<<      If I could invent something new, I would develop a new operation system of a personal computer. Now most of the personal computer users use Windows as their operation system. I have a website and analyze its visitors. According to the analysis, 95% of the visitors use Windows and only 5% use Macintosh as their operation system. I think both of them are good operation system. But they can be improved a little more. For PC users, I think most important thing is its early response. If your operation system is heavy and freezes so often, you may be irritated so much. When we buy a new personal computer, we have many softwares from the begining. We don't use most of the softwares. For example, my personal computer had more than 20 softwares as a default, while I use only Word, Excel, Internet Exploler, and other few softwares. So I want to develop a new operation system that doesn't have many softwares but can move quickly without freezing.      I use Windows Me as my operation system. I bought my personal computer just one year ago. So my computer is not old, but freezes so often. As a default my computer had more than 20 service softwares. Most of them don't take any role for me. So I deleted more than 10 of them to make room for my computer. I don't Microsoft to develop a new operation system that can move quickly without freezing. I don't want any useless function. Instead, I want an operation system that is light and strong to an invasion to some computer viruses.      I have said that I want to improve the operation system. And most of the personal users feel the same way. So one university student developed a new operation system. As you know, the OS is called Linux. Linux is an operation system that has been improved by many users. This means that many PC users around the world have discussed what is the most desirable operation system and improved the system again and again. So Linux can be said to be the crystal of thousands of competent PC users. Even the microsoft corporation uses Linux as their computers operation system. This is because Linux can be resist to many computer viruses.      I don't have sufficient computer knowledge, so I know I can't develop a new operation system. But if I can, I want to invent a new OS. This is because I want my personal computer to work quickly without freezing so many times. I suppose many PC users feel the same way. Once our PC freezes, it takes a few minute to restart our computer. That irritate us so much. So I hope a new competent operation system appears in the near future.
