Linux Operating System And its Features

Spread the love

Linux Operating System is a free and open Source Operating System developed by Linus Torvalds and came into existence in the year 1991, at AT & T’s Bell Laboratories, released under the GPL (General Public License).  As any other OS main function of Linux OS is to manage the system resources (Hardware). We can refer it as an interface between the user and the computer system. GNU Linux has received lots of success and popularity in the last 2 decades with most of the commercial servers now using GNU Linux. Recently home users also started using Linux as their day to day OS, and popular Laptop and PC manufactures also giving GNU Linux as a pre-installed OS on their systems as its free and helps in cutting overall cost.

What type of OS is Linux?

Linux falls under the category of the Layered Architecture OS, consists of following layers:


  • Hardware layer – Hardware consists of all peripheral devices (RAM/ HDD/ CPU etc.).
  • Kernel – Core component of Operating System, for all basic input/output management it interacts directly with the hardware.
  • Shell/GCC – An interface between the user & the kernel, hiding the complexity of the kernel’s functions from users. Takes command from the user and executes kernel’s functions.
  • Application Software – Utility programs giving user most of the functionality of an operating system.
  • Users – System users, who interacts directly with the system and application software.

Important features of Linux Operating System

Basic Features

Following are some of the important features of Linux Operating System.

  • Portable – Portability means software can works on different types of hardware in the same way.Linux kernel and application programs support their installation on any kind of hardware platform.
  • Open Source – Linux source code is freely available and it is a community based development project. Multiple teams work in collaboration to enhance the capability of Linux operating system and it is continuously evolving.
  • Multi-User – Linux is a multiuser system means multiple users can access system resources like memory/ ram/ application programs at same time.
  • Multiprogramming – Linux is a multiprogramming system means multiple applications can run at same time.
  • Hierarchical File System – Linux provides a standard file structure in which system files/ user files are arranged.
  • Shell – Linux provides a special interpreter program which can be used to execute commands of the operating system. It can be used to do various types of operations, call application programs etc.
  • Security – Linux provides user security using authentication features like password protection/ controlled access to specific files/ encryption of data.

Linux is fast, free and easy to use, power laptops and servers around the world. Linux has many more features to amaze its users such as:

  • Live CD/USB: Almost all Linux distributions have Live CD/USB feature by which user can run/try the OS even without installing it on the system.
  • Graphical user interface (X Window System): People think that Linux is a command line OS, somewhere its true also but not necessarily, Linux have packages which can be installed to make the whole OS graphics based as Windows.
  • Support’s most national or customized keyboards: Linux is used worldwide and hence available in multiple languages, and supports most of their custom national keyboards.
  • Application Support: Linux has its own software repository from where users can download and install thousands of applications just by issuing a command in Linux Terminal or Shell. Linux can also run Windows applications if needed.

What Makes Linux So Popular?

Besides demand, Dell has chosen to use Linux on their machines because the software is so affordable, this means lower priced laptops to the public. The machines will be able to run faster and smoother than they do with Windows with less frustrating updates.

Linux offers a choice of benefits from affordability and flexibility to excellent packages including word processing, spreadsheets and more.

Once you get the hang of the Linux program it is really easy to use, those that have been using it for years will tell you it far outweighs Windows, but for Windows users it’s a little more complicated than that.

Linux machines enable you to ensure excellent reputation management online by tailoring your operating system to meet your specific demands. You can find out more information on these machines when you click for source.

Overall it has to be agreed that demand has brought these great operating system back to the Dell laptops, they couldn’t ignore the fact that their Linux machines were still selling and in high demand, yet they were not advertising them anymore, actually they stopped advertising them back in 2010 and yet they were still selling.

In order to keep up with the times, Dell has had to take the client demands into consideration before losing the power user side of the market. The same as you can test an example url, but it’s no use if you don’t have the specific target audience clicking on it.

It will be exciting to see how these new Linux Dell Laptops do and how well they sell once they are introduced onto the market.

The History of LINUX Operating System

The History of Linux began in 1991 with the beginning of a personal project by a Finland student Linus Torvalds to create a new free operating system kernel. Since then, the resulting Linux Kernel has been marked by constant growth throughout the history.
