4) Answer: a)
A computer mouse is a pointing device (hand control) that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface
5) Answer: a)
Keyboard is used for inputting text and numbers and sends commands to the computer
6) Answer: d)
