Summary:

This article talks about two questions; the first one is what the difference is between the C.C.F.L. laptop screen and the LED laptop screen. C.C.F.L. which is named cold cathode fluorescent lamp, is older and is a cheaper method, but it has some drawbacks, like it includes mercury and it is bad for the environment. The next one is the LED screen. It uses less power and is friendly to the environment, but it is more expensive. Some people prefer vibrant colors or may choose glossy displays. Matte display has less color depth and contrast. The second question is how to protect confidential information. The author suggests making a password archive. Different operating systems have different tools to keep security. Or we can make some copies, install a firewall or unplug the drive. At last the author introduces a tip for icons in Windows 7.

Reaction:

This article is a personal tech who invites questions and answers; he taught many useful experiences to the reader. From his article, he talks about the C.C.F.L. and LED, and how to keep the confidential information in the computer, I just want to share my experience with others.

When I was in high school, my parents had already bought a secondhand laptop for me. During that time, the laptop was much more expensive than it is today, but the quality and function were less. My computer is a C.C.F.L. laptop screen. One day I just put my laptop on the desk and typed. Suddenly the screen went dark and nothing appeared any more. I had tried to find the issues but it did not work. So at last I had given up and prepared to send it to the factory to repair. Afterward I packed the laptop. I found something like water, but it had a the silver color, on the desk. My parents were very nervous and we thought it could be mercury. And we cleaned it very carefully. After that we never chose the cheaper laptop again. And I prefer to pay more money to buy a safe computer. Actually nowdays the C.C.F.L. has almost disappeared. The famous brands of computer manufacturers choose the LED much more even though it is a little expensive.

I have never put my important information or documents on the desktop, but if the computer gets a virus, no matter where I put them, I will still lose them. So I would like to put my important documents in another device like a flash device. Even though the computer has been hacked, but I still keep them. And I don’t agree with the author’s statement that we should set a password archive. it is too easy to decipher the program, and it is inconvenient to open them. So installing security software should be a good idea.

I like the facts that they can share skills. I can learn a lot of information from these answers. So I really hope there will be more articles like this.
