Can you remember the first time you learned to ride a bike or drive a car? Learning these skills changed your life forever and opened up new horizons (眼界；范围). Learning about computers can be like learning how to ride a bike or drive a car. Once you have invested the time to master the skills, you will never go back to the old days. The new technology is simply too convenient and too powerful.

Technological developments through the years have enabled us to do more with less effort. We have continuously looked for better ways of doing things. Each invention and new development has allowed us to extend our capabilities. Today we see one of the most dramatic technologies ever developed the computer. It extends the capabilities of our minds.

Computers have saved organizations millions of dollars. Furthermore, these same computer systems have opened up new opportunities that would have gone undiscovered or neglected. The computer may multiply what we can do, and the return on investment is high. The growth of computer usage is surprising. On the other hand, the computer can do serious damage. Invasion of privacy (侵犯隐私), fraud (欺诈), and computer-related mistakes are just a few shocking examples.

The computer is like a double-edged sword. It has the ability to cut us free from some activities, but it can also cut deep into profits, personal privacy, and our society in general. How it is used is not a function of technology. It is strictly a function of how people decide to use or misuse this new technology. The choice is yours, and only through a knowledge of computer systems will you be able to avoid the dangers while enjoying the many, many benefits of the computer age.

Have you ever heard of blogs (博客)? If you haven’t, you should have. It’s here, it’s growing and it’s having an influence on our life. Surf the Internet and you’ll find blogs everywhere. A blog, shortened from “weblog”, is a public Internet journal written by one person or a group of people. It is a website in which a person or a group can place news, personal thoughts, text, photos, video or audio files, or links upon which visitors can comment. A blog lets you post on the Internet without having to know web design or be technical. You are given an environment to make dated entries on the topic of your choice which are “published”, so other people can read them.

     Authoring a blog, maintaining a blog or adding an article to an existing blog is called “blogging”. Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer. Objects, such as “text and photos” in a blog can be called “blog posts”, “posts”, or “entries”. The person who posts these entries is called a “blogger”.

Now, somewhere around the world, a blog is created almost every 6 seconds. Because it’s great potential, Bill Gates views it as important as e-mail, BBS, and MSN. He’s trying to make blogs the important tools for future business communications.
