I answered "Hardware". I consider the OS to be under the catagory of Hardware. Because hardware without the OS is an expensive doorstop.
Soon after I bought my first PC I was interested in "software and programming" but I was attending a university that was Mac Centric. I didn't understand this until I showed up for Pascal Programming and was told, by the professor, that I was "stupid" for owning an IBM compatible. This effectively "put me off" of being interested in programming. Which is a shame as I can see I would be a much more capable person if I was proficient at such.
But I am naturally a "Hardware" person. It's literally a genetic predispostition. I've applied the same talents on everything from chainsaws to jet aircraft. When I first experienced a problem with my first PC, I found material that described how things functioned. By process of elimination I decided what part to change out first and fixed my problem. From there I just kept learning how computers worked.
That was about 17 years ago. Now a person can simply describe the symtoms they are having and I can suggest what the cause could be, and how they can verify this cause. But my talent goes beyond just good troubleshooting.
An example would be a case where a friend of mine was having a problem with an Epson inkjet printer. I cycled the power on the printer one time and determined that the belt that carried the print head might be worn. I then used a finger to push the print head back to what I intuitively guessed was it's "parked" position. After this the printer functioned fine until that belt finally broke. My friend was really suprised by this, and frankly so was I, but I've always had a knack for doing this kind of thing.
It has something to do with how I think. Specifically it seems to stem from how I deal with feedback from my subconcious mind. I only know it's not something I was "taught" to do. And it only works for things, like computers, where I have extensive experience.
The irony is that, lately, I've really gotten sick of computers. Maybe what I'm really tired of is the hype. I bought and installed Windows XP x64 and was really disappointed. Now I know many of you might say that Vista will be better. But I'm not sure anymore.
I have been using Microsoft Operating Systems since my first PC with DOS 3.3. I still have copies of 4 versions of DOS and about 12 versions of Windows. (Yes I'm a software packrat!) Every version of Windows was supposed to be better than the last. Yet none of them has ever fulfilled the potential they "seemed to promise". Now I just can't believe the PR spin anymore.
Just thinking about it makes me depressed......
Oh I know! This is an excellent opportunity for me to go study accounting and law.
