Also called a Notebook Computer, a laptop is a small battery-powered computer that can be used while on the move. Generally smaller than a briefcase, the laptop can be easily carried around and conveniently used while travelling. A laptop is much costlier than a normal personal computer because of the constraints involved in the design and manufacture of the laptops.

A laptop uses a display less than 3 inches in width and is generally an Active Matrix screen. Most laptops weigh less than 5 pounds and external peripherals can be attached to the laptop with the use of a Docking Station, a small hardware device that allows the computer to be connected to a range of devices like printer or a scanner. Most systems nowadays come with a touch pad that acts as an alternative to a mouse, a keyboard, CD ROM drive and a floppy bay. Information can be transferred between the laptop and the personal computer with the use of software like Briefcase facility in the Windows operating system.

IBM, DELL, Hewlett Packard and Compaq are some of famous players in the laptop industry.
