Google being the best search engine till now as it has everything that you want to know. I am being a software professional without google I think it is very difficult to sustain in the software industry. Google contains all the information that you are required.
Only thing is that you should you appropriate keywords to get your work done. Anyone can learn anything from google without going out. Staring from Education to up-to date technologies you can learn from it. It has number of applications also including gmail, google maps etc
