Step-by-step explanation:
1. Touchpad is a device by which we can give some inputs to the computer by touching its surface, but the rest all are those by which we can receive outputs, hence touchpad is an input device.
2. There is only one part of the computer that makes any decisions and that is the Central Processing Unit (CPU). It does 2 things, it does arithmetic problems which are 100% accurate. However, the other thing it does is run applications, such as Microsoft Word, games, power point slides, etc., now applications are written into programming language by human beings, so since human beings are never 100% correct then applications are not 100% correct either. But we generally write 100 % accuracy if questioned.
3. CU is the main unit that controls the flow of data in a computer system.
4. Only hard disk is the secondary storage device which is fixed from the beginning.
5. Except monitors, none of the given devices give us outputs in the soft copy (electronic form).
