Ubuntu is the operating system which comes in linux category.Its very complectated for user.Its not user friendly operating system.However, Its operating system very good work but if you have knowledge about Ubuntu linux other than its not good.Basically this OS use for hacking, Computer programming etc.Its features very complex from Windows 10, 8, 7, XP.Normal person can not use this operating system because its very typical for using.It can not easy to install in computer and its can not easy to use.However, its features are good but its very complex.Recently I used this ubuntu version 13 .1 but I have not proper used for this OS because I faced many problems like as related to the software installing, Network connectivity etc.Basically this OS good only for IT student and IT employee because they have some knowledge about this.Its main disadvantage its all hard drive format automatically in one partition during installation.So its not good normal daily users.
