Dashboard?

I want to know what the Dashboard icon does. When I was in Mrs. Ramirez's blog I clicked on it everything looked just like Mrs. Ramirez's blog but in plain type without the background. What is it used for?

First Computer Class

I'm glad that I came to this class. Although I already know some things it is great to hear it explained slowly. There are always some things that I learned by hit or miss and now I am getting the correct explanation. Also, I it is good to get the correct definitions of things associated with the computer.
