Too old

I thought computer were invented during 2000's because my parents always tell me that I am such a lucky student because there are computers that helps me for my homework and they also told me that during their childhood they don't have any computer.

But I was wrong, computers are very very old. It is older than my parents. Computer were developed according to the trend and time. As time passes by they become more efficient and useful. As of now, there are 5 Generations of Computers, I wonder if when will be the time that it would be 6. ..

FYI
