Modelau 3D Cyfrifiaduron Gliniadur.

Mae'n gyfrifiadur personol cludadwy gydag elfennau nodweddiadol cyfrifiadur, gan gynnwys arddangosfa, bysellfwrdd a dyfais bwyntio (fel arfer pad cyffwrdd neu blat cyffwrdd), yn ogystal â batris y gellir eu hailwefru ynddo.

Mae gliniadur yn derm ehangach, mae'n berthnasol i liniaduron, llyfrau net, llyfrau clyfar.

Trosglwyddir y cyfrifiadur cludadwy hwn pan gaiff ei blygu, mae'n eich galluogi i ddiogelu'r sgrin, y bysellfwrdd a'r pad cyffwrdd yn ystod y cludiant. Mae hefyd yn gysylltiedig â hwylustod cludiant (yn aml mae'r gliniadur yn cael ei gludo mewn bag briff, sy'n caniatáu i chi beidio â'i ddal yn eich dwylo, ond ei hongian ar eich ysgwydd).

Mae cyfrifiaduron cludadwy yn gallu cyflawni'r holl dasgau â chyfrifiaduron pen desg, er y bydd perfformiad llyfr nodiadau ar yr un pris yn sylweddol is.

Hefyd, trwy gysylltu gliniadur (gyda system deledu neu gysylltydd HDMI) â system deledu a / neu sain, gallwch ei ddefnyddio fel canolfan adloniant cartref amlgyfrwng (gorsaf amlgyfrwng).

A laptop or laptop is a portable personal computer that houses typical PC components, including a display, keyboard, and pointing device (usually a touchpad), as well as rechargeable batteries.

The laptops are small in size and weight, and the battery life varies from 1 to 15 hours.

Depending on the size, weight, capabilities, and purpose, there are several types of laptops:

Sub-laptop (ultra-portable);
Thin and light (thin and light);
Desktop substitutes (Desktop + Notebook Desknote);
For use in difficult environmental conditions.

The idea of ​​creating a portable computing machine “the size of a notepad that has a flat-monitor and can connect to networks without wires” was put forward by Alan Kay, chief of Xerox’s research laboratory in 1968, calling it Dynabook.

1979 NASA commissioned William Mogridge (Grid Systems) to create the world’s first Grid Compass laptop (340 KB CMD RAM, 8 MHz Intel 8086 processor, fluorescent screen). This laptop was used in Space Shuttle.

The first Osborne 1 general-purpose model (weighing 11 kg, 64 KB RAM, 4 MHz Zilog Z80A processor, two 5.25-inch drives, three ports, including modem connection, 8.75×6 monochrome display, 6 cm, containing 24 lines of 52 characters; 69 keys) was created by the inventor Adam Osborne in 1981 and was released on the market for $ 1795. Due to a marketing mistake, the beginning of sales of Osborne 1 was announced long ago the company went bankrupt before the first cars came into sale.

1982 Compaq successfully introduced the IBM PC-compatible laptop computer based on the Intel 8080 processor. In 1984, Apple released the first LCD laptop; In 1986, IBM introduced the first “transformed” model of Intel-based laptop (5.4 kg mass, 3.5-inch drive) for $ 3,500.

1990 Intel introduced the first dedicated processor for mobile PCs, the Intel386 SL, and also introduced a power-down technology that extended battery life.

A laptop is essentially a complete computer. But for mobility, portability and energy independence, all components have their own peculiarities.

The laptop keyboard is made with special technology and is several layers of thin plastic with pads, which allows to reduce the thickness to several millimeters.

The laptop case is usually made of high-strength plastic. Inside it is covered with a special thin metal foil to isolate the electronic stuffing from the effects of external electromagnetic fields. On the perimeter, as a rule, made of metal-cord, which gives additional strength of the case. It also contains COM, LPT, or VGA connectors, etc. for connecting external devices, and usually a Kensington lock.

As a pointing device in laptops, the so-called touchpad is a widespread touchpad that responds to the touch of a finger.

The laptop matrix is ​​a full-fledged LCD monitor. The top cover of the notebook has everything you need to get it right – the matrix itself, the data loops, the inverter to keep the backlight on and some additional devices (for example webcam, speakers, microphone, antennas for wireless Wi-Fi modules) and Bluetooth).
