Red is a primary color, you can't mix 2 to get red. Blue is primary, too, and so is yellow. You can mix any of the above colors to make another color. ie: red and yellow make orange. red and blue make purple. blue and yellow make green. yellow and green make light green. white and red make pink.
There are quite some differences between an optical mouse and a laser mouse. One of the most noticeable differences is the type of rays coming out of the mouse. Now,we all kâ¦now that from an optical mouse there is (usually) a red light coming out and on the other hand, the laser mouse does not produce such light.
Let's take a look at two examples: Example: Telling the difference between input and output devices. An LG LCD monitor. When you are using the monitor it displays things that you are doing, such as moving windows and clicking on website links. At no point do you click on the screen or put anything into the monitor. The only thing it does is output information, therefore it is an output device. Easy! An optical mouse. A mouse is used to move a little cursor around the screen, clicking and dragging as you go. if you let go of the mouse, the cursor will stop. The computer is relying on you to move the mouse, the mouse won't move on its own! Therefore it is an input device. Exercise: Input and output devices.
