General Features of Laptops

Laptops are miniature computers designed primarily for mobile use. They are also structured to consume less power. Equipped with liquid crystal displays, most of them use different memory models for their random access memory (RAM). In addition to an inbuilt key board they utilize touch pad (a.k.a track pad) or pointing stick for input, through an external key board or mouse that can be attached. The Laptops were invented when users felt a need to have full featured computers that could be used anywhere. Their predecessors were called "Luggable", heavy storage instruments.

The transition to LCD and plasma displays allowed "luggable" to shrink in size. They also had internal batteries added to them. The laptops run on a single main battery. This battery can be connected to the main power source through an AC/DC adaptor. This power can not only charge the battery but also run the laptop. The battery supplies power to the laptop when there is power failure. Many components of the laptop are similar to the desk tops in structure and functions. The introduction of other conveniences like battery technology paved the way for more sophisticated and sleek portable systems.
