A laptop (also known as a notebook) is a personal computer designed for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device and speakers into a single unit. A laptop is powered by a rechargeable battery. A laptop battery typically stores enough energy to run the laptop for three to five hours, depending on the computer usage, configuration and power management settings.
As portable computers became smaller, lighter, and cheaper and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes.
HISTORY OF LAPTOPS
As the personal computer became feasible in the early 1970s, the idea of a portable personal computer followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968, and described in his 1972 paper as the "Dynabook".
The first laptops using the flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The Gavilan SC, released in 1983, was the first computer described as a "laptop" by its manufacturer From 1983 onward, several new input techniques were developed and included in laptops, including the touchpad , the pointing stick and handwriting recognition.
