Siheyuan starts from a better life

Chapter 792, booting up

"Now, let's test the operating effect of this computer." Jiang Yan said, and began to enter some calculation commands in front of the computer.

As Jiang Yan pressed the OK key, a complex sequence of numbers and symbols scrolled rapidly on the computer screen, and the computer started to work. Extremely complex scientific calculations can be completed quickly and easily on a computer.

Then the result of the operation is printed.

"Let me take a look, let me take a look." Professor Zheng quickly took the paper on which the calculation results were printed and began to read it.

"This, this." Professor Zheng looked at the printed results and was speechless.

"What's wrong, Old Zheng? Is there a miscalculation?" Seeing that his old friend remained silent, Professor Li asked quickly.

"No, no, correct, correct, completely correct, it's just that the calculation speed is too fast."

"On these data, all our staff have been calculating day and night for a full week. This is only ten minutes, only ten minutes."

When Professor Zheng said this, he began to sob.

As a person from the Academy of Mathematics, no one knows the bitterness of this. Although the country has been established for nearly ten years, Jiang Yan has produced a lot of good things for export to earn foreign exchange, but compared to the big country These are still a drop in the bucket, and they still need to introduce some things from foreign countries.

Unlike Mao Xiong and Ying Jiang, who have the deep pockets to conduct multiple experiments in exchange for data, our scientists can only make repeated calculations on manuscript paper to ensure that the theory is foolproof, so that they can start to create corresponding test products. You know, these things, calculations How difficult is it.

According to what Professor Yu later said, the paper they used to calculate could cover the entire next door. Although it looked very exciting, there was still an indescribable bitterness. With the addition of computers, many scientists can get away from complicated calculations. Professor Zheng couldn't help but be excited by investing more energy in studying more things.

"Ah?! This... this... this, then calculated in this way, its calculation speed is more than ten times faster than our existing computers!" Professor Li caught the words in Professor Zheng's words, and after some calculation, His eyes widened immediately.

"The memory capacity has also been increased several times, allowing more data to be stored!" Jiang Yan said calmly from the side.

After finishing speaking, Jiang Yan clicked on the right side of the computer, and a floppy disk appeared in Jiang Yan's hand.

Floppy disks were the earliest removable media used in computers. Reading and writing floppy disks is done through floppy disk drives. Floppy disk drives are designed to accept removable floppy disks, and currently the most commonly used ones are 1.44-inch floppy disks with a capacity of 3.5MB. Floppy disks have slow access speeds and small capacity, but they are removable and easy to carry. As a removable storage method, it is ideal for small files that need to be physically moved.

"This is a floppy disk that can be read on a computer. It has a capacity of 1.44MB and can store almost Chinese characters. It can be moved."

"It's so exquisite. This thing can actually store so many words. It's also easy to carry." Professor Zheng took the floppy disk and looked at it repeatedly.

Jiang Yan is not too cold about this thing, but the current technology can only produce this floppy disk. However, seeing the two professors admiring it so much, Jiang Yan curled his lips disapprovingly. In his own time, this thing has long been After being eliminated for decades, an ordinary mobile hard drive in later generations has 5G of storage, which is where it comes from.

"According to today's computing speed, I can say without reservation that the performance of our computer is probably close to the world's advanced level!" Professor Liu put the floppy disk in Jiang Yan's hand and said. Everyone was quite shocked when they heard the words of the authoritative Professor Liu, but Jiang Yan still smiled and looked at Professor Liu and nodded solemnly.

However, he thought, if they knew that this computer also had a supporting operating system and programming language, the computing efficiency would be even more amazing, and he didn't know how they would react. Unfortunately, the system code cannot be displayed for the time being.

The candidates present are not reliable enough. If such high-end technology is exposed, there will inevitably be a risk of leaks. Jiang Yan decided to gradually show it to everyone when the system is developed and reliable candidates are in place. I believe the shock will be even greater then.

Now, let everyone slowly adapt to and accept the concept of third-generation computers.

However, Jiang Yan will continue to develop this programming. He wants to develop a set of Chinese programming. Although he is not a professional computer programmer, when controlling CNC machine tools, he must also be able to do some simple programming. Otherwise it cannot be controlled.

Thinking of the popular programming languages ​​​​of later generations, Jiang Yan couldn't help but curse in his heart. Almost all programming in later generations was programmed in English. There are very few Chinese programming languages ​​​​on the market. English is not Chinese fonts and can be combined at will. They can form new characters. Their characters are basically things that were invented first. There is also the term "computer language" internally. In order to learn computer programming, Jiang Yan in later generations had no choice but to learn English. During that period , it’s really dark and dark, I’ll be in tears if I talk about it too much!
Who told others to invent the computer first and the programming language first? There is no way. Calculate the time. This third generation computer was only invented abroad not long ago. If I had to program this computer first, they would all follow their own ideas. Come.

You know, Chinese is the most difficult language in the world to learn. If it were used as a computer programming language, it would probably make those foreigners want to die. Thinking of this, Jiang Yan looked excited.

Let these gringos enjoy the hardships they have endured.

Then it would be better if I get another Chinese keyboard. One plus one is not simply greater than two.

The first personal computer was invented in 1981, and it was only 67 years ago. He still had more than ten years. Jiang Yan decided to use personal computers as one of his future development directions.

Taking back his mind, Jiang Yan looked at the successfully started computer, his heart filled with joy and satisfaction. This is just the beginning, there is still a long way to go, but this also represents the beginning.

After the success of the computer, many big names came to Jiang Yan's research institute to visit, study and even negotiate. According to Jiang Yan's calculations, it would take about half a year to produce such a computer.

After the meeting, it was decided that they would send the computer to the place where it was needed most - the Northwest. The situation there was urgent and the calculation workload was heavy, so a fast and accurate computer was needed.

However, the system on this computer is obviously not suitable for use now, and I have to design one myself, so after the meeting,
Jiang Yan Jiang Yan immediately began to work overtime to design a simplified computing system. This system only retained the necessary computing functions and discarded other unnecessary functions. After working day and night, a week later, a streamlined and efficient computing system was created. The system is finally designed.

On this day, Jiang Yan found the leader of the First Machinery Department.
"Boss, the Northwest is in urgent need of a computer. Please make arrangements to send this computer. Also send this operating instructions." Jiang Yan handed the operation manual he wrote to the top leader.

"Leave it to me, don't worry, I will seize the time and secretly send it to the northwest, and send someone to explain the operation method clearly." The big leader said with a firm expression.

After leaving the big boss's office, Jiang Yan breathed a sigh of relief. I believe that with the help of this computer, the scientific research conditions in the Northwest will be greatly improved.

But then we need to produce new computers for the two units that can go to heaven and earth.
