What year was the first notebook born?

In 1996, the American "Computer Magazine" mentioned that Compaq launched a laptop computer in November 1982, weighing 28 pounds (about 14 kilograms), which should be regarded as the earliest prototype of a laptop. But IBM refuses to accept this claim, insisting that a laptop called PC Convertible it developed in 1985 is the true "originator" of notebook computers.

The Americans quarreled, and the Japanese on the other side of the ocean were not happy. Because they decided that the world's first true laptop was Toshiba's T1000, which was launched in 1985 with an Intel 8086 CPU, 512KB of RAM, and a 9-inch monochrome display, no hard drive, and could run the MS-DOS operating system.

In fact, the reason for the dispute over "who made the first laptop" is that the Japanese and Americans have different understandings of the predecessor of the laptop. In the early 80s of the last century, after IBM developed a personal PC, people dreamed of developing a PC product that could be carried around. The concept of a "laptop" was first introduced in 1983 by National Electronics magazine, which later evolved into a "laptop" and was introduced by companies including Apple, IBM and Compaq.

In the eyes of Americans, it was the development of the "laptop" that prompted the creation of laptops.

In Japan at the same time, manufacturers such as Toshiba, Panasonic and Sony were keen to develop a product called a "mobile PC", which was based on the IBM PS 2 system and used an external power supply. Strictly speaking, the "mobile PC" developed by the Japanese at that time was closer to today's laptops. In particular, Japanese manufacturers emphasized portability in the development of "mobile PCs", which is in stark contrast to the "laptops" designed by Americans that are so cumbersome that they need to be carried to move.

More importantly, it was after the launch of Toshiba T1000 that various new technologies and new products related to laptops appeared, and the market began to develop rapidly and comprehensively.

In 2001, the Journal of the Association for Computing Machinery (ACM) wrote in a report commemorating the 20th anniversary of the birth of the PC: "In 1985, Toshiba introduced the T1000, which brought the concept of 'laptop' to people for the first time. ”

T1000 produced by Toshiba Corporation of Japan in 1985

The laptop was first produced in 1985 with the model number T1100, which was designed by Toshiba of Japan, with an Intel 8086 processor of less than 1MHz, a 9-inch monochrome display, and an MS-DOS operating system.

The size of the T1100 is 12 2 11 inches, and the weight of the whole machine is pounds (total kilograms). With a clamshell design, it offers a full-size 82-key keyboard, an inch of 720kb hard drive, 512kb of RAM, and a built-in modem.

Summary. In English, laptops have two corresponding words, one is laptop, the other is notebook, if it is only understood according to the meaning of "portable" contained in laptops, then the world's first laptop should be produced by Compaq, which launched a portable computer in November 1982, weighing 28 pounds (about kilograms), although a little heavier, but still able to be carried or carried.

If according to the original intention of laptop, the laptop speaks, the world's first laptop was actually invented by Toshiba, Toshiba launched its own laptop T1000 T1100 in 1985, the T1000 weighs pounds (total kilograms), most people agree that this is the world's first laptop.

In which year was China's first computer born, then in which year was China's first laptop born, in English, laptop has two corresponding words, one is laptop, one is notebook, if it is only understood according to the meaning of "portable" contained in laptop, then the world's first laptop should be produced by Compaq, Compaq launched a portable computer in November 1982, weighing 28 pounds (about kilograms), although slightly heavier, But you can still carry it on your shoulders or carry it. If according to the original intention of laptop, the laptop speaks, the world's first laptop was actually invented by Toshiba, Toshiba launched its own laptop T1000 T1100 in 1985, the T1000 weighs pounds (total kilograms), most people agree that this is the world's first laptop.

China's first computer was born in 1958. In 1958, the Institute of Computing Technology of the Chinese Academy of Sciences successfully developed China's first small tube general-purpose computer 103 (Bayi type), marking the birth of China's first electronic computer. The 103 machine is kept in Qufu Normal University, Shandong.

The 103 machine is huge, and there are several large cabinets in the main unit alone, covering an area of 40 square meters. It is very sophisticated, with nearly 4,000 semiconductor germanium diodes and 800 electron tubes in its body.

The first inventors in the world were the Americans John Wmauchly and Eckert J. Prespereckert.

Computers"eniac"It was born in 1946 at the University of Pennsylvania in the United States.

ENIAC, the world's first electronic computer, used 18,000 tubes, covered an area of 170 square meters, weighed 30 tons, consumed about 150 kilowatts of power, and could perform 5,000 operations per second. Used by the US Department of Defense for ballistic calculations.

ENIAC uses electron tubes as components, so it is also known as tube computers, which is the first generation of computers. Tube computers are prone to heat up due to the large volume of tubes used, large power consumption, and heat.

The first computer was designed by the British mathematician Charles Babbage in the 19th century and was called the "Babbage Giant Computer Annihilation", but due to technical constraints and financial problems, the computer was never fully built. The first real computer was a spinal sail called ENIAC designed and built by John Bickner and John Presper of the University of Pennsylvania in the United States in the 40s of the 20th century.
