In computing, a keyboard is a typewriter-style keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input device for computers.

When typing, always first place our hands at the Home keys and always sit straight and maintain good posture. Also do not place our hands like we are eating always leave it a rest and put it down. And also let us not take most of our time in the computer of course we should sometimes go out and experience to play and to feel some energy coming from the nature. Remember Computer maybe helpful to us but sometimes it is the cause of our illnesses and poor posture and eyesight.
