What I Want to Learn About Computers

Computer is mystery. Once I push a bottom, my message goes to other's computer. Once I push a bottom, a countless amount of information appears on the screen. Furthermore, a harmful virus or something comes to my computer and do something wrong. In my computer, these things happen without my attention. Without my special knowledge about these things, I can easily do these things.
What helps computers to be well secured?This is my first question. Because the Internet or other browsers are so common today, it is natural that every computer around the world is harmed by viruses. Actually, my computer had influenced by such viruses before. Therefore, I want to learn how to secure my computer and keep checking the safety.
How to make a Power Point with high quality is also a thing I want to learn about. When I had prepared a presentation, I noticed that I had a little time to make Power Point. However, I spent a lot of time to complete every slides with some techniques, witch was a kind of wasting time. If I had known how to use Power Point well, I could have made it up faster and had a better script as well!!
I am sorry to tell you my past regret:<..but if I can learn about these things more, I will be able to have more enjoyable time with my computer!

My history with Compuer

No computer would make our lives impossible. We buy things, communicate with others, search anything we want, or even apply to new jobs or universities. Because computer will improve our quality of life, we all need to get used to them. Of course, I have get used to use computers in some extent although I had a hard time to get along with them.
Many many years ago...I guess I was ten or younger at that time, I saw a key board, which was black and had a lot of small buttoms, that was attatched with a computer. I thought it was like a monster because it could control the computer; in other words, I could destroy the computer system if I pushed a wrong buttom. I was scared. I hated to try to push the new buttoms I had never tried to. I had hoped that I could do without it.
When I was about fourteen or so, my mind toward computer began to change. I found it interesting, for I noticed that I could search everything on the Internet!! That was amazing fact for me! "I can search my favorite artiste's official site and know about them!" I was about to jump up from excitement!!
Since about three years ago, I began to use the computer for the class such as Word, Power Point, and Excel. And now, I am using it for assingment of computer class at NIC. As everyone can see, my progress of using computers is amazing! However, the way to master computer is far away from here. Even now, my skill to use it is improving, and on and on.....
