Laptop

A laptop computer is a portable personal computer that typically weighs 4-8 pounds (2-4 kg), although some models can weigh as much as 10 pounds (4.5 kg). The laptop's case usually houses an integrated keyboard and pointing device (such as a touchpad or trackpad), as well as audio speakers. A laptop typically has a clamshell form factor, with a screen on one of its inner sides and a keyboard on the opposite side. Its main component is a display screen, which is usually between 12 and 17 inches (30 and 43 cm) on the diagonal. Laptops are powered by a rechargeable battery or an external power supply.

Laptops are generally used in a variety of settings, including at work, in education, for playing games, and for personal multimedia and entertainment. Laptops are also becoming increasingly popular as a main computing device for general consumers.
