The advantages of an IT solution is that all the data that you have worked on, is stored in a secure area in the computer, however, the manual solution can get easily lost or ripped. The IT solution's presentation is better than of a Manual solution. An IT solution can easily remove any faults typed on the computer. However the Manual Solution has to be either rubbed off if using a pencil making it look messy or sometimes crossed off if using a pen. The IT solution can help people to type essays, coursework, stories etc much quicker than of a manual solution.
