We are using the computer daily. And the
computer is a laptop computer in many cases.
Then, I think that I will introduce notebook
computers.
A notebook computer includes a display, a
keyboard, a pointing device such as a touchpad, a battery which is charged by
AC adapter, and a speaker into a single unit. It is the general term of a
lightweight personal computer designed considering a user who is premised on
making it move to arbitrary places.
The history is short. The beginning is in
1980s. The first laptop computer appeared in the early 1980s. But it was very
heavy and was able to be carried somehow. The middle of 1980s, the personal
computer which enabled to carry was developed maintaining compatibility with desktop
type a personal computer and it was called “Laptops.” However, many of laptops
were very heavy, and some of laptops were more heavy 10kg. Toshiba announced “Dynabook”
which has been A4 note size and as lightweight as 2.7kg, and equipping the
minimum interface on June 27, 1989. And it had the large sized liquid crystal
display. Toshiba put it on the market in July of the same year. The price of
198,000 yen gave a shock.” PC-9801n” was put on the market by NEC in October,
1989, and these developed the new market of a notebook computer.

Nowadays, while the desktop computers
became superfluous performance feeling for many users, the price of notebook computers
fell and the needs of internal extension also decreased. By such the
circumstances, a notebook PC is received also in a general user as main
personal computers. Since manufacture of a notebook PC was asked for synthetic
technology, such as small size and low-power-consumption of electronic
components, and an advanced design of mechanical structure, it had been
specialty of Japan for a long time. However, the manufacturer who transfers
production of a large-sized model to Taiwan, China, etc., from around 1998, and
the manufacturer who entrusts a design and production to an indigenous firm,
and withdraws from original design and manufacture succeeded one another. The
maker which produces in the mainstream in Japan now is a direct marketer.
In
recent years, a miniaturization and a weight saving progress by development of
the high performance of electronic components, density growth, improvement in
part mounting technology, the performance gain of a material, etc., and the
operation performance is also improving by leaps and bounds. Moreover, the
performance gain of a battery also contributes to development of a notebook computer
greatly. The price of the whole notebook PC falls and a note form personal
computer occupies 50% or more of the personal computers sold all over the
world.
