As we know that vi editor has three modes namely: command mode,input mode & ex mode.By default,we get the command mode when the editor is evoked. Also we can navigate to other modes by using suitable commands like "i",":" etc. My problem is that when I press backspace in input mode,it doesn't erase the character unlike in the same editor that I have worked in RedHat does. I want to be clear about it.

If there isn't, you need to install vim using sudo apt-get install vim – i08in Sep 29 '13 at 9:07
@Jobin thanks again,but it requires internet connection,right? is there any way to do the same offline? – rosemary Sep 29 '13 at 9:10
