Describe a computer

Its second week of my post graduation course and one of the most talented professors here gives us 10 mins, saying "Describe a computer". The irony is we all know a stereotype answer for the question but no one out of 16o Mtech students was confident or satisfied with the answer he/she proposed. It is truly said(mentioned by another awesome prof here)

'when you think you know everything,you get bachelor's degree;

when you realize there is more to it,you get master's degree;

and when you say you know nothing,you get a phd' :-)

I always wanted to go for higher studies but I had a misconception, I used to think you learn 'a b c' in Btech and you learn 'cab' in Mtech. My life used to revolved a lot around studies and grades. It was studies that shaped my life in past. That one question by my prof about describing a computer suddenly opened new gates. Its not about knowing stuffs as written in a book, its about relating to it : feeling the science within.

I asked lot of students here why you are here and got the most obvious answer higher salary, even when I say out loud that I am here to learn more, I sound phony. hahaha. Every step you take in your life has a motive, some say when this motive is money it ruins the essence of job. Money or otherwise, if the driving factor is strong enough to make you follow the full path that you stepped on, then I guess its good enough.

I don't know where I am heading on with the above said, but I know one thing : strong determination is enough to achieve the goal, this goal can be money as well as knowledge.I am off to figure out a computer : -) still.
