Laptop

A laptop computer, or simply laptop (also notebook computer or notebook), is a small mobile computer, which frequently weighs 2.2-18 pounds (1-6 kilograms), depending on size, materials, and other factors.

Laptops usually run on a single main battery or from an outside AC/DC adapter which can indict the battery while also supplying power to the computer itself. Many computers also have a 3volt cell to run the clock and other processes in the occasion of a power failure.

As personal computers, laptops are competent of the similar tasks as a desktop computer, although they are classically less powerful for the same price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and resourceful power consumption. Laptops usually have liquid crystal displays and most of them use dissimilar memory modules for their random access memory (RAM), for instance, SO-DIMM in lieu of the larger DIMMs. In addition to a built-in keyboard, they may make use of a touchpad (also known as a track pad) or a pointing stick for input, though an external keyboard or mouse can typically be attached.
