I want to begin using linux because i work in bioinformatics and need open source environment to work in it. I'm just confused which better version i should used and what are packages of bioinformatics i can use in linux system.
Biolinux - http://nebc.nerc.ac.uk/tools/bio-linux/bio-linux-7-info is built on Ubuntu and will give you a large number of tools built in (with dependancies etc all taken care of).
It can be installed and run off a thumb drive if you do not want to install it on your current computer. Or get Oracle's free VirtualBox software and install it into a virtual machine on your current Windows or Apple OS X computer.
They are many flavours of Linux and all would do a great job. As a start the most friendly one is probably Ubuntu: http://www.ubuntu.com/. You can download a live CD and try it out without installing see if you like it.
As for bioinformatics most packages will work very well in Linux (bioperl, biopython, R etc...)
