Linux Architecture

Linux Architecture:




What Is Kernel & Shell:


  • Kernel - Kernel is main part of an O.S., Kernel is used to interact with hardware, manage I/O devices, manage resources like cpu, ram, hdd, etc,. & used to manage Processes.
  • Shell - Shell is a text based program. Users can only interact with shell, then shell interacts with kernel & finally kernel can interact with hardware.
Linux Kernels:
  • Linux Kernel is monolithic.
  • Traditional Unix kernels are compiled & linked statistically.
  • Kernel threading.
  • Multilevel application support.
  • Linux is a non-pre emptive kernel.
  • Multiprocessor support.

About Linux

What is Open Source Technology?

In today's world we often hear the term 'Open Source Software' but we really don't now what it actually is or the difference of it as compared to the earlier software. The fact is that we don't spend time in google to search and find out what this actually is. Well now i'll tell what is it.

According to me open source technology is entirely different as compared to the earlier software technologies. I think open source is like a new philosophy or a new technology in the 21st century. It completely changed my view of technology.

Before the idea of Open Source most of the softwares were depending on the idea of Closed Source. The softwares which follows the idea of Closed Software are called proprietary softwares. Eg: Microsoft Windows,etc. Open Source based software's are now developing into the field of technology.Eg: Linux, Ubuntu,etc.Now, what are the differences between open source and proprietary softwares?Proprietary software's are copy-write protected. the owner of a proprietary software restricts its use, modification of source code and redistribution. But open source softwares are free softwares. It source code is available to all and can be modified. It can also be distributed and copied.In fact open source opens a door to a new world of technology. Open Source creates a world where there is better quality, higher reliability, more flexibility, lower cost and an end to predatory vendor lock-in. It also promotes a connection of trust around the developers and users. For me being a part of this whole new world is a great thing. Open source developments are taking place every day. In this the developers and well as the users play an important role. Its good to have a software in our hand which could be redesigned as our wish. Just think about it!! So i hope you guys got a clear and precise picture of Open Source and its difference with proprietary software. 

History of Linux:
In 1991 a student linux TORVALDS develop a kernel with the help of unix programmer that is know as "LINUX".


Kernel + Shell + Application Software = Operating System


Features of Linux:
