ubuntu-12.04

I've been using ubuntu 12.04 for 3 weeks. Today it become unresponsive and I lost stuff I was working on, I had the hand displayed, as if I selected something but in fact never did, but was reading an article online. I finally powered down the machine and then turned it back on. In windows there is the Task Manager where one can see whats taking up all your CPU or RAM, is there a such a program in ubuntu 12.04 and if not, can I install a app that has the same use?
