Laptop : Windows

A laptop computer is a portable personal computer powered by a battery. We can find the different windows laptops brand in market with same Hardware components. Laptops have an attached keyboard and a touchpad, trackball, or isometric joystick used for navigation. A laptop also has a thin display screen that is attached and can be folded flat for transport. Laptop Components includes the processor, Hard drive, System Memory, Screen, optical drive, External ports, Networking & Video card.
