Drawing Tablets: A device used to draw images which can then be transferred and stored onto a computer. Tablets are more effective for drawing than using software on laptops or computers. This is because instead of using a mouse to draw there is a pen provided making drawing faster and more accurate. The tablet can also be connected to the computer were files can then be transferred. However, there are a number of disadvantages of using drawing tablets. More time would be spent drawing on the tablet than would be the case if paper was being used. Tablets which are of any use to an IT professional would be quite expensive as they are bigger than the average tablet.
