I am rather new to computers but I love learning about them. My wife was using the computer and we had a young friend that would help us when we had a problem. He got to the point that he wouldn't answer his phone,so I had to get started. I love tinkering with them now and have kind of specialized in security. I'm glad that he quit answering his phone now. I now have 3 computers. Two are Dell's and one is a home made system that my daughter had. All have Windows XP . Two are Pro. and one is home edition. I keep 2 on line all the time. I have Linksys 54G router with one computer wireless.
