What is linux?

Linux is UNIX like operating system that evolved from a kernel created by Linus Torvalds in early 90’s. Later People all over the world decided to take him up on it and they all contributed codes to develop it more and more. Since it’s open source(anyone can view it’s source code and edit it), it’s development started as an open community and eventually it became better and stable.

Linux vs. Windows

Here I am listing some basic points about linux vs. windows. After reading these you will get to know everything whether you should use linux or not.



  • Reliability – The majority of linux variants are very much reliable as compared to can run into issues while running a windows os like it might get slow with time, BSD(blue screen of death), stability issues, it might need a restart after sometime after installing update or software, it might get hanged when something unexpected happens. But till now I haven’t seen any such kind of problem in linux. once installed it can run for years without a single reboot. it only needs a reboot after a kernel update(and that’s very rare) and the biggest factor is that it never slows down.
  • ease of use – When it comes to the factor of ease of use then the windows definately gets a hands up. i do not mean that linux is very hard to use. generally people have a common misconception that linux is only for geeks, but it’s not really true. It was true some years ago but now with the improved version of GUI in latest linux distros, it’s very easy to use linux. It has become more user friendly. But still when you got to compare it with windows, windows still much ahead than linux in terms of ease of use.
  • virus free – No windows platform viruses or trojans will run in linux. it means you can relax that you are not going to be ever get attacked by any kind of nasty viruses.
  • price – Linux is open source and most of the linux distros are available free of cost on internet while some of them may cost a minimal fee. whereas windows users have to pay 50$ – 150$ for a single license. yeah, its a different fact that most of us use windows for free but remember that’s a pirated version or cracked version and it may contain backdoors which can later introduce various malicious viruses or trojans in your pc.
  • support – Although it may be more difficult to find users familiar with all Linux variants, there are vast amounts of available online documentation and help, available books, and support available for Linux. Microsoft Windows includes its own help section, has vast amount of available online documentation and help, as well as books on each of the versions of Windows. It’s a little easier to troubleshoot windows in compariaon to linux.
  • security – Linux is and has always been a very secure operating system. Although it still can be attacked when compared to Windows, it much more secure. Although Microsoft has made great improvements over the years with security on their operating system, their operating system continues to be the most vulnerable to viruses and other attacks.
  • Hardware(drivers) – Windows has got a much greater support for many hardware devices because of greater amount of windows users. although linux supports almost all hardware devices it still does not support each and every hardware out there in the market. one other great feature of linux is that one does not have to install drivers in it after connecting any piece of hardware. if it’s supported it will automatically detect it. its real plug and play. and that’s a hectic task in windows.
  • software – Linux has a large variety of available software programs, utilities, and games. However, Windows has a much larger selection of available software.Because of the large amount of Microsoft Windows users, there is a much larger selection of available software programs, utilities, and games for Windows.
  • open source – Many of the Linux variants and many Linux programs are open source and enable users to customize or modify the code however they want to.Microsoft Windows is not open source and the majority of Windows programs are not open source.
  • Minimal hardware requirement – linux require very minimal hardware requirement to operate upon whereas latest windows versions require much greater hardware requirement.

My personal review

At the bottom line i would say that I am not exactly a linux fanboy until and unless the topic comes over establishing networks/servers or penetration testing any network and maintaining a hassle free and virus free computer. For playing games and working with windows apps, i feel good with my windows os.
If you are a very general computer user, you love games and often work with multimedia content or dont want to type any commands over the terminal then linux is not for you. but personally i would say, atleast give it a try and you may fall in love with it as I did 🙂
