The notebook Computers

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.
