about mouse

A computer would be useless if you had no way to communicate with it. That's why you need an input device. Essentially, an input device lets you talk to your computer. Two examples of input devices are the keyboard and the mouse. We'll discuss keyboards later; for now let's concentrate on the mouse. That funny-looking object that, frankly, looks like a mouse (with its oval body and long tail-like cord connecting it to toe computer) is the mouse. Originally, computers only come with a keyboard. But in 1968 Doug Engelhard invented the mouse. In 1984, Apple Computers introduced the mouse with its Macintosh computers. Shortly thereafter, the mouse was standard equipment on all computers. The mouse acts as a handhold pointing device that allows you to control the actions of that blinking item on your screen known as a cursor.
