grandpa i'm a computer science engineer

whenever I tell my relatives particularly the ones who are of my grandfather's age that I'm doing engineering, they are very impressed. they say "oh you are doing engineering. that's wonderful. which branch?" when they hear computer science , they look a little confused and then ask "what do u learn in that?" In layman terms, I say I learn about computers. and so next time the computer in our house breaks down, I am summoned and told to look into it. They say "you are a computer science engineer na ...see what has happened to the computer, it is not starting"

and that's an embarrassing situation for me......come on we are not taught how to repair the computer in college, we are taught how to work on them.......and so when i say " oh i can't repair it" They are astonished "but you are a computer science engineer. aren't you? don't they teach you all that in engineering?"

the other day, my aunt wanted me fix the television when it wasn't working and was disappointed that being an engineer i couldn't do it. Another big dilemma that my relatives face is .....what is the difference between IT and CSE? ........I have tried differentiating them ....but it always come downs to the same thing that we both work on computers....

but recently when i had to give a mock interview ....and i was asked these same questions ......
well friends, i fumbled ...and mumbled something but couldn't give a good answer....well now many of us are going to face interviews for jobs for MBA .... maybe its time to find a proper answer well here's what i found in wiki answers which i liked ---

Best way to visualize it is imagining an up side down pyramid.

level 1 - chip design level which uses devices to make integrated circuits, power electronics. This is area of Electrical Engineering.

level 2- Computer Science where computer scientist know the circuits/hardware that exist and develop solutions to incorporate it.For example when multi core processors were developed, the computer science people had to develop code to work on multiple cores. they had no knowledge of how the registers work in a cpu...but they have knowledge on what is stored in the registers(what we learnt in csa and aca)......they have a black box view. its the study of algorithms, data structures, complexity theory, all the way down to learning what makes an operating system work. Its the science of computing, not the electrical engineering of the hardware

level 3-IT is next level higher which is the highest level.Information technology is learning to use computers in business or in any practical application.IT studies the impact of applications developed on business/industry. They see to it that these solutions are applied correctly and continue to work in the future.

welll...friends ....i want a few more suggestions or better answers to these basic questions ....which my grand parents want to know .....and now even the interviewer wants to know......

the other day i told my grandpa that i got placed. He asked " how much will you earn?" i said about 25000 a month....so he says " bhagwan jane what you people will do in the office ....i can never understand that ....but as long as they are going to pay you .....i'm happpy!!!!!!! "
