Features of Linux OS

Linux OS is multiuser, multitasking operating system and portable to be installed on any hardware platform. Linux OS provides robut security features in comparative to other desktop operating systems. 

Linux operating system distributions in tree format

Linux Kernel was bundled with many others software packages from various distributors and named it there own distributions. We can see such distribution list in tree format.

Linux Distros Tree:

What are the Features of Linux?

  • Multitasking:
Linux OS is capable of running multiple applications and processes at the same time.
  • Multiuser : 
It means more than one user can shares the same system resources (hard disk,memory, printer, application software etc..) at the same time.
  • Portability:
Linux OS can be installed on all hardware architectures.
  • Reliability:
Linux OS servers are highly available and requires less downtime. And this enables small to large organizations to equip linux server for their application hostings. 
  • Security: 
Linux OS provides robut security features in comparative to other desktop operating systems particularly - windows operating system. For example,
Linux servers are more insulated to viruses than its counter part windows.
Email attachments are not directly executable in  linux machines.
  • Clustering:
Multiple linux servers can be harnessed as part of high performance cluster. This provides highly available application services during hardware failures on any box.

OS - What is an operating system

An operating system is a software which acts as an interface between the user and the hardware. Commonly used operating systems are Windows, MAC- osX, UNIX/Linux.

What are the Functions of an operating system?

  • Booting the system.
  • Managing the basic computer tasks like managing various peripherals for example mouse and keyboard.
  • Provides user interface like CLI (command line interface) and GUI (Graphical user interface).
  • Handles system resources such as computer's memory and sharing of the central processing unit (CPU).

What is Hardware?

Hardware comprises of physical devices like CPU, Monitor, printer, mouse etc.,
The user can perform several tasks on hardware using the operating system. This shows that the operating system is an interface between the user and the hardware.

The process of accessing the hardware.

Note: 
Above mentioned are a couple of operating systems that we know so far and a couple we might encounter over a period in IT industry.
There are other operating systems like RTOS,VXWorksetc..Wedin’tspecify here.

In this tutorial, we are going to focus more on Linux based operating systems for enterprise servers.
