Ubuntu is one of the best Linux operating system which is nicely build and available for free. It contains almost every software of our daily computing need.
Ubuntu always has at least 2 live versions which is officially supported. Canonical releases a new Ubuntu in every 6 months. It can be widely divided in two types. First one comes with a support of 18 months. Second type comes with Long Term Support of 3 years. This type of Ubuntu versions are also known as Ubuntu LTS.
Most of the ubuntu versions are available in CD version but from Ubuntu 11.10 Canonical has released a DVD version which contains all the applications of a cd contains plus some other applications.
Now come to downloading it:
Ubuntu.com allows us to download 2 live version of ubuntu through various method. One LTS and one latest 18 month supported release. These downloads are available is ISO format which can be used as a Live CD or it can be used to create a bootable USB drive or Pendrive using a tiny application called PendriveLinux.
You may direct download the ISO or by torrent (p2p). I will recommend to use the torrent since it will provide you pausing and downloading can’t be corrupted. It could be best option for low speed internet connection. P2P is best way to downloading stuffs if your internet service provider (ISP) allows this.
Choosing the ISO Image?
Initially I thought that Ubuntu Desktop ISO and alternative ISO are same thing and it is just to maintain the Server load. But later I realize that both are different type of ISO!
The desktop iso (Link similar to: ubuntu-11.10-desktop-i386.iso.torrent) is used for Live CD and can’t be used for upgrading existing install. Whereas Alternative ISO (Link similar to: ubuntu-11.10-alternate-i386.iso.torrent) is used for Upgrading an existing ubuntu install and can’t be used as Live CD.
It is also suggested that if your system supports 64-bit and using some high RAM then download 64-bit image. It will provide You better performance than a 32-bit operating system. But, If you have your system support 64-bit and you do not have a big RAM installed then it will be better to use a 32-bit OS. So, Choosing the right ISO is also important.
