When the world s first computer first came out, there was no internet

No, computers at that time were only used for calculations.

And the first computer has not been controversial.

I think that the first computer was only used as a computer to decipher codes, and the Internet absolutely did not exist.

However. Encyclopedia Explained:

The world's first computer, "ENIAC", was born at the University of Pennsylvania in 1946. The inventor is the American Professor John Atanasoff. The US Department of Defense uses it for ballistic calculations.

It is a behemoth with 18,000 tubes, covering an area of 170 square meters, weighing 30 tons, consuming about 150 kilowatts of electricity and performing 5,000 operations per second.

On February 15, 1946, the world's first general-purpose digital electronic computer ENIAC was successfully developed, and the "Moore Group" that undertook the development task was composed of four scientists and engineers Eckert, Mokeley, Goldstein, and Box, and the chief engineer Eckert was only 24 years old at the time.

ENIAC: 1 meter long, 1 meter wide, covers an area of 170 square meters, 30 operating stations, about the size of 10 ordinary rooms, weighs 30 tons, consumes 150 kilowatts of electricity, and costs 480,000 US dollars. It uses 18,000 tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, more than 6,000 switches, and performs 5,000 additions or 400 multiplications per second, which is 1,000 times that of a relay computer and 200,000 times that of manual calculations.

In January 1971, Intel's Hough successfully developed the world's first 4-bit microprocessor chip, Intel 4004, marking the advent of the first generation of microprocessors and the beginning of the era of microprocessors and microcomputers.

In November 1971, Intel introduced the MCS-4 microcomputer system (including 4001 ROM chip, 4002 RAM chip, 4003 shift register chip and 4004 microprocessor), of which 4004 (above) contained 2300 transistors in a 3mm 4mm size, and the computing performance far exceeded that of the ENIAC of that year, and was originally sold for $200.

Apple's earliest logo used before 1976.

The early Apple computer, Apple IIC, was founded in 1976 by Steve Jobs and Steve Wozniak (Wozniak for short). Developed and sold the Apple i computer in that year.

In 1984, the revolutionary Macintosh computer was introduced.

In 2005, Steve Jobs announced that Intel processors would be used for the next year.

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 world's first electronic computer was actually an ABC (Atanasoff-berry computer) and the ENIAC was the second. Previous sources claim that the first electronic computer was called ENIAC (Chinese name: Eniac ) (electronic numerical integrator and computer), which was announced in the United States on February 15, 1946.

The "Moore Group" was tasked with the development of four scientists and engineers Eckert, Mokeley, Goldstein, and Box, and the chief engineer, Eckert, was only 24 years old at the time.

The world's first modern electronic computer, Eniac, was born at the University of Pennsylvania in the United States on February 14, 1946, and was officially announced to the public the next day. At the inauguration of the J.N. Electrical College of Penn, the 170-square-meter, 30-ton behemoth performed its "trick" for the guests - 5,000 additions in one second, which was more than 1,000 times faster than the fastest relay computer at the time. This perfect appearance made the guests applaud.

Measuring one meter long and one meter wide, the ENIAC covers an area of about 170 square meters, has 30 operating stations, about the size of 10 ordinary rooms, weighs 30 tons, consumes 150 kilowatts of electricity, and costs 480,000 US dollars. It contains 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors, 1,500 relays, more than 6,000 switches, and performs 5,000 additions or 400 multiplications per second, which is 1,000 times that of a relay computer and 200,000 times that of manual calculations.
