How I Use Technology and Computers

I use a computer at home, work and for school. I have access to Windows Vista and XP. At one time I did have and iphone, I learned a lot of stuff on that. I am always wanting to learn new ways on how I can improve the way I use a computer. I often visit the same sites, such as facebook. I really do not know to much about the hardware but software I am pretty familiar with. I could try to learn how to maintain the hardware and software. I really wish I knew how to upgrade my harddrvie and add more RAM to my computer, I could really use an upgrade. I do allow my sister to use my computer but very seldom. Majority of the time I am using it. My sister is very clueless when it comes to operating a computer.
