There are 4 genrations. We are currently using 3rd generation. The future computers are known as 4th generation of 4G computers.

I find it embarrassing to disagree with VINCENT since he is LEVEL 5 with more than 5000 POINTS.
Howwever, perhaps he will set me straight if I suggest, that, instead of the 5 generations of computers he says, I put down 9 that I have known, such as:
8080
286
386
486
Win '95
Win '98
Win ME
Win XP
Vista
