc.

Difference Between Linux and Unix:



It is a is open source, freely available.

The Unix is not open source, and it is a licensed OS. Unix was initially a command-based OS.

It was developed by Linux community of developers.

Unix was developed by AT&T Bell labs.

It is basically used to support the file system like Ext2, Ext3, Ext4, Jfs, ReiserFS, Xfs, Btrfs, FAT, FAT32, NTFS.

It is used to support the file system like fs, gpfs, hfs, hfs+, ufs, xfs, zfs.

The Linux is being used in wide varieties of platforms and devices ranging from desktop, servers, smartphones to mainframes.

Unlike Linux the Unix is mostly used for servers, workstations, or PCs only.

Linux was initially developed for Intel's x86 hardware processors

CUnix supports PA-RISC and Itanium family.

Linux does have the Bash (Bourne Again SHell) as default shell.

Bourne Shell is default shell for Unix also.

It is used to support many GUI like LXDE, Xfce, Unity, Mate.

Most of the Unix distributions contains Gnome.

The most common version of Linux is Ubuntu, Debian GNU, Arch Linux, etc.

The most common version of Unix is SunOS, Solaris, SCO UNIX, AIX, HP/UX, ULTRIX etc.

Limitations of Linux:

  1. The major limitation in Linux is that it has no standard edition of Linux.

  2. It has basically a patchier support for most of its drivers which may result in misfunctioning of the entire system.

  3. For beginners, the complete gripping on commands for Linux is bit difficult.

  4. Many of the programs that we are using for Windows applications will only run-on Linux.

  5. It supports the concept of a complicated emulator. For example. Microsoft Office.

Limitations of Unix:

  1. Like Linux it is not so much user friendly.

  2. It has basically terse, inconsistent, and non-mnemonic user interface.

  3. Unix OS is designed for a slow computer system, so here the fast performance is usually not possible.

  4. As it supports the concept of Shell interface so if a programmer did some typing mistake then it can destroy files.

  5. Versions on various machines are slightly different, so it lacks consistency.

  6. Unix does not provide any assured hardware interrupt response time.

  7. It does not support real time response time systems.
