In what year did the computer come out, and in that year did the computer appear

In 1946, the University of Pennsylvania successfully developed the world's first program-controlled electronic computer ENIAC. 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. ”

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.

A computer is a machine that uses electronic principles to process data according to a series of instructions. A computer can be divided into two parts: a software system and a hardware system.

The first computer was the ENIAC general-purpose electronic computer born at the University of Pennsylvania in the United States on February 15, 1946.

Humans refer to computers that do not have any software installed in Oak Air as bare metal. With the development of science and technology, some new types of computers have emerged: biological computers, light beam computers, quantum computers, etc.

On May 24, 1954, the transistor electronic computer was born.

1、Intel UHD 617 is a core graphics card in Kaby Lake GT2 (Apple's special supply),Fu Yinru is mainly integrated in the 7th generation mobile processor,The performance should be similar to UHD 615。

2. After flipping through the seventh-generation mobile processor, the seventh-generation i5 processor with the main frequency seems to be only i5-7Y54 and i5-7Y57 in line with the models in the figure, these two processors were sold in the third quarter of 2016 and the first quarter of 2017, and it has been at least 5 years now.

3. The specific** is not very clear (Apple's things can't be valued with the hardware**), but these two processors are now carrying the second-hand ** of about 200 yuan. And the performance of these two processors is also very low, which is basically the level of the i3-7100U of that year.

Comparison of running scores.

For many computer users, Apple is leading the computer industry, driving technological innovation and changing the way people think about personal computing. Over time, Apple has continued to strengthen itself and innovate, bringing surprises to users every time and attracting a large number of Apple fans. Here are the top 11 Apple computer designs rated by pcworld:

3.Lisa: Launched in 1981 and named after the daughter of Apple CEO Steve Jobs, Lisa was the world's first personal computer to combine a graphical user interface (GUI) and a mouse.

But because of the high price of $10,000, it is considered one of Apple's worst products.

5.Mac II: Launched in March 1987, it was the first open scalable computer, and the expansion options included two 800K floppy drives, hard disks, and an 8-bit 256-color 640x480 color display, which was quite impressive at the time.

6.Macintosh Color Classic: Released in 1993, it has been a collector's favourite as it symbolizes the union of two eras, with a color display for the first time.

7.Mac Portable: Launched in 1989, it's lightweight, portable, with a 10-hour battery life and $6,500.

8.Mac 20th Anniversary Edition: Launched in 1997, it sold for a whopping $7,499, $5,500 more than the Mac 5500, which was comparable at the time. A year later, Apple lowered its selling price to $1995.

9.iMac: Launched in 1998, it attracted users with its unique design and outstanding ease of use, and turned Apple into a profit a year later.
