LAPTOP COMPUTER
A portable computer small enough
to be held comfortably on a user's lap.
More Detailed Definition:
A small, portable computer --
small enough that it can sit on your lap. Nowadays, laptop
computers are more frequently called notebook computers.
An extremely lightweight personal computer. Notebook computers
typically weigh less than 6 pounds and are small enough to fit
easily in a briefcase. Aside from size, the principal difference
between a notebook computer and a personal computer is the display
screen. Notebook computers use a variety of techniques, known as
flat-panel technologies, to produce a lightweight and non-bulky
display screen.
The quality of notebook display screens varies considerably. Many
notebook display screens are limited to VGA resolution.
Active-matrix screens produce very sharp images, but they do not
refresh as rapidly as full-size monitors.
In terms of computing power, modern notebook computers are nearly
equivalent to personal computers. They have the same CPUs, memory
capacity, and disk drives. However, all this power in a small
package is expensive. Notebook computers cost about twice as much
as equivalent regular-sized computers.
Notebook computers come with battery packs that enable you to run
them without plugging them in. However, the batteries need to be
recharged every few hours.
