Amazing Technology

I think that the personal computer in the most amazing invention that has been made in my lifetime. When I was young, I never imagined a personal computer. I remember when my father got his first electronic calculator. Prior to that, he had used a slide rule for calculations in his engineering job. However, with the calculator, he could quickly find square roots of any number. While the calculator was incredible, the personal computer is even more useful and marvelous. Typing anything is very easy. If I make a mistake, I can easily fix it, unlike with a typewriter where fixing errors was messy and sloppy. Printing is also easy. I can make as many copies of any document that I want. Besides just typing, I can use my personal computer to make eye-catching Power Point slide shows, send email, and surf the web. A computer is not only for work-related functions, but also for fun activities. In my opinion, the personal computer has revolutionalized life.
