Computer mouse is very essential thing when you
using computers, now days in laptops, there are touch pads but when
using mouse it is very easy.
In 1963, the first mouse invented by Douglas
Engelbart at the Stanford Research institute. This inventor
Douglas Engelbart also invented the hypertext (Secret codes). In this first mouse used two wheels positioned at a 90
degree to each other to keep track of the movement. That's how it
works.
