Today, Today, Today....

I went on the computers today to work on the All The Right Type, and I found that I don't have my previous records in it. Mr. Case told us that they had to change the whole thing again because of all the problems we have been having. That means I have to start all over again.

Anyway, Mr. Case did a presentation about the monitor of the computer. There are two types of screens: LCD, and CRT.

LCD- Liquid Crystal Display
CRT- Cathode Ray Tube

Then they measure screens, they don't measure horizontally or vertically. They measure diagonally. So if it's a 32 inch screen, the screen measures 32 inches diagonally.

LCD screen has liquid crystal trapped between two glasses. This liquid crystal is very sensitive so that it can show the images it's supposed to. However, if the glasses are pressed, the image becomes wiggly for a little while in that area. LCD's show more vibrant colours, but are more expensive. They can't refresh too quickly as well so they're not good for games.

CRT screens are a lot cheaper to buy, they are more abundant and they refresh faster. They are good for computer games. People also measure the distance diagonally in CRT including the border part that keeps the screen in. So the amount of space viewed is less than LCD, which is measured without the border.

Well, that's all I remember. Before I could write things down, we were asked to go up the front to watch the rest of the presentations. If I remember anything else, I'd definitely jot them down somewhere.
